Trying The 10,000 Calories EAT And BURN Challenge | As Done By Will Tennyson 

Love this video. Entertaining and educational.

"Her body is just far better at taking a hard pounding" 🤣🤣🤣 thanks for that Mark

“A Garmin stress chart that indicated I should just walk towards the light ” had me on the floor 😂😂

I think a lot of Mark’s humour flies under the radar, I love how he often refuses to grasp the low hanging fruit.

"I assumed it was just the muscles that i worked very hard that day, which given that included my heart, i figured death would soon follow" had a good laugh at that one

I watched this drunk. It was like a comedy sketch. Mark is a comedy genius.

"Americans know a thing or two about consuming a load of calories" - another banger 😂

"If the chocolate egg had its own pronouns and was fleeing persecution from a foreign country then the Daily Mail would be even more horrified" That made me laugh, spot on with the analysis 😂

As someone who's 5'3, Mark just cranking out 1000 calories here and there in a hour is mindboggling.

I love it, "typical youngster". The diligent, experienced athlete knows that the crux of this challenge is the gigantic chocolate egg lol. Well done as usual, Mark!

I like that this isn't Will's comedy like a lot of people are prone to do when they watch other creators, your own style is freaking hilarious and pretty well thought out

Loved the video. My take away is that a collab between you and Will would be comedy gold. Hopefully the universe lets it happen at some point.

Really fantastic video. Maybe your best yet? The puns were spot on. The challenge ridiculous. Well done guys! 👏

Mind-boggling. I usually burn at best around 3500 (active and resting) on a particularly active day. 10,000 is nuts. Well done!

I don’t think I’ve laughed so much, this guy has an unbelievable sense of humour. Top bloke. The ending was incredible 😂

The effort you put into your videos is mad! I’m not even talking about the physical stuff. 😂 But just filming in public and editing a piece of work like that is fecking relentless and keeping a clear narrative throughout too. From one content creator to another you are a beast 💪🏻

If you and Will got together I dont think I'd be able to breathe - you two would be hitting us left and right with dad jokes lolol

Brilliant one, from the challenge in itself to Jens “really” and “entertaining the wife”, your vids were always excellent and they’re getting better

Loving this content Mark- thanks for still putting stuff out on RU-vid!!!

Another fantastic video Mark. I truly look forward to you posting. 😊

This is a brilliant video. The best thing you’ve done to date Mark! 👍🏻 Has no one spotted the perfect pause between ‘tossing’ and ‘turning’ yet?

Stunning effort Mark! I’d call that a victory, I’ve only ever seen people do the “easy” part of this (the eating). Very inspirational 👏

Great video! Love the quality and effort that went into making this video along with your unmatched humour. I felt sick with exhaustion and fullness by the end of this video. Keep it up!

It is not often that I subscribe after only watching one video. This is one of those times. You're a certified legend, sir. Keep up the good work!

can't believe you said "jen can take a hard pounding" with a straight face lol

"I can easily see how this challenge is failable" that was when Mark hit his low confidence point... Absolute masterclass! You did a great job at conveying your message and showing everybody how it's done (and confidently I'll add)

mate, this is the first video of ive ever watched from you and you are just a character! youre an absolute pleasure to watch and now I am currently binging your videos, glad I stumbled across your channel, all the best from down under! :)

Mark, I've seen most of your videos, this is up there with the very best. The conclusion at 23 mins onwards is genuinely hilarious, so well written.

Big Will T fan and enjoyed his attempt at this challenge. Thanks to youtube algorithms now discovered this channel and I'm very grateful. Epic twist at the end!

can i just say how much I LOVE your videos?! stay awesome! As a masters age group (40yo woman) competitive cyclist, I understand your struggle trying to get all the calories in and the fatigue/cramping from all the work.....not easy, so I applaud you for taking it on!

I’ve gone of these videos a little lately but absolutely loved this one. Great job

Now that I’ve seen the video in its entirety, it’s brilliant! Thanks, Mark, for doing this work and sharing it, along with a healthy dousing of your humor, with the audience. Just keep stayin’ alive, young man.

That was incredible mate, what an inspiration! Well done 👏

Instant fan. Well done for trying! You almost had it. Your sense of humour is next level. 👏👏👏

Bonkers, I loved it. Good effort & thanks for a very amusing video! When are you going to do attempt two?

Man I love your sense of humor! So subtle and hilarious! Great inspirational video as always 😊

Mark’s final joke had me in tears. Perfect abrupt cut.

great job Mark, you did very well! I tried this a few weeks ago and got to around 7300 calories burnt by 7 pm (but wasn't counting 'resting' calories) but I had only eaten about 5000 calories and felt really full so I gave up there. In hindsight I'm annoyed that I gave up instead of trying to push through but I am already planning on what I can do differently to complete the full challenge another time and you gave me some ideas as well!

The commentary is the best part. Love your videos, and this may be your best yet

Hilarious the best 10k challenge yet well done! 🎉

That was the funniest video in some time. Laughed out loud on atleast 3 different occasions

Your sense of humour KILLS me. But also, PB & J is a pure delicacy of the people and you should definitely give it another shot 🤩

Love ur humor and editing style!!!

Great video Mark, one of your best. I really enjoyed it. I thought you had it in the bag! You did really well just to get that close.

Hey Mark, I have commented previously that I was initially disappointed in you moving away from the 'Free' RU-vid platform, but I'll be the first one to say that I apologise for expecting less from you and wrongly anticipating that your channel would not motivate me to do more exercise for a better life for myself and my family. Thank you for these 'still' regular uploads VS the paid subscription. Thank you for your efforts!!!

Don't know what I enjoyed more, you taking a dump on the daily mail, or the content of the video, well done!

WOW, what a great video!! I saw Will do this challenge and Browny and I really enjoyed your take on it. New subscriber! Great job!!

This is a really good video mate!! Good work.

Definitely the right strategic plan - lots of sustainable cardio, relatively normal (minus the egg) food consumption, with a binge meal planned for the end. As you said at the end, more hydration/electrolytes would have helped. I also wonder if starting the clock after a prolonged rest (mess your sleep schedule up for a few days, then sleep for about 15 hours, then stay up for 24 hours straight for the challenge) would help? A few extra hours to spread out the intensity of the cardio may have helped.

Dude's dry humour is very entertaining! Stuff like .. "Americans know a thing or two about consuming a load of calories" .. "entertaining your spouse" .. "Her body is just far better at taking a hard pounding" .. and more xD The amount of chocolate would get me worried towards digestion lol

I thoroughly enjoyed this video and its my first time visiting your channel. Loved the challenge and your dry humor tops it all off. You're motivating me to do one of these challenged myself but I'm nowhere near as active as you.

Crazy!!! Love the vids man!

Bloody heck you must live weirdly close to me, I can't think of anything funnier than seeing you attempting this challenge whilst on my morning run 🤣 Brilliant video ✌️

Possibly one of the greatest fitness challenge videos I have seen. 😂

Genuinely loved this, great video

Realy like how you shared your planning for everything you did

I'm dying laying on the floor here. This man is gold! Garmin said I should just walk towards the light :))))))))))))

Hi Mark Lewis, here’s a little something from me to show my appreciation for the good stuff you put out. Keep it up man! ❤️

Another banger of a video! Keep up the good work!

Well done. I see you as a winner, since you beat the most difficult part of the challenge👍. You rock!

Actually pretty impressed with the results of this. Will definitely over-prioritized the food a bit, but both of you guys are good TV in your approaches.

I'm not even finished with the video. But I love it. Really fun and easy to watch

Love all your videos but this may be my favourite. Had me laughing at your sterling efforts all the way to 23:05 and then “Oh no - that’s very not good”. Glad to see you recovered and you’re better now. You’re nuts (in a good way) to try such a crazy challenge. Keep up the great work. 👏👏👍

Watched this video more than a few times and I never cease to LOL multiple times! One of your best (in a great back catalogue!).

I never met anyone who hated swimming 😂, this was very funny and entertaining to hear your honest ideas. The ending was wild tho

This looks so hard. Can't imagine how you were feeling in the afternoon with hours left in the day. Amazing job.

I wasn’t expecting that ending!! Brilliant effort you smashed the hard part!!

Love your channel man !

Don’t know why the Staying Alive clips have tickled me as much as they have but your movie clips never fail to deliver Mark! Good work fella.

I challenge anyone to watch Mark’s videos and not laugh or learn something new regarding fitness and health…..And how to give your offspring the teasing they probably deserve. 😂😂😂😂. You’re the action hero we need Mark!

Your best video by far... glad you're still on RU-vid...👍

loved this vid my fav from you so far!!

this was a very good and different approach to what I've seen with these challenges before...they mainly concentrate on the food and then play catch up with the exercise, but we all know it is far easier to eat calories than to burn them!

great video as per usual 👍 most impressively you seem to have finished the challenge and then done an additional 48 hours without eating the other half of the egg ...

I thoroughly enjoyed this one! The will power you have is crazy!

Hey everyone, which Garmin sport profile should i use for Misc stuff like kettlebells, pushups, crunches, pullups etc. I dont wanna choose a different sport for everytime i switch. is there any 'all' sport profile i could use? thanks

May I recommend the 24h Le Mans Velo as a soloist? 17000 cals burned according to my Strava track. As Dr Hutch described it, such events are “an inconvenient eating competition”. But i get the point here. To do huge endurance events, you need to train for fuelling throughout, and during, the whole event. Its not trivial.

That's some impressive calorie burning. Now just to wait for Coach Greg's inevitable reaction video

This has to be one of your best Mark. Pure quality 🤣🤣

One of the best videos yet. Brilliant! Laughed out loud a few times! 😂 👏

I came for the down to earth personality and challenges, I stayed for the cracking banter! 🤣

I don't care what anyone says, I consider this a victory. We all know you'd have eaten the remaining calories if your muscles hadn't staged a mutiny against you, and you knocked the REAL challenge of the day out of the park. I can't imagine the agony, I'm glad you're okay at the end of all of it.

This is amazing great video just subbed ❤

love the video, great fun to watch, my record is burning 18.000kcal in one day when i cycled for 24h crossing Portugal North to South (740km with 9000m elevation), not sure how much i actually ate, but i guess around 10-12.000 but mostly liquid energy drinks as nutrition :-)

24:20 - I like how the Garmin says “too many consecutive days like this _can_ exhaust you” 😂. Amazing effort and excellent video!

Definitely educational and entertaining. Was looking for the top exercise tips, was not expecting the hilarious zingers😂

First I've seen your channel. Subscribed immediately! Love the video

Classic video, brilliant script. A return to stand up beckons.

I'm sure there is a chocolate out there that's fleeing prosecution with its own pronouns. The daily mail just isn't looking hard enough

This was such an entertaining video. You have a fantastic sense of humour.

Highly entertaining upload. Thanks man.

Excellent. I found easiest calories during recent med treatment when I was told to put on weight was creamy ice cream (1k for a 480 mil tub). Extra thumbs up for the Daily Mail gag as it’s a filthy rabble rousing paper I wouldn’t wipe my arse on. Bravo.

I always wonder how accurate those calorie tracking watches really are. For example on a day i take my adhd medication my heart rate will be higher, so the watches think im burning a lot more calories, which definitely isnt always the case

Had me chuckling all the way through. Great video.

Have watched a lot of your content but this was a cracker, keep it up Mark 🤝🏻

Just thought of something. The "rest calories" of the Garmin are based on your typical daily calorie expenditure for your height/weight. But during the challenge you ate a lot more than usual. Your body had to process all this food, it must take quite a lot of energy to move several days worth of food around and digest it. I wonder how many more calories you actually burnt.

5:16 - how on earth did you manage to keep a straight face? :D

what a twist in the end there :D great work! and fun video

Great content as always. I ate way too much even though I was very active without "calorie counting" and portioning I never would've dropped 40lbs and kept it off for over a year. Exercise was a great habit. Once portioning and understanding calories entered the picture I found the results I wanted. Keep on trucking!

Gee I fail to get 4000. It’s so difficult. 10k seems like a nightmare.
