I am training do a 13 mile fundraiser in mid-August (I am swimming across Lake St Clair in honor of my son, who was recently diagnosed with cystic fibrosis). However, last Saturday I cracked a rib, and am up in the air about continuing to train. I have backed off but still have done 11 miles since it happened. My pain doesn't seem as severe as I would expect, and am waiting another week to go back to the doctor. Any advice?
