5th Metatarsal Avulsion Fracture

Three weeks ago I was out for a quick "shake out" run before making the long drive to Coeur d' Alene to compete in my 4th Ironman. Car was packed, bike was loaded and ready to go. During a very routine run I stepped on a rock, rolled my left foot and broke my 5th metatarsal. Just like that, 8 months of hard work down the drain. I was devastated...still am. Confirmed at the ER and again at the Ortho as an Avulsion fracture (not Jones). The fracture is "minimally displaced" and another foot surgeon called it "VERY minimally displaced". I've been in a boot/cast and using crutches for three weeks now. Swelling subsided about a week ago. Foot looks better. Pain is decreasing ever so slowly. I use crutches when going long distances (to the parking lot, at the store, etc). The Ortho has taken the ultra-conservative approach with me (I feel). Telling me 8-10 weeks in the boot/cast, start swimming around 3-4 weeks, stationary bike around 6 weeks, no road bike until 8 weeks and then a full 12 weeks to run again. Last week I swam for the first time 1,500 yards, pull buoy the whole time, no pushing off with bad foot, was super careful. Immediately after swimming there was pain near the fracture and that pain kind of worsened as the day went on. Anyway, I thought I'd post all of this in case there are others out there who have had this injury and can offer their experience or advice.
