Don't Muddle The Puddle - When riding in muddy conditions be careful at puddles. It may seem fun to blast through. But it's never a good idea because you can't be sure what's at the bottom. If there's a hole there, you'll end up doing a sweet Superman imitation and sail over the bars when your front wheel gets stopped cold. This will entertain your ride partners immensely but it can be quite painful and could wreck the fork and frame if you're really unlucky. Our recommendation? Slow way down and try to gauge how deep it is. If you decide it's safe to ride through the middle, get your weight back and off the front wheel. Or, if it looks deep, try skirting the edge of the puddle so you know you're passing over solid ground. Or, if the puddle is pond like, get off and walk around. The goal is to pass safely and to not widen or damage the trail, too.
