I recently completed my first IM, Florida (Nov 1). All of my training was done in heart rate 1 or 2. During the race, my heart rate stayed very low, never getting out of zone 2. Within three days of the race, my sore muscles were nearly recovered. I did not suffer any injuries during training or the race that I know of. I want to start running again but am unsure of how long I should rest. Does anyone have advice? Thanks.
