I'll fight a headwind up to 25-30 mph, but I hate crosswinds!! Both are a struggle; to keep pedaling, to keep your bike straight, to mentally not give up. Headwinds are simply a struggle of wind against pedaling power to keep one moving. Crosswinds test your control of the bike, your stereing, your balance, your strength, your reaction time. Much more challenging, IMO.
