At 12.7 MPH, would more aero clothing (and race numbers) affect the runners? Over 2 hours, these guys are down to 10 to 30 seconds each time the record is broken. What if they were in a time trial FastSkin?
I’ve noticed that runners put pride in wearing flappy runner-clothes. Only triathletes seem so run in skintight materials (and love it).
This paper predicts about 5.7 seconds advantage gained over the marathon distance by lowering the resistance of a runner by 2%.

Only triathletes?

Mostly the top males. Females tend to wear much more skin fitting clothes for their runs.

5.7 seconds? They are crazy to leave that time out there. Now how much more would an aero helmet get them?

What if they went topless?
Topless would work for some. Others, well it might not be as pretty a sight as you think.
Why would you want to see a bunch of dudes running topless?

A personal fav.

The next cover of runner’s World:
This paper predicts about 5.7 seconds advantage gained over the marathon distance by lowering the resistance of a runner by 2%.
I find this paper’s abstract odd. It suggests that a 100m sprinter will typically gain 0.01s but in Mexico City (at altitude) he’ll gain 0.08s. Yet the air density is lower at altitude so changes to aerodynamic drag should have lower effect.
The paper is around 30 years old - I wonder if there is any newer windtunnel data on runners in floppy tank-tops vs. a snug tank top and compression shorts.
Abstract
The purpose of this study was to determine the effect of the wind resistance of athletic clothing upon running speed in sprinting and in distance running. Wind tunnel tests of clothing materials, hair, and shoes show that it is possible to lower the wind resistance of a runner from about 0.5% to over 6% by improved aerodynamics. Mathematical models of sprinting and distance running are developed to predict the effect of lower wind resistance upon race times. By lowering the wind resistance of a runner 2%, the models predict the effect of lower wind resistance upon race times. By lowering the wind resistance of a runner 2%, the models predict time savings from 0.01 s in the 100-m dash to 5.7 s in the marathon. This is the equivalent of lead distances of about 0.1 to 31 m. The sprint model may be used to predict the effect of altitude upon running speed. At the altitude of Mexico City, the model predicts an improvement of 0.08 s in 100 m and 0.16 s in 200 m. This is conservative compared to actual time savings. The results show that it is possible to lower the wind resistance significantly by improving clothing or by trimming or covering the hair, and that a small aerodynamic drag reduction can result in a significant performance increase

I think they imply that racing in Mexico City (as opposed to what remains open… maybe sea level?) reduces the wind resistance of a runner by more than 2%, not that a reduction by 2% has a bigger effect there.

Given comments by knowledgeable people here about how clothing is (or can be) more aerodynamic than bare skin, she’d probably be faster more covered up. Actually weren’t track sprinters running in things like skinsuits a while back? Were they outlawed by the IOC?

They even had these skin tight hoods. It looked like some sort of body-condom from Woody Allen’s “Everything You Wanted to Know About Sex But Were Afraid to Ask*”
I think Luke McKenie’s oversized trucker hat added some CdA in Kona.
I usually flip my hat on backwards if facing a headwind. It’s funny, but it makes me feel better anyway. lol
