First..my situation. 53 years old. Former runner but ruptered my left quadricep in 98. Leg works okay now but won't let me run. Weight is 202lbs on a 5'8" frame. Retired from the Army in 97 and it's time to get back in shape. Recently bought a Trek 2.3 and started to ride again for the first time in 30 years. I am in a cycle camp and am learning group riding skills, basic bike maintenance and going on 2X weekly group rides of 12 - 16 miles (flat, rolling hills and just plain hills-if you get my drift) I am doing great, loving the bike and am looking toward longer rides, touring and racing eventually. Now my question: My trainer is encouraging me to ride a half century that is coming up in 3 weeks. She has told me that based on the rides we have done so far, I can do it. I have almost no time to train other than just slip in 3 long slow rides each Sunday and then go for the Half Century. My plan is to do 20 miles; 30 miles and 40 miles on consecutive Sundays then the next Saturday (June14th) do the ride.
Am I crazy? Anyone have a suggestion for taking an out of shape 53 yr old and training to ride 50 miles in 21 days?
