Its scheduled for June 14,2008. Here's a description:
The start will be at Loveland Ski Area with an elevation of 10,600'.
The race begins with a 5 mile sprint across a dirt trail to Bakerville 9,780'. It is here that riders will mount their mountain bikes. The mountain bike leg will take riders from Bakerville into the historic mining town of Silver Plume along the frontage road.
From Silver Plume, riders will then climb uphill on dirt to Pavilion Point, down to Guanella Pass Rd and over to the abandoned mining town of Silver Dale.
From Silver Dale riders will enjoy another new section of rolling trail that will drop them into
Georgetown by the water tank. From here it is mostly dirt roads through G-town (Taos St - 6th St - Main St, Saxon Mtn Rd) At the first switchback of Saxon Mtn Rd, riders will stay left (looks like your going down a driveway) to link up with the Silver Creek Trail.
Bikers will finish their leg in the town of Lawson(8,000') where the HIGH WATER whitewater section will begin. This section is ONLY FOR EXPERT PADDLERS (KAYAK/CANOES/RAFTERS with solid rolls and self rescue). This leg is 12 miles of class III/IV whitewater excitement. The gradient is almost 90'/mile!!!
Paddlers will be going through the towns of Lawson, Dumont and Idaho Springs. This will take the racers to the finish line located across the highway from Kermit's Restaurant and Bar. (7,200') The total descent from start to finish is an incredible 3,400 feet. Awards, music
and beer will be held at Kermitt's Bar.
