I started riding in February with 3-4 mile rides (25-30 minutes) every other day. I had 36 miles in February and slowly increased the miles each week. I set a March goal of 100 miles and got 121. April was 200, and May looks like it will end up around 260. I now ride 10-15 miles 3 days a week and take a longer ride on Saturday (up to 40 miles now) with Sunday reserved for just a slow cruise of 6-10 miles. While riding with the wife this Sunday I realized the hills I used to have to go to granny gear to climb I now just ride up without thinking. So I guess it does get easier, it just happens kind of slow so we may not realize it.
