I live near the mountains so a fast time for me would be 31 MPH average over an 8 mile descent.
On a short 1 mile hill, Gina and I hit 56 MPH on the tandem, without pedaling!
We didn't want to go that fast but the tandem took us there. Rock solid but too fast so we avoid that course. Bike rock solid but glasses and helmet shaking like a muthah!
On a single bike, 42 MPH. I did some long mountain rides that had long descents on mountain roads. Can't help but go fast on a 30 mile descent!
