I've ridden it many moons ago, and it's a route that's very doable outside the organized ride (I'd do it more often but it's always right around my son's bday). It's a great route, and don't let the 6500 ft of climbing fool you --Vail Pass in that direction at the end of the day is no picnic. Stunning scenery, good organizer, and a great route in general. It's definitely worth the trip -- if you can get out here a couple days beforehand to acclimate a little, that would be advisable. Elevation changes everything -- the
low point of the ride is almost 2x the elevation of Mt. Baldy. Insider tip: don't overlook Battle Mtn. It's a 2mi climb stuck in the middle of the screaming descent from Tennessee Pass. It kinda stings.
