I've done a 100 mile UMCA event on a Baron. I got 1st in the Mens, 100 Mile, 50+, Recumbent category.
I think there were 2-3 of us.
Seriously, I'm considering doing some racing. I raced for 9 years in the '80s. Of course, I'm a little older, now.
The biggest problem that I have is that I don't want to travel 3 hours one way for 20-30 miles worth of racing. I'd rather stay home and ride with my peeps to breakfast.
Besides BP, Aikigreg and NoCom Racer from this thread race, also.
Lastly, some of the Chicago guys race regularly. They're not too shabby either considering one of them has a couple world records on a bent.
