Two years ago, at age 62, I got back into biking after 30 years away. Bought a Trek Madone 5.2 SL and have put 4000 miles on it in the past two years. Did Ride Idaho 2 years, Stagecoach last year, Seattle-to-Portland this summer. Am thinking about riding RAGBRAI this coming summer and might try STP in 1 day next year. Am going to spend some time this winter in spin class and on a trainer.
