I'm glad someone asked this question because I've been wanting to get faster but it's getting harder to do so. My avg is about 20 mph by myself, but I've been riding with a superfast group to gain speed (I usually get dropped but I've realized now that I've been getting dropped later and later). I need help with gaining strength on hills. I do fine on rollers but if I want to race (and most races are planned north of me) I need to do some climbs. Problem is, I live in Orlando so hills or anything resembling hills really don't exist. I know to train into the wind but there's very little wind right now. What do I do?
