Zero. The amount of running I have been able to do without (arguably) injuring myself more. I went running a few times in Portland, once on a treadmill and once out on the road. The treadmill was a disaster that ended in blisters after a mile and a half - of course just blisters on the foot with the problem which clearly indicated that I was compensating for the injured part of my foot by changing my stride. Not that I needed the blisters to tell me that, my foot hurt the whole time. The run on the road was better in that I didn't get blisters but it took a toll on my ankle, like the ankle was absorbing the energy from the strike rather than the pad of the foot. Not something you want at any rate.
I even tried a little soccer just for fun but that didn't work out so hot. I was half speed, couldn't pivot or cut, couldn't kick with my left foot and basically just sucked. I stood around in the goal for the second half of the game where I did marginally better, but ultimately was not very helpful even there.
About three weeks after the fact, my pinkie toe is still crooked and my foot still hurts. I guess I will go find my bike helmet for now.
