Yesterday I got out at 4:30pm for another "training" ride on the Handsome Devil. ~8 miles in ~1 hour. Included some gravel simulation -- ice covered with thin layers of slush or crunchy snow. I'm having problems with my left foot & ankle. Last week I was sure it was planar fasciitis, but last night it felt like achilles tendonitis. How do I pile on the base miles but rest that?
