I ran the Mississauga Marathon on Sunday and finished in 3:51:28. The ankle was still a bit sore and then I rolled it at the 18k mark (oops) which definitely caused some pain, but it did subside, but I was left with a swollen ankle (swelling's down now).
All in all, I was definitely happy with the race. There was wind and rain, but I didn't mind. I ran a marathon. I even knocked a few minutes off my half marathon time.
