I'm training for my first Duathlon in about 8 weeks (a run, bike, then another run). I have raced both road and mountain bikes a few times before, and have run many road, trail and mountain races- but never raced both sports together. When doing "bricks" in training I've changed from my running shorts into cycling shorts and vice versa when mixing it up, as I find the bike shorts are really uncomfortable to run in with that pad between your legs. I could ride in running shorts even without the padding, but they billow out and catch the wind like crazy, not to mention they'd probebly chafe. Are there any shorts out there that are good for duathlons?
