A horrible race. It never happened before, but I had to poop during a race. The reason is that I used this opportunity to eat a lot the night before the race. Delang's wisdom: don't big dinner before the race. So no salad for the lunch, should have had PASTA for lunch and light carb-rich dinner before the race.
Pace dropped uphill and did not enjoy the uphill run. Looks like I need to run more hills.
