After I tried biking the half-Ironman distance last year on a rented road bike with no fenders, I was probably my bike-messiest. The route I was supposed to have taken... either I got lost or it wasn't as advertised (around the bottom of Lake Sammamish State Park), not sure which. But I was biking across a mud field... on a road bike... yeah. By the time I got to the REI in Redmond everyone gave me the respectful distance of immense street cred, by which I mean I had no idea until hours later that I had a giant rooster tail of mud up my ENTIRE back and walked around Redmond Town Center like that for an hour and change. Hahaha, whoops.
