I have... close to a dozen times.
I think that last year the registration closed early April. It was a lonely, wet slog last year. I was tempted to ride to my place in Dillon as I turned to ascend Swan Mtn.
It was nothing like the '98 ride ...hottest one on record at near 100 degrees.
It's an awesome route.
The BBQ in Avon is good.
The rest is a mixed bag.
There are lots of riders ...3000 plus all the poachers.
The weather can be all over the board, as you well know being from CO.
The descent from Vail Pass is always my biggest concern. It's a steep route with lots of tired souls. Then the roll into Avon after that descent will find those same tired souls hanging onto stranger's wheels ...sometime a paceline of more than 30.
It's a great ride to do with friends.
