I'm doing it. Racing my first bike race. Well...sort of. A duathlon. It is: 5K run 30K bike 5K run. I don't swim...well. Drowning would be bad, so would getting rescued. But I run well. And love to bike. May 7th here in Denver. The Barkin' Dog Duathlon( Barkin' Dog Duathlon: Mile High Duathlon Series #3 ) My first such adventure. Have ran several races, a few 1/2 marathons and a full. So the running...I do anyhow just for health. Biking, that gets hard in winter. I'm in shape, good shape, but that's RUNNING shape. I am running and have been running 25 miles a week. How long will it take the body to adapt to the bike? How long for my very sensitive bumm to harden a bit? I have like 7 weeks until race day. My thinking is 1 day a week biking, 1 day a week running/biking, 1 day a week biking/running, 2 days running, 2 days resting. (that's 7 I think) Practice my transitions once a week, too. Clothes? Should I get tri bike pants? No way I can run in padded bike shorts, No way do I want to ride unprotected? A bike race...I am excited. Anyone do a multi sport race? Fun?
