Maybe I'm getting old. I'm getting dropped more and more by youngsters on MTBs. I can hear the hum of their fat knobbies approach me from behind, and I ease up on my pace to let them pass. But I catch up to them at stop signs and lights, and it occurs to me it's exactly the same thing in cars. All those muscle cars burn tons of fuel to accelerate past me, only to wait at the next light while I gently coast towards them to start the cycle all over again.

I keep a constant cadence from beginning to end and could care less about those that huff and puff.
