“I have 4 kids, so when it comes to crushing dreams and aspirations, I’m about as good as you can get” 😂😂😂😂

6:20 props to jess. Putting yourself out there isnt easy. Love her effort. She knew shes not the fastest in the group and still did it and allowed for it to be posted online. Go jess!

Damn as a 400 runner i have respect for all these guys, that lactic at the end is a killer!

That 1:08 1 lap is easy....The breakdown of his marathon into 1 mile, 5k, 10k....***mind blown*** That man is alien.

I know Mark mentions he’s tall all the time but it hasn’t sunk in until seeing him next to a bunch of normal sized people.

R.I.P to Kelvin Kiptum You will be missed, and so young too :( Godspeed on your next marathon in the world beyond ✊🏃

Looks like Jenny did manage to do Brigid Kosgei pace (2:14:04 marathon is about 76.25 second 400m pace), so probably deserves an honorable mention for that.

Crazy to think he runs at that speed 105 times around that track. MAD! Great video - Love seeing these types of challenges.

From high school, I have always had huge respect for 400 runners. We knew it took a special kind of grit to hold it together for a complete lap. Great going guys.

15:09 -- you can see Kipchoge in the background. He completed an easy 5k during the challenge and is on his way to km 6. ;-)

Thank you for acknowledging us below average athletes!

1. your joke about "crushing dreams" is just epic. and 2. thank to jen for standing up to the life guard. being a scrooge is no fun 🙂

Thank you for bringing up that less fast people are doing MORE. I have been working with some athletes who have "unimpressive" numbers, and what I have come to realize is that these athletes are pushing harder than some of the fittest people I have been working with.

This was a great watch. As an erstwhile 400m runner back in school, you could tell none of the participants had run a 400 seriously before. As you say, if you're not a sub 50 sec athlete, the reality of running it is that you're trying to stay at 90-95% of your top speed the whole way round. It's just not possible to sprint at top speed for that long. Also should be said they'd probably all gain a second by wearing spikes rather than trainers (you couldn't pay me to run any distance in Air Force 1s!) Would be fascinated to know how the 11.2 100m runner would do in spikes and with a bit of guidance/training. A sub-60 400m with no warm-up or preparation is really nothing to be sniffed at.

😂😂😂😂😂 “when it comes to crushing dreams…..” 😂😂😂😂😂 As a father myself, I can relate.

The fact that this pace is 5 seconds off the women’s 5k record and he is holding it for 26.2 miles is insane

Bro I was not expecting a 75 out of the first one! That was fast as hell. Props to her for that

This year at 46 years old I set foot on a track for the first time since high school with the goal of running a sub-60 400m. After a couple of months I ran a 58 second lap and felt like dying afterwards :) But of course now I think that's still slow and can do better if I work harder. This video makes me feel a bit better about my time :D

In high school, we ran multiple 400m laps in under 60 seconds for practice with 1 min breaks in between each lap until we failed to be under 60 seconds. After 10 laps, the break times were cut to 30 seconds in between each lap. I ran the 800m, 300m hurdles & 400m. I forget sometimes how crazy in shape I was back then & what regular people run certain distances. I don’t think I could run a sub 60 second 400m once right now & now I’m ashamed.

5:01 'Your second thirty seconds takes you thirty-eight seconds' 😂 Another great video btw, Mark 🫡

"I then tried to charge him £50 for the selfie shot with the KZfaq celebrity" 😂

Mark showing off his great people skills here, very wholesome, entertaining and original video. Love to see it, keep up the hard work.

I now need to go to my local track and attempt this, after watching. Just can't comprehend how you could keep that pace for 5km, let alone 42km 😂

Damn sub 60 was pretty solid, he ain't even look tired

Kipchoge speed is FAST - even for just one lap! Could you match him for 400m? 😄

I'm a pretty tall and heavy guy (6ft, 94kg), and for the longest time running was always painful. I could never run anything more than 2.4km, the distance you need to run for a compulsory military fitness test for all men in Singapore. In my search for ways to reduce the pain, I encountered some of your videos on zero-drop, low cusioned shoes. I got a pair of Altra Escalantes, and running is now more enjoyable than ever! More than shoes though, I'm inspired by your persistence to grow as an athlete and your fitness transformation through healthy habit-building. My running journey was triggered by a need to pass that fitness test, but now I've come to enjoy running and fitness simply for what they are. You changed my goals from hitting a raw number, to becoming someone who keeps a healthy lifestyle, regardless of whether there's a test or not. Love your content, and just wanted you to know that it's having a real impact on folks around the world. Cheers!

This was such a good one Mark. I was excited for everyone. You should do this a couple times a year.

Great content Mark. Good to see some locals being encouraged and for them stepping up. Some speedsters there too. Awesome work!

I wasn't sure I'd like the KZfaq standard £50 wins format, but Mark is such a good and funny MC that it makes it way better than when others do it.

So Mark, who keeps telling us how much he hates swimming was once a lifeguard?😂

It wasn't till I hit my mid forties I realised what an incredible advantage youth is!! This is a great example, young dude who doesn't do cardio in joyrider trainers almost beats older dude who's done an Ironman. 😬

I watched the men’s marathon in Budapest last sunday in real life… I was actually shocked about the speed the world class frontrunners generated. You see the numbers on Kipchoge like performances but you can’t really comprehend until you’ve seen it with your own eyes.

I am 58 now…and if I got around that track in one piece….i would celebrate. But it is mind blowing that a human being could run 68 seconds……105 times in a row….absolutely mind blowing…..what a distance runner that man is !!! RESPECT !✊

Putting this in context, Kipchoge is 5'6” and weighs 115 pounds, does everything right and has trained forever.

Hello again, Mark! Great challange! I've tried it yesterday after my 10 k tempoish run, and faild by 13 seconds, but at least now I have a "target" to hit! Thank you again!

Loving the content, Been watching all your stuff preparing for Hyrox as im a skinny runner and entered the pro division weight so been needed all the help I could get, you may even see me their unable to move the sleds. Keep up the great content

totally cheered me up on a miserable morning - well done team

Absolutely amazing, this channel never fails to entertain … proper good fun Mark and Jen 👍

Love these challenges, keep them coming mark

At 16 on my first year college my coach had me to 6 400 meter sprints with run one and walk one ( but it was more like walk two after a few). I did these in around 58 seconds to 1 minute 1 second. I still can’t believe it as I run a mile now at 15 minutes. Lol. and I’m winded. I’m 70. Lesson here is that you shouldn’t stop running all your life. I stopped and then started again in my late 60s.

loving the little Kipchoge's popping up all over the place, especially in the distance during the intro...great editing.

Very happy that you are back, Seth! So good to see you again! And congrats on the double at pikes peak! 🎉❤👍

Alfie doing it in difficult mode running in lane 2 😂

Me, listening to Mark tell us he's tall repeatedly, in previous videos: Yes, we get. You're tall. I got it the first time, no need to keep going on about it. Big deal. Me at 2:15 of this video: Oh my god, Mark is really tall. Me when Mark meets every participant in this video: God he's tall. So tall. In conclusion, I would also mention how tall I am every hour of the day, if I was as tall as Mark. He's damned tall.

Jas is my favourite participant! Heart of gold! She did it!

I love all your videos, but this is definitely one of my new favourites

What a great video. It's always entertaining to compare non-runners with elites or even sub-elite trained runners. My 16 year old lad is pretty good at all distances from 800m (2:03) up to 5K (16:00) but can still only hold Kipchoge's pace for perhaps 3 minutes or so. The elites are on a level that most people just cannot get their head around. That said, a decent trained junior athlete will absolutely blow away a non runner by a similar margin. For example, my lad ran a 1500m a couple of weeks ago in 4:12 and his last lap (after the previous 2.75 laps) was just 62 seconds. A trained athletes ability to actually increase the pace when the rest of us are dying a death is mind blowing. The reality is that training is only a part of it, unless you're gifted with the right genetics then you'll never get even remotely close, especially for longer distances that are predominantly aerobic. The 400m and 800m are possibly the toughest distances to crack because it needs correct pacing, high aerobic capacity and the correct muscle fibre composition, not to mention a high pain threshold and mental toughness. They are brutal.

"Have you done all your homework Alfie?" 🤣🤣🤣

Well done Mark and Jenna Keen to see you come Down Under for an episode or two… Best wishes

This was a super video, loved it and loved how everyone just gives it a go!

It’s fantastic to see how far your KZfaq career has gone! Been here since the arrival of the wahoo bike 🤣 as a keen cyclist myself you got me hooked and I bought one. Now o literally watch every video posted and listen to Spotify podcasts. I really should become a member 🤦‍♂️

GO jaz GO, she was by far number one in my opinion, what a motivation to see her on that track Kindest regards and thanks from dublin. Michael Weber

Fab video , absolutely love your banter and a big well done to jaz as it takes a lot to put yourself out there and she absolutely smashed it 😀

This is the most entertaining video I've watched in a long time! Normal people doing incredible stuff! Love it! 🎉

Wowwwww real fun to watch. Congrats to all those who showed and participated! Great Mind

The woman who was the second to run in this video, ran her 400 at a pace of 2:11:52 per marathon. Tigist Assefa’s world record women's marathon time is 2:11:53.

Eliud Kipchoge’s pace is scary, I barely comprehend HOW this is real, but at the same time it motivates me so much to push myself harder too, no excuses, because I can clearly see what humans are capable of and while he’s more gifted than any of us will ever be, he still puts some crazy dedication and hard work into his achievements, the ability to run like this doesn’t come with talent alone, and if you listen to the guy, his work ethic and inner zen are crazy inspiring.

Awesome vid Mark, one of your best.

Brilliant! Thoroughly enjoyed the challenge. What a great idea. :)

it's always surreal when someone I watch happens to live in the same area I grew up in. haven't seen Bracknell Leisure Centre in years, thank you for the pleasant surprise

Jenna is the winner here for getting the life guard his well earned 50

Second to last race commentary was too funny!!! GG Kevin.

Awesome challenge Mark!! Way to go

Definitely the most consistently entertaining fitness channel on YT. Cheers Mark & Jen!

Great video, I went on a 25 mile bike ride at the weekend and I was slower than kipchoge's marathon pace. 😂😂😂

400m is a really tough race

Love it! Keep the vids coming

I came for the fitness videos and inspiration. But the one liners and dry wit are gold. Keep delivering the quality videos, we love it.

Yay more power to Jaz! Good job!!

The high altitude training makes a huge difference as do genetics. That is a crazy pace to maintain.

GREAT VIDEO !!! Do more like this.

I love this style of content!

What's your sport? PUB 🤣

Get 105 people for a relay

That was great. I've had the conversation with a few runner freinds of mine about how fast distance runners actually run. We all agreed it was a lot faster than the average person thinks but it was great to see an actual experiement like this. Great job guys & hats off to all the runners.

for my college soccer prior to starting on the team we had to do this (a lap under a minute) and then we got a 1 minute break and then had to do a a mile and a half in something crazy like 15 minutes (which is VERY hard after you sprint like this!). Thank you for the content, sir! brought me back to the glory days.

Next year, a bunch of kids who sprint 400m are going to be waiting there to clean your pockets if you do this again. If I had money on the line, I’d push the distance out to like 1500m, and see if people can just hold 3:00 min/km.

Brilliant, as a Bracknell resident, it was great to see this challenge. Loved it and like you admired Jaz for having bottle to try.

Thanks Mark, that was fun ! Well done to all of you. 👍

The race commentary was gold, thru and thru.

Class! Do more similar challenges for sure! Particularly the Steve Redgrave challenge try that with those Gym Bros!

good vid. drone footage a nice touch

Great video Mark, was cheering on everyone, got me thinking I need to give this a go 🤔

Alfi, "have you done any homework?" 😂😂

40 yers ago in HS we would run 440 yd sprint at around that time. But that was knowing we only had to do 440 yd. I can't imagine that pace for 26 miles.

66 and 62 seconds is really fast! But how fast can Kipchoge run 400m? 55? 50? sub 50?

Enjoyed that great video.

Well done to everyone all did amazing and for mark for putting the challenge on 👍

Love this content Might be time for a Mark Lewis track classic like Nick Symmonds does. Put some field events in there as well. See how far people can put a shot compared to Ryan Crouser etc

This is pretty amazing. I have always been blown away by that pace. However, I think that what this video shows that is more impressive is the WR for 400m. Since you are asking people to run 400m as fast as they can,

you're really good at motivating people.

This is awesome; great idea for an athletics challenge! 😀

The 200m mark is 10m than you say in your video. The 200m mark is where that curved line goes to lane 8. That's why the difference between the first and second 200m in this video are so big. Still a great video!

Never mind all this athletic stuff. How brave are you going to Bracknell with that much cash? Respect!

Hilarious and entertaining, and educational to a degree! Love your videos, man!

When I ran track, I was the jack-of-all-trades guy on the team. I ran everything from the 200m to the 1500m. In order of difficulty, I put the 400m intermediate hurdles, 800m, and 400m as the hardest 3. Getting anywhere close to 60 seconds for the 400m is a challenge. Doing that for 42000m is simply incredible. Hats off to all the runners.

Enjoy these type of things immensely. The Redgrave challenge next? 👍👍

Would do this if only for the drone shot around the first corner 😍 I'd drop dead after that corner in my current running state.

Great video, thoroughly entertaining.

this video was great., informative and funny you gained a subscriber
