When younger (getting to be a depressingly long time ago) there used to be informal racing on a paved access road along Haulover Beach in the northern Miami area. Really what it was was sprinting. We'd measure our sprints by the number of light posts. Use 1 post to post distance to wind up and sprint for 3 more as I recall. This was during the Bike Boom days and there were numbers of roadies out there like you'd never see anymore today. Since we usually put a couple of dollars or maybe a pair of gloves on the outcome it was pretty serious.

I used to be pretty quick even on a heavy bike but no computers so no numbers. Joe, I'd bet with your 40mph or so on fresh legs you could have made a few bucks on that beach road back in 1979 or 80.

Because of a motorcycle accident I can't really stand up on the pedals effectively so sprinting is a fond memory but a dog pushed me up to about 30mph a few days ago.
