I trained like a TRIATHLETE for 24 HOURS | 100 mile ZWIFT ride + Marathon! 

The physical abilities of small terriers are just awesome. Those of Nixon in particular. What a heart-to-blood-volume-ratio he must have! (You also made an effort, which is nice.)

I'm glad you carried on even though you got dropped due to unfortunate circumstances. BRAVO!

I'm 10 minutes into this and I literally can't stop laughing. 'The group's buggered of...'

Absolutely love your channel! I was not a runner (powerlifting and bodybuilding) and am a heavier “athlete” at 212lbs @ 5’11 and 34 years old. I started my running with a dismal one mile “Run” at 11m27s. It’s been a month and a half of hard training, but I’m now at a comfortable 24 minute 5k. You’ve been a constant source of motivation, along with Nick Bare, on this journey. Thank you for being above average and pushing me to greater results than I could have imagined. I am now a runner for life and look forward to most of my runs 😂.

Very inspiring content though! I rode 100 miles on my road bike in summer on road and it was brutal in the heat and managing all the nutrition aspects. Take my hat off to you for staring at that screen for over 4 hours 😆

Really enjoying your videos. Normally pretty active, but I'd been in a rut for several months. But after watching a couple more of your vids last week, I got up early on the weekend for my first run and loved it, ditto mid week, and I have my first park run this Saturday. So thanks! But mostly I've been meaning to say how epic your wee dog Nixon is. I can't believe the distance those little legs can cover, wow! He must be so damn fit!

Massive effort on the bike Mark it’s so tough to lose touch with a pack and keep yourself motivated but you were a treat to watch.👍

Brilliantly put together, brilliantly run, very motivational and inspiring and absolutely class Spinal Tap reference Mark - superb!!

That classic Spinal Tap reference is chefs kiss..even better in Dobly 🤘

Perfect content for 30 minutes on my rowing machine. In a hot shed, because heatwave. Will drink enough water now 😂

Pity the IM thing went sour, I really enjoyed this challenge. Nixon just casually running a marathon 😮, I think even Molly, my border collie, would be impressed… Actually, funniest thing was discussing Nixon & Jeff’s “choice” of gear 😂.

Hopefully some one has already mentioned this (or you have learned it on your own since) but you can enter Zwift settings during the ride just fine; but when you go to the pairing screen, your avatar always stops peddling. (This is actually a quick way to switch bikes during a ride. Pressing A on the keyboard brings up pairing screen, which stops you, so you can make a bike change faster. I just did it this past weekend during the Gran Fondo event before entering the Jungle circuit.)

brilliant video - loving the content. Would be great to hear a story of your fitness journey from 330lb and some of the lifestyle changes you made to get to where you are!

Great information again Mark, thanks for sharing. Now you have me interested in the Fenix watch although I don't believe I'm active enough to justify the expense. Any particular reason why you didn't wear it during the 100 mile bike ride? I've experienced the same HRM issue with Zwift and it drives me bonkers you can't tweak a setting and then return to your ride seamlessly. Above average effort, to be sure. Love Nixon, hope he got a few treats post run!

Cracking as usual mate. Nixon is an absolute machine! Cracks me up. Not just doing it with you, actually pulling all the way. Also. Is that a Capri I spy in the background?

Amazing video Mark 😄 hugely entertaining as always and brilliant insights all the way through. Think Nixon went full husky there from time to time on the run for you 😉 love the new intro also - superb 👍

The 2nd 1/4 of my run is always the hardest. It's knowing that you've done a lot, but you're not even halfway done that gets me. Once i cross halfway, i can tell myself I've got this in the bag.

Holy crap your dog is a beast, 4 hours straight!

Lots of group rides have sweepers that help out dropped riders , always worth a shout out if you’re dropped , a few riders normally drop to help you back on

I just looked over at my cats and asked them if they wanted to go for a run. Weirdly they said “no” I guess today is a rest day. 😂

Very interesting. Thanks for the video.

Great video yet again matey! Finally ordered myself a Powerdot after hearing good things about them. Would be great if you made a video on them. It was an expensive investment but hopefully a worthwhile one. 👍😁

Definitely above average.

Dude, you're a machine! We all have to step it up

The difference between triathlon training and just running, biking and swimming: brick sessions.

Working through all of your videos and I've gotta say they are enlightening, motivating and humourous all in one. One question- how does Nixon consume his water on the run? Do you spray water from a bottle into his mouth or do you fill a bowl. Does he eat during the long runs? Thanks!

lol! you are so funny! I really like your content buddy! cheers from Canada

Loving your very entertaining videos Mark. Tremendous effort on your part sharing all your activities. I’m nowhere near your level but you are a motivation for me to keep on with my little exercise regime Cheers !

Great video, actually pretty inspiring. Especially whenever you talk about the old you starting to run and where you are now.

"we are having a conversation now" Lush, I miss having dogs. :)

Such a cute puppy

Awesome effort!! You have come so far!! Chapeau!

Great video as always! Random question... when you stop to give a drink to the dog, etc, do you pause your timer? Can never decide if it's cheating. Thanks for your help.

The algorithm kept this on the “watch next” list for the past three weeks and finally I relented and watched. I would have viewed this earlier but was wondering if YT would eventually pull this from the top of the stack. Now, I’m wondering which episode will be next!

Love Nixon!

Have you soaked in epsom salt water? It helps a ton.

Really enjoying your content mate 👍

That dog is very fit

Hello mate could you please do a video about the best place you have been In uk for outdoor stuff running biking swimming etc that would be fantastic cheers.

Hi Mark, you say your first Parkrun was a long time, what was your first time? Started a few weeks ago and it’s been run walk run walk here too! Keep up the great work on the channel, very inspirational!

you know a triathlete swims right?

Hi Mark. I've recently found your channel and have been binging all your video's. Have you tried supplementing with Glycerol to aid in reducing dehydration? I found that to help me. But we're completely different size and shape.

Sneaky spinal tap references? Shame I’m already subscribed, or I would do it right now, but I can be... none more subbed.

Depends which triathlon... : ) A sprint .... thats a short one

I will complete the ironman 70.3 competition at least once in my life!

Great vid. Don't forget you can send messages to the group. A cheeky message asking to wait 2 min might of worked when they stopped. But fair play 100 miles is a long long way on your own. And 119 position is better than average :-)

nice, maybe should have stuck something in the group chat in zwift to ask then to wait firm you maybe

Did Nixon run that long with you? I'm wondering how long it would take to train my dog to run as much

Zwift is weird, interesting. Thanks

What’s the temp in your garage? January in Texas has my garage at around 50 degrees which I warm up to around 65 to start. No steam for me. :)

I think the word would be "Triathletic". Feeling triathletic. Yea. Also you need to choose the climbing goal asap and begin the accumulation of altitude to unlock the Tron bike.

respect.

please go for a better than average Ironman!

Considering you only started road riding in the summer your riding at an impressive wattage, how does your current FTP compare to when you first started riding?

Sorry sent previous email ,,,11 stone 10 ,,what would u say is a good watt figure ,,to average over an hour ,,appreciate time

Pancakes🎃💪

… where’s the swim? Did i miss it?

Was that little piano bit "Lick My Love Pump" by Spinal Tap? Edit: It definitely was.

Mate you forgot to swim about 3.8km lol.

Hi Mark. Great and interesting video again 👍🏻. I have just started doing short runs (3 miles) during my lunch break at work. When you first started running, did you ever feel pain or discomfort afterwards? Especially the next day. I can really feel it in my hips and sometimes sole of my feet. Just wondered if this was normal due to not being used to the impact etc? I have literally only just started so could it disappear if I continue or am I destined to only ever ride a bike 😆. Thanks.

1st to see vid ........get in

Curious, do you ever do any hill biking?

Actually would have made sense to bike without drafting, as im a triathlon you are not allowed to sit in the wheel of the person in front

chive and herb with nutella bagel 😮😮🤣🤣🤢🤢

😊 plot😊😊

the dog is more active than i am

Hi Mark, before you became above average with a HR at rest of 39-45, what was you resting HR? Feel like I’m doing something wrong as I can never get mine below about 57-63 at best. Greg videos, love the comedy element as well.

No swim? 😂

My rule of thumb is 1 L per hour of fluids and 80-100g of carbs per hour.

@ Mark Lewis, is that a watt bike ?

no drafting in ironman

It's "tri-ath-letic-ious".

Hi Mark, your sound seemed very low in this video.
