I did a 55 min 5k. I realised at the half way point that "funny feeling" I had was food poisoning. Sadly too it was an "up and back" run so i had to keep going. I was thankful for fats on the circuit that day as a couple stopped to help, and one had baby wipes which I took a few of to run into the bush. It wasn't my finest hour, and I'm def against unhygienic practices, but you gotta do what you gotta do. I still beat them coming back.
