Hi! I just bought a bike last summer, and it was the first time I had ridden in at least 18 years. I really pushed myself to be able to ride 20 miles or so. Unfortunately with the long winters in WI, I feel like I'm starting all over this season!

My DH and our group of friends are all very good riders - they can ride 35 miles and it's leisurely to them. I've only ridden a few times this year (will be able to do so more now that I'm on break from grad school), and they were 8 mile rides. I average around 13 mph, which I know is slow.

Does anyone have tips on what to do to gradually build myself up? I'd like to be able to ride 25-30 mile rides and keep up with everyone, but I really can't do that yet.
