Hmm.
Fastest speed recorded in a race, 100.6mph during the Wengen downhill in Switzerland by Johan Clarey (FRA). Previous record was set in 2005 by Stefan Thanei (ITA) at 98mph, and was broken four times during the weekend.
I'm not sure they have all speeds ever reached recorded, but I guess this is a pretty good achievement anyway. Would be fun to try...lol
