I was riding with a few friends yesterday and one of them is a proper roadie, the kind that does 60 milers easily and breezes up the biggest hills. he's been riding for 4 years, anyway he explained that going up a hill in a high gear will burn you out much quicker. He said best to spin up the hills at a comfortable cadence, which I find works.
So yesterday's ride was a blast. 6 of us did about 35 miles (annoyingly s trava died 8 miles from the end so it missed my last bit), my furthest so far. Felt good afterwards and for the last 15 miles I was blasting past all but one of our group up the hills. Loved it. Had a slow avg speed though which was a shame. One of the hills we tackled was a proper killer! 2 of the chaps had to get off and walk.
