5 years ago I was 25# heavier and gasping for air on a 2 mile bike ride. Last weekend I rode a metric century supported ride at the Fallon No-Hills Hundred. Including the ride to and from the start line I logged 75 miles in 5 hours. Yes, I hurt the day after. Yes, I will do it again, only faster. You, too, are not too old to get thinner and faster.
