I'm working my way towards the Silverman 140.3 race in November. Reading about the race, it looks like there will be some climbing on the bike course. Therefore, I want to improve my climbing abilities but am not sure how. I know the quick answer will be "get on the bike and climb." That's all good, I live in Colorado, so I have no shortage of climbs to ride up. My questions is more around technique. Should I be trying to keep my heart rate in check on the climbs, even if it means using my granny gear?
