It's funny, been competing for many years but only thought of this recently.
During the ironman i am in aero position most of time, then i wondered. Of course the wind is a huge factor in speed. I was riding the other day and on flats was going only 23km/hr and on way back close to 50km/h. Is there any advantage of been out of aero position with wind on back and using yourself as sail. Of course always aero into the wind.

any thoughts.???

thanks

I think so. I've heard several experienced distance cyclists say that you're better off sitting up with a tailwind. For me, I have wrist injuries that make the aero position way more comfortable, so I can't sit up for long. But I bet there's a benefit when the wind's at your back.

Have been hanging out with a number of ultra cyclists recently and this exact question has come up ...
These are folks who've done PBP (Paris-Brest-Paris), Furnace Creek, Boston/ Montreal and think that sitting up in a tail wind does give a benefit...one woman even admitted to sitting up and holding her unzipped jacket open! (worked, but proved to be way unstable.) I was out for a long ride yesterday with a partial tail wind...seemed to work...but as soon as the wind shifts to the side, or you zip around a turn... the bennies decrease.
I'm just the opposite of you Mom...can't get down in the aero position...gel tainted acid reflux (gack!)

This exact question came up today at a race. We had about only a 2 mile ride on the causeway from an island that had about a 15-20mph tail wind on the way out, and just about everyone was not in the aero position. We all were in aero heading back in though!

I think it matters whether or not the wind is going faster than you are. So if it's a 20 mph wind and you are going 23, you're better off in the aerobars because you still have to cut through some air resistance.

Exactly. It's just physics.
