I recently entered into a competition that involved racing (on foot) across a large muddy bog. It wasn't very deep, but it was very sloppy and sticky! It was at a village fete / fun day that was happening locally. I think I surprised a few people by going for it without changing my jeans, socks or shoes! It was hilarious as I splashed at full speed into the mud and squelched as fast as I could across it. I didn't win, mainly because I had to stop to retrieve one of my shoes! What a silly, but very fun game this was!
