After 8 days of no running I finally decided to give it a go. Looking back it was a really dumb decision (really?). For some reason I thought doing a 12 x 400 track workout at 5k pace in the pouring rain was a good way to ease back into running.
Two more decisions hopefully limited the damage - 1) I dropped back and decided to run with the cool kids in group 2 and 2) I quit after running 8 repeats. Unfortunately it was probably 8 too many. Too many left turns which didn't help my left side pain.
A major setback indeed. I can't even walk without pain and I can barely make it up stairs. I'll be changing my blog name to HAV2BIKE shortly.
