Thanks for the good wishes. I'll write up a report but here's the gist. I was on 3:10 pace right up until kilometre 39. Maybe even 39.5. Then the cramps hit big time. I had to walk. I tried to run and I did. The sun was hitting me (Toronto, plant some freaking trees!) and I was just a mental mess. Thanks to Peter, a former co-worker who ran that half, who came up and helped me get my bearings straight in the last 500 metres. It was a painful last two kilometres and I managed to run in bits but I was a stumbling mess. The marathon is humbling -- I know that very well.
Next time, indeed. Race report in a few days I think.
Chip time: 3:19:39
