My Chemo has had me off my bike since March. Had my hamstring removed July 9 and I did a few 5 mile rides just to prove that I could do it, but when the chemo resumed, I wimped out. I could ride, and have been encouraged by several here to keep riding through it, but it has just sucked everything out of me. End of treatment is March 10th. Will hopefully start riding again by April 1. I miss it.
