With a lot of modern bikes some consideration might need to be taken for the wheels but I'll tolerate 30mph winds on the local path. The kid and I went out one time where we were doing ok with our 27mm and 34mm deep rims although you could feel the wind trying to push them a bit but the pair that were trying to train on their Tri bikes were seriously struggling and we watched them get knocked off the path. And my steel frame might not be too aero efficient for racing but it also shrugs off real cross winds that could catch something with flatter profiles.
