I was running my first mountain bike duathlon this past Saturday: 5k trail run - 10 miles mountain bike - 5k trail run.
After about 2 miles on the bike my pedal got caught on something after going over a log and broke. Since I had no way to repair I continued until the end of the first 5m loop. It was a really fun race and I didn't want to abandon, I was so mad! So I took off for another 5 mile loop with a broken pedal and then completed my 5k barefoot. My time was really bad: 2h32, with almost 40 min to complete the last 5k, but I *really* enjoyed it.
The best of all: I got an award for that! For continuing with a broken bike...and for being the only crazy person to run barefoot. The race was named the "Odd Man 1.3.5 Racing - Uncommon Racing for the Uncommon Racer..." So I fit right in!
I just wish I had been wearing shoes more substantial shoes than my water shoes since the 'pedal' kept rolling under the arch of my foot and my arch ended up a little bruised from that pressure.
