This was hilarious and very relatable. But a full bladder is nothing compared to the worse problem.

Running gets the bowels moving like nothing else and every runner has a super embarrassing poop story about their running career. The urge for me was once so excruciating I had to walk, and I was about 2 miles away from my house with no bathrooms in sight. I made it, and then realized I forgot my key. At that point I couldn’t hold it anymore — I had to go in the backyard.
