I'm doing great on my Sun recumbent after 8 weeks! I will be up to 500 miles tomorrow. I rode the local metric half-century last weekend and that wasn't enough so I continued riding afterwards and did 45 miles! I'm planning on doing a metric century in 3 more weeks. The bike is still slow in comparison to a standard bike; I'm guessing I could go at least 3-4 miles per hour faster for the same effort, but I am riding again! Yay! I've kind of decided that if I can ride a metric century with at least 3000 feet of climbing, that I will spring for a better recumbent. I haven't done much climbing yet on the Sun, though I did do about 750 vertical feet of a 7.8% grade a couple of days ago. Whew, that was hard on a heavy recumbent! I had to rest all day yesterday to recover, and I'm thinking of lowering my gearing now. I can't wait for a lighter bike!
