Did my first actual mud race yesterday, the 10-mile Philly Tough Mudder. After much deliberation, I wore my G7900-1 and couldn't have been happier with its performance. It was never in the way or caught on anything and had no issues. It was my first mudder, I wasn't concerned about my race time or anything, but it was nice to have it with me to check the time of day a few times. We did it in 4 hours.
This was after I banged it off a bit. There were times when I looked down and it was just one big mud ball! I took it in the shower when I got home and rinsed it and cleaned it with an old toothbrush and it's good as new.
