I've 'restricted', if that's the right term, my exercise to walking the past two days. Sunday I was out for two miles, and Monday 1.2. Unfortunately my bruised ribs aren't ready for lifting at the gym, and I was so wiped out by my ride Saturday I'm leery of riding any distance until I'm further along in my recovery.
As for recovery, it's been nine days since my accident, and I feel much better. As long as I don't do anything stupid, I should be OK in a couple of weeks. When I broke a rib in June 2008, I was riding long and hard in six weeks with little loss of conditioning. Of course, I was in much better condition then.
