or - you could just stop pedalling??.....Just Kidding!....I find higher cadence/lower gear works really well for me - especially when I"m climbing the mountain at night to get home. There are days I feel like I"m just spinning away and going nowhere really fast - until I get home and enter my avg time in my bike journal. Surprise - it always seems to stay right around the same avg and my legs aren't so tired I can't ride to work the next day - or hike the mountains on the weekends. There is a real sense of power in "mashing" the gears - but the price I pay when I do that is too high (re: too tired to ride the next day or hike or run that night).
