40.8 mph - A New Record!
For me anyway. And yes, it was downhill.

I have tried several times to break 40 without success.

I am getting much stronger but I really cannot push the gearing I have on the bike right now (if ever). So I am swapping out the current cassette that is an 11-23 for a 13-26. Should make it easier uphill as well. And hills we have in abundance in Oregon.

Although to put my strength (or lack of it) in perspective, the Tour d'France guys average around 27 mph, I'm lucky to crack 16.
