The tour was today but I've only been biking a month. Longest ride I've done is about 15 miles so far. Is it reasonable to think I can train up to 34 or 50 miles in 1 years time? I'm on a mountain bike btw, so it will definitely be harder. I'm at about 30-40 miles per week right now so I imagine the first thing to change will be slicks vs the knobbies on there now.
