Conner Mantz, Clayton Young, Galen Rupp, Sam Chelanga Chicago Marathon 2023

Slow motion video running form comparison of the top American men in the 2023 Chicago marathon, including a comparison with Kelvin Kiptum and the effects of super shoes on running technique.
The broadcast coverage of the marathon didn’t show much of Conner Mantz, Clayton Young, Galen Rupp, or Sam Chelanga, so here is your chance to get a good look at them at the end of mile 25.

If you have any of the issues discussed in the video, here's my best free resource to help you start to learn how to run without arching your back for a longer stride, a better forward lean, and better performance overall. It will also help you lengthen your right side better and beat the right-hand-forward situation I described..

Do you run in super shoes, and if you do, have you noticed whether you arch when you take off?

[@markjohn9615]

Yes, I think so.

[@laurainthehaute918]

I ran in a “nylon” plated shoe with a rocker (Speed 2) and used it for racing and much of my training. I believe it lead to an injury and a vulnerability I’d never had in 18 years of running.

3:16 exactly 5 years ago in this same race, Galen ruptured his left Achilles tendon due to Hagland's, and had reconstructive surgery. Crazy to think that after all the rehab he did, he's still compensating 5 years later.

[@jgt1120]

he was dealing with that injury for a while before he had the surgery as well

[@abigrunner209]

It would be an interesting analysis if you could do an earlier comparison in the first 5k (fresh form) and compare it with the 25th mile fatigued form.

[@paulbbareil6080]

Really interesting! Thanks for that analysis.

[@Active4life_run]

Finding this comparison with the super shoes so interesting!

[@snousain]

Have you done a video like this for Kipchoge?

[@jgt1120]

Rupp really loves to plantar flex, Clayton Young has also had that arch his whole career

[@Rudolph_Fischer]

8:33 Jan, in your observation, why are so many runners shorter on the right side, making it harder to lengthen, and causing an overreach of the right arm? Is it b/c we train our whole lives turning to the left running around elliptical tracks, and almost never run reverse direction on the same tracks?

[@balancedrunner]

It's anatomical, @Rudolph_Fischer. You even see it in runners who've never run on a track. It's nearly universal, and involves the abdominal organs, the diaphragm, the eyes and ears, and probably other body systems as well.
