I just completed a 21 mile ride. I haven't done that since I was about 16yrs old. In 1 month I went from literally not being able to make it up the street (small hill) to getting over it and 20.5 miles on top of it! Yea I'm gloating! At this rate I'll be up to 100 mile ride next month, lol, not. Seriously after my first attempt at riding around the block I was so embarrassed and down with myself I never thought I get any further. I don't know what made me keep going on rides, this came out of the blue. I usually plan out and prepare to start excersising and never get past a week. After 18 miles I felt so good I seriously thought I could do 18 more, but the last 1.5 miles back to my house kicked my ass and I was glad to be home. I normally have a 6 mile ride I have been doing after work the last 2 weeks 4-5 days a week. I'm going to keep doing that and then do this ride again next weekend. I should have a real road bike by then, I ordered it last Wednesday. I have been riding a flat bar hybrid with 700x38 tires.
