I can't believe I'm going to tell you this. I just finished week 7 run 1. 3.2K in 30 minutes. I was so proud of myself however at the last two minutes I all of a sudden had to defecate so badly I thought I would die. I had driven to a public park but there was no place to hide and loads of people!!!! I ended up in my car with a plastic bag under me.. what a nightmare!!!
I Googled this problem and it seems to be a thing called runners diarrhea and happens to a lot of people.. so everyone please poop before you go out on your run!!! Lol.. public service announcement. .
