At about what I figure might have been km 5 I was in dire straits looking for a spot to jump into the bushes and relieve myself. We got to the start way too late (40 seconds to start of the 10k) to be able to avail myself of the "services" which resulted in a HUGE need to poop and I was getting worried I was going to become the poop girl of Cancun. At this point I was SURE that I was running 6 min kms and was going to finish around an hour IF I managed to make it to the finish without shitting all over myself. Add in the ass on fire from the run in with chen-chen and I was a mess. I just wanted to get to the finish and go STRAIGHT to the portaloo. Apparently that was what I needed to PR as I finished in 55 minutes, for me, a PR of 5 minutes. I was so happy with that, especially with the dead legs from yesterday and ass on fire. Unfortunately, I must have had too much papaya at the finish buffet (check out the awesome fruit offered at the finish line) and I've been shitting my head off since. Seems fitting to add non-stop diarrhea to an ass already on fire from chen-chen. Still not sure if I'll be able to get on a bike seat today or not. UGH!
looking at my results today, it looks like my first 5K was just under 30 min, so 6-min kms and that means the last 5K was negative split, for 5-min kms. I am SUPER happy with that news.
