4 miles EVERY 4 HOURS for 2 DAYS | David Goggins Challenge with my DOG. 

Nixon with his stubbies running 40 miles proud of both of y’all. Good on ya man

Did my 1st run in 30 years yesteday - and I blame you. Had no intention of running until finding your channel a couple of weeks ago

I resonated with the "empty classroom" story. I was 287 pounds for years. Unfit, unwell, and super unhappy. I just decided to go for a walk an it changed my whole life. I could barely do half a mile. Fast forward a few months I was at maybe 4 miles and the rain was setting in. Everyone else cleared the track or the streets it seemed. It felt really good to be out there, alone, in the rain, dark, and cold. Felt like I wanted it more. Now I'm 167 pounds and regularly run between 10-12 miles per day.

Having interchangeable doggs was crucial for success for this event. Having an interchangeable twin brother could be the key to winning future medals at races🥇

Running with my dog is what makes me happy. Seeing Lincoln enjoy himself this much made me a little emotional 😅

That 4am “empty classroom” wisdom was a gem! Thanks for that and another very enjoyable video

"Getting it done when nobody else can be bothered". That's 100% the mantra to live by. Good on you.

You're my guy now. We're the same age, with wife, kids, running a business and struggling like a mofo to get healthy again. I relate to everything you say here on this channel. I am 25 lbs down and another 25 to go. Now the struggle is to get to a level where I do not obsess about calories, so your video on temptation, association, accountability hit home hard. I am determined to get to a point where this is a habit/lifestyle that I don't have to think about as much, either-wise I am going to fall back to 50lbs overweight again, and or more. My metabolism has slowed so much that losing a pound now takes much more effort than it did 6 months ago. $%& its hard.

I can’t thank you enough. Your videos get me through the tough workouts. I really was only planning on doing two miles on the treadmill but I saw this video was about 30 minutes long and you were doing 4 mile runs so I got through the 4 miles as well. I was searching through past runs a few days ago and I came across a run I had done with my son before he passed away last year. I didn’t know he had created a Strava profile and logged every run we did together. It was incredible to be able to go back and see each one of the runs we did. My son was a competitive rock climber but running was just not a thing he liked to do. He would do it simply because I wanted him to run with me. It was great to relive those runs but it also was difficult to allow myself to remember what is now gone from my life. Please keep making videos. There are lots of us out here who need inspiration and motivation just to get out of bed in the morning. Your videos give us that hope. Thank you, thank you, thank you.

Loved the "empty classroom" part. It very much feels like that a lot of the time doesn't it? The constant effort and commitment to not slip back to old and unhealthy ways.

Well done, I especially appreciate that you listened to your dog. When he was tired you let him home that is awesome. Great video, now I am thinking to do this challenge in the summer.

Mate, genuinely, that school analogy was so profound. I watched this video last night and I’ve not been able to stop thinking about how this perfectly summarises my attitude towards training, but also how much I want to distill that into my kids

Me and my 17yr old son did this last year. Was tough. We added 1 more run on the Sunday to clock 52miles total (we started on the Friday). Seemed like a cool thing to end on a double marathon. Awesome channel.

Great effort. I particularly enjoyed the Lincoln run.. That little fella was fantastic 😁👏👏 kudos to Nixon too.

Empty Classroom!!!! What an incredible metaphor! "Getting it done when nobody else can be bothered" Thanks Mark!

I watched this video last night. Really enjoyed it. When running in the rain today I said to my husband, “we are in our empty classroom”! Felt brilliant! Thanks for that one. I’m going to use it a lot!

Anybody else do 4x4x48? Tough, not tough, bonkers? All of of those? 😂. Also - if you check out the new website please bear in mind it has only just launched so will have lots more added over the coming days-especially all the gear I use and events I take part in. It will get officially launched in about 10 days time as it is only mentioned on this video until then........ So you are basically getting a sneak preview :)

Love this channel so much, I think you’re becoming my favourite - so consistent and always high quality. Awesome👍

Mark, thank you for this channel. I’m 37 and started to run and eat well a few weeks ago because I’m overweight and I have mental health issues sometimes. Seeing you and how your body, mind and cardio fitness has improved over the years is really motivating for me and when I need a bit of motivation I will stick on one of your videos. I see your medals on the wall and think it’d be great to have something to look at as achievements for myself and nobody else. Good luck to you in everything you do.

Dude, another brilliant video. Your Sunday morning 4am run, so true. That is your competion and your classroom. Inspirational stuff. I'm at the start of my own journey of being more active/weight loss/being above average. Your videos and humour help so much. Thank you

That was epic. Well done to you all. I really enjoy your videos, you have a really good way of coming across. Down to earth and very motivating.

Loved seeing you and your dog complete this! We just completed ours as well. We're surprised how little soreness we are also feeling!

Loved the chaos of you guys leaving with all the dogs! Way to go. Your last run was literally twice as fast as my regular 4 mile runs. Very impressed!

Well done mate .. you keep me motivated!! Did my first half marathon on Sunday... after 4 years no running. Did it in 1.43 after 7 weeks of training from the couch .. your videos have helped .. so thanks

Awesome! Great video. I really loved the "empty classroom" spiel. That sums up what goes through my mind in the early hours on long runs.

oh man the empty classroom bit is the most inspirational speech I have heard in a long time. thank you. I am currently running the challenge of doing 20k steps a day. not running, cause my knees don't do well with high impact, but just walking. Also with my dog. If I'd try this out my best bet right now would probably be cycling cause just walking it would probably take too long XD

I ran this also! The hardest time for me was Sunday morning when I woke up a little late for my 2am and 6am runs, for reference I am in the central time zone in the US. I put in the miles, but did end up walking one session. I really think the sleep deprivation was harder than putting in the work. I averaged 9-9:30 miles. Still sore 2 days after finishing.

Well done mate, great effort and the empty classroom speech was on point. Did my first run in 10 years after your 5k run video popped up in my recommendations. That was Monday. Ran again yesterday after a squat session and I plan on going today. Got a park run booked in with my brother on Saturday. Cheers for the kick in the arse

That was very cool! Great work! I didn't know about it, but will schedule that, I'm always up for a challenge! And loved the empty classroom analogy, that was a real motivation boost, really well said. Lots of fun in all your videos, enjoying whenever you post a new one. Thanks and cheers!

"when nobody else can be bothered".. this really hit me. I think I need to prioritize my shit and be out more. Moving. Something. You are an absolute unit of inspiration. Thanks for making the content you do.

Been watching you since the beginning. This is your best video yet. Humble and funny. This is where you shine. Well done Mark, you deserve all the success in the world.

Sir thank you for the practical advice and straightforward approach to your videos. I have watched several now and I have been enjoying them. I also did the 4x4x48 and I really enjoyed it as it is my first venture into ultra territory. In the last 9 months, I have re-learned my love for fitness and running. Happy to find other like-minded souls plodding along a similar path. Keep up the hard work!!

Watch your videos but never comment, really enjoying all your content!! ps. did this challenge last year, such a rewarding experience!

Good video and humour Mark 🙂 What you said about classrooms reminded me of this, “Today I will do what others won't, so tomorrow I can do what others can't.” - Jerry Rice. Great words to live by! Keep up the great vids 👍

The empty classroom minute at minute 15 was was one of the best minutes you have put and what I try to tell my son. Thank you.

Great effort Mark. Can't believe little Nixon smashed through that many runs, BEAST! Also the cat section, hilarious - little dogs pulling like freight trains :D

I have signed up for a 60km adventure race in June . I had Never run before Christmas this year and struggled with 2km at the start! I’m running 45/50k a week now and putting in the work. I loved that empty classroom story and can totally relate. It gave me a little goosebumps and made me realise I’m really looking forward to the race even tho I’m finding the training load hard with life and work etc. thanks💪🏻 love your content

I've got my first half marathon on Sunday (march 13th). I went from not running for around 10 years to running a 10k race back in October last year after doing 3 weeks training, since then I've knocked nearly 13 minutes off my 10k time (1h13 to 1h). I'm sat in my running stuff putting off a 5k and your empty classroom motivation has massively made me get up and jump on the treadmill to get this 5k done. 👌

Loved this! Nixon loving 4am life! I'm taking on this challenge next weekend with my dog as well. Like you say everyone deals with it differently so let's see how the sleep issue goes! All the best.

Another great video Mark. Well done to you and your training partner Nixon. Looks like the training group is growing, Lincoln crushed his run. You have certainly given me the desire to do this challenge next year! Keep up the good work!

Great video Mark! The only downside of doing this in Canadian winter was running into freezing rain half way through my 11th run and trying to figure out if I was going to have to crawl the last mile and half.

Omg! I was sooo waiting for this! Woohoo! Congrats to you, Nixon, and Lincoln. 🎉 It was my first year doing it and I'm in Canada, -8 to - 12 Celsius, and tons of snow! And brother, run 6 to 9 no joke, 2 bruised toes, nails will probably fall off too. But I'm glad I did it. And as usual, you don't disappoint as I'm laughing now. Thank you for being YOU! ❤

Only stumbled across your channel last week. I love your videos! I’ve also stumbled into running (I stopped when I left school in 1994. Started again about 2 months ago aged 45), cycling and swimming, and last week signed up for a sprint triathlon at the end of this month. My family secretly think I’m losing it😂. Done 4 park runs (can only do them out of school term time as I work on Saturday mornings - no empty classroom for me - it’s full classrooms on Zoom!), which started at 32 mins. Got my pb two weeks ago 23:56 This time last year I was 3.5 stones heavier than my twin brother. Today I weighed in the same as him. He hasn’t put on weight. I feel as happy as I have for a very long time and taking great inspiration from your fun, down to earth videos. Thank you (P.S. Zwift looks like too much pain for me - but great fun watching you suffer instead 😂)

seeing you run with your dogs really made me smile, thanks for the video.

Been watching you for a couple of months now since I started my own running journey after turning 30. The empty classroom mindset has stuck with me and on my 6am Sunday morning run yesterday with no one else around it showed true. Thanks for the work mate. Keep it up

Watching this at 6am just before a 100 mile mtb ride and loved your classroom observation, funny how you find clarity in those moments, usually at some stupid time of the morning. You’ve geed me up for my ride. Well done on the challenge👏

Great video! I am a 45 year old runner trying hard to always get better. Your videos are inspiring. Thanks for sharing your journey!

I recently started running (for the first time ever in my life) together with my dog. Then I found your videos yesterday. Now I’m motivated to run even more 💪🏻

This channel is definitely above average. Can’t lie.. mainly watch it for the Nixon content. I don’t run, ride or wear a medium t-shirt, but I row and my lifting is above average. Good stuff.

Mark, another brilliant video. They have inspired me to change my life! 3 stone down since the new year, parkrun time down to 25 from 34. Thank you !!

I did it last year (got the T-shirt etc) , could not do it this year as I am having to work the weekends over March. I found the Sunday 00:00 and 04:00 the toughest stints but, chilling out at 9-9:30 min miles, meant I was back and showered in an hour, have a hule shake (or something more solid depending on the time of day) , rest if I need it (lots of catnapping) and pushed the last 4 miles when it was over! Well done, relatively speaking there are not many of us that have done it. I managed to raise over 600 quid for my charity of choice if I remember .. a rewarding challenge. It's not a spartan Ultra or anything like that but it does tap into something unique .. got a bit of a buzz the last two runs. A bit warmer this year last year it was about 0 most of the weekend. On a side note, it really benefitted my vo2max score on the Garmin very strange as the runs are not long and not very fast but it shot up by 2 over the duration of the event.

Hey Mark have watched a few of your vids now and I just love your enthusiasm gives me such motivation to go out and crush it 💪 (also your dogs are adorable!)

I did the 4x4x48 last weekend. Had no issues with fuelling, blisters or the running. What I found hard was the sleep deprivation. IF you are lucky enough to nod off, when I woke up for the early hour run it was horrendous. Literally just one foot in front of the other for the entire 4 miles. The runs did get easier. Probably found the 2nd run hardest. Thursday now and just about feeling normal again.

When I’m fully recovered (been out with tendinopathy nearly a year) I’d love to try this. Cracking effort from Nixon, putting in an absolute shift. I’d also buy an “above average” shirt since you mentioned merch!

LOVING YOUR EMPTY CLASS ROOM.. inspired by your approach, and been for a walk up the hill. running not an option yet. from a end of the road quarter of a mile, to one walk to the top of the hill is one mile. and for the two return. pumped. thanks for the kick up the butt.

Excellent videos man. I have been following Goggings for a few years now and found your channel about a couple of weeks ago. Have your videos on pretty much all the time when I am training. Stay above average!

Congratulations it’s a tough one. Being a fisherman who’s used to sleep deprivation I still found that to be the toughest part. Everesting on Zwift next?

Lincoln looks so happy to get in on the action. Haha well done!

Fantastic film Mark and the only challenge you have done that i can claim to have done too. Lastly ear i ran the 50 mile Goggins. You are right, time flies between runs, sleep and meals need planning. I found really varying the terrain helped, even a short drive to the moors one time so that every run was a different experience. Well done and great films, really fun and motivating. Keep them coming

Epic work. Great video. Did this last year and the sleep deprivation is brutal. The running is actually the easy part. For me it made me realise I will never complain about what time I need to go out for a. Run. There's now excuses. Good luck on your next challenge

Great job Mark, I could literally see you hit your runners high 👍

Wow man that second 4 am run monologue was something!

The quality of your videos just gets better and better, and congrats on the website launch! I ran the 4x4x48 this year again, but I want to tackle a 100km later in the year so I figured I’d increase the distance to 8.5km per run so I could get a taste over the 48 hours, it was interesting. If I ever hear “empty classroom” from anyone in regards to putting in work I promise to make sure they know who coined it! All the best.

This is now become my favourite you tube channel. No BS just a normal guy getting fit, challenging himself, & having a laugh along the way!

i love nixon. what a champ getting up at 4 am and just running with you. No question. haha

Your dog running a 8’ mile pace is amazing

Always look forward to watching your videos, such an inspiration 🏃🏻😀

Inspiring! Thanks for sharing your experience! Stay hard!

Kudos to you, your wife and all your dogs on an amazing 48hrs. You could give poor Jefferson some respect next time! lol

I now imagine you have a shelving unit in the garage full of shoes, and another one next to it full of small dogs

I completed this this year, I could only convince my dog to come out twice. He loves running but he does not like the dark. I enjoyed the challenge. I learned a lot about myself...and about adrenaline! I walked 2 legs as I couldn`t physically run but got the distance. I don´t think I would do a 4x4x48 again in a hurry but a 4x4x24 I can see myself doing a few times a year. I love your empty classroom analogy. I will remember that. Thanks for sharing x

Great content Mark and thanks for giving my chuckle muscle a bit of a workout.

Definitely one of your best Mark. Fantastic effort, brilliant production and music and thank you for taking the time to explain in depth your thoughts and feeling between the runs. Awesome!

I did this a couple years ago. It was great. My goals were to run every step, and Avg under a 10 min mile. Reached both. Last year I did a 1x1x24. Even miles were just running, odd miles I ran with a 30lb log.

Congratulations! Makes me realise how much I miss having a dog in my life.

Absolute legend! :) Good job! “Burning with determination to even out the score….”

And the dogs going like a fucking train 😂😂😂 fantastically funny 👍

N❤️I❤️X❤️O❤️N He is my favorite dog on RU-vid!!! Way to go, what a good boy 👏

Great video mate very clean and well produced. You are a phenomenal speaker too. Things I have done in past 3 weeks because of you. Ran first park run in 5?? Years. 26 mins. Dropped 4kg - now down to 100 (6’1”). Got back on my road bike. Did a 70k mountain bike last week. Started going to the gym. Bought a ‘because I was Inverted’ Top Gun T-shirt. And a I’ve spread the word about your amazing channel down here in NZ. Will be watching yr ironman journey closely - I’ve done 5 fulls in a past life and they are hard.

I’m so glad I discovered your channel a couple weeks ago 🙏🏼 I’ve never thought someone would be able to relate to some things re: nutrition & overeating!

Nixon makes for a great companion on your runs. How did you get him so enthusiastic about running ? Would love to have you make a video just on him consisting of some some pointers that others might take way to groom their dogs in a similar manner!

Great job!! I'd consider this on the bike instead of running (indoor trainer once I get real tired so I don't crash). What do you think would be an equivalent distance on the bike every 4 hours?

Long time watcher, first time commenter! Love your content it has been really useful for motivation lately. Thank you for doing this challenge in support of these charities, I hope everyone who watches can spare even a small amount, it really makes a difference.

38 seconds into the video, and I knew it was going to be another good one. Good job, an excellent video once again!

Awesome work, should make a short of your empty classroom thinking. A few people I know that need to hear that.

Слава Україні!

The scene of you leaving your garage with Nixon was priceless on so many levels. Love the humor...love your stoke....Nixon is a hero! Hello from my empty classroom in central Austria!

So many great moments in this video. Love the run with Lincoln and the empty classroom metaphor! Nixon is a beast.

Came across your channel while looking at Fenix 7 reviews, which I ended up buying. Been binging your old videos, and I'm motivated to enter a Spartan run now and just push myself harder overall. Love the content, keep it up!

Great video Mark very inspirational. Your upping the quality of the content all the best mate .

Loving your work Mark. I’ve watched most of your videos while I’ve been cooped up at home with the ‘Rona. Can’t wait to get out and run when I get released from isolation. Sounds like we have many of the same binge eating problems, I’m definitely gonna try some of the things that have worked for you. I look forward to wearing one of your way too tight ‘above average’ t-shirts

Respect for you and your dogs 🐕. I think you are a inspirator and motivator!

Man I love your videos! So inspirational and just awesome! We have frequent power outs here in South Africa, I got caught recently during a solo run at 8pm and also forgot my headlamp, then a power outage happened. It was completely pitch dark and of course no streetlight. Fortunately I had my Garmin with nav otherwise I would have been in trouble!

New subscriber! I’m more of an out of shape weight lifter with various injuries. I am in the process of reconfiguring my workouts for new fitness goals. One of my chronic injuries limits my ability to run but your vids are inspiring to go riding on the road bike and fan bike at home! Happy to come across this channel!

Thanks for the post...first visit to your Chanel....great work well presented...uplifting....and the dogs are great guys too

Really great video Mark, hilarious and makes me want a Parson's even more! Well done on the effort (all of you), extremely motivational, informative ....and funny! Great cause, I'm donating. Looking forward to more content on the website. Thanks Goggins is funny, but in a completely different way. Stay Hard

Awsome! Might have to do this next week thanks for the great videos

Bravo sir! And so many great motivational words spoken! Keep smashing it!

Fair play on the motivation speech mid run! Loved the empty classroom analogy. And you made it look easy pal well done.

Fantastic Job Mark, inspiring as usual brother . Suffering for the mind and spirit. Love watching you and David! Great since of humor for sure on your show. Peace be with you 🙏💯🥵💯❤️💯
