Wow, that's impressive! I can only hope to get to that point some day. I went a-searching for duathlon stuff as I am competing in my first trail duathlon in about an hour or two... I decided to wear my bike shorts and bike jersey. It's pretty short (1k trail run, 10k, mtn bike, 5k trail run) and I feel strong enough to do it for sure, but I'm worried my meager technical expertise for mountain biking will trip me up somewhere on the course. It's just a mile down the road, I'll be able to practice that loop whenever I want! This is a weekly event too just like the mini-tris we have here in town. I'm nervous but excited!
