My lord. 150 miles on a singe-speed cruiser would be an accomplishment for ME, at 25 Y.O.
Heck, people were shocked when I rode the TdC century ride on a Giant TranSend with 700X32c tires and all. But lemme tell ya, a century on a 30 pound, 24 speed bike is not nearly as huge as what she is doing at 84. I am in awe!!!!
I might have a crush on this lady.
