I can vouch for that. On saturday I did some slower speed running behind a triathlon field. Originally I was thinking how they would go in warmer weather but I did not feel the heat. Too much hot air blast can make you feel less comfortable, while retaining a bit of moisture on the skin to evaporate seems more comfortable in really hot weather.
They would get in the road of highway pegs. When stretching my legs I had to move them a little bit further out..or
