He's basically cruising at the all out sprinting pace of the average guy.

Growing up in Mombasa Kenya,we could never win athletic competitions against the students from Rift Valley. I remember our teacher telling us that Mombasa being at 0m below sea level,our red blood cells are not the same as the people who have grown up in the highlands of Kenya who-due among many factors but not limited to- are more adapted physiologically endure running long races due to living at high altitudes.

And that is why,most Kenyan runners names start with „Kip-something“ or „Chep-something“ because they mostly come from the same area of Kenya.

I don't think I could do a sub 2 hour marathon on my bike.

Kipchoge was pointing at the crowd with a big smile on his face. Doing it is already the most impressive feat in the sport, but making it look easy is just beyond comprehension.

The fact he ran that fast for 2 hours is wild and unthinkable to me 😳

He ran a 100m in 17 seconds 420 times, that is so freaking crazy if u think about it

It's just actually insane... I cannot even begin to try to comprehend running 26 miles at that speed.

I was going to skip directly to the actual kipchoge's pace part after this video got on my recommended, but not only it grabbed my attention to watch it fully, but also was really motivational and showed me some things about running that I didn't knew. Good job!

Kipchoge's last kilometre was a 4:12 mile pace, or the same as the women's mile world record. At the Berlin marathon just days back, he was running under 3 min kilometres. The last km was done in 2:54 !

I worked as photographer for a Charity on London Marathon 2018. I was 1 mile from the finish, just in first row. He was the first to pass in front of me, so close that I had to move back quickly while photographing, otherwise I'd have touched him with the tele of the camera. What I found astonishing, looking at him, is that I had the feeling he was not running, but floating in the air (he was so light in his action his feet didn't seem to touch the ground). Furthermore he was fresh and relaxed as he had just started the run and (yes) he was even openly smiling; his action was absolutely effortless. An hour later started arriving the bulk of 'normal' runners; respect to him, they looked all so tired and clumsy (it was also very warm) that they gave me the impression of a group of people just escaped from the Sahara desert.

My 6 year old is closer to me in running than I am to Kipchoge.. When I let that sync in for a moment, I need a hard liquor.

As a moderately good runner (decent in NCAA division 2), I can assure you that Kipchoge’s pace is ridiculous. I can do ~1 mile at his marathon pace, barely. Basically, he can hold that pace for 26-27 times longer than I can. The man is a machine.

“Chase down a scumbag speed” almost had me choke on my coffee 😂 Loving your videos Mark!!

In a world of 'look at me' videos it is so good to have this genuine appreciation of  the scale of Kipchoge's insanely brilliant achievement. Thank you!

8:43 Haha "my chase down a scumbag speed", love it!
I once saw a TV reality cop show where they did precisely that: a cop was being interviewed when he witnessed a handbag theft & run. He casually says "no worries, the kid smokes pot all day, run behind him and should catch him in a few minutes". And after a gentle jog, he found his thief hiding underneath a car, all winded. Hilarious.

I am from Kenya and seen Kipchoge and his training mates run and trust me that pace is CRAZY! Kudos to the attempt.

Calves are still burning a few days on from trying this challenge 😁

Your progression from 40 min for 5k to 19 is superhuman

It made me feel so good when you recognized the hard work I’ve done to get from a 12 minute mile to an easy 9min40.  Very motivational.
