- Length: 9.5 miles
- Elevation gain/loss: 1,400/1,900
Driving Directions to the Start of Leg 11
- 53 miles, 90 minutes from the start of Leg 10 at Jefferson Lake Road.
- From the Beaver Ponds Trailhead, head southish on Jefferson Lake Road (County-37) for about 3 miles.
- Turn left on County-54, Michigan Lake Road. (Don't turn right here - see below*.)
- After 2.0 miles, turn right on US-285 and go 15.9 miles.
- Turn right on CO-9 and go about 23 miles to Breckenridge. Continue on CO-9.
- About 3 or 4 miles north of Breckenridge, turn right on Tiger Road. (If you get to the Gold Hill Trailhead on the left, you've gone just a little too far. Don't turn on Tiger Run Road. That's different.)
- Go 5.7 miles on Tiger Road.
- Just before a one-lane bridge, turn left on FS-354a. (If you get to "Good Times" dogsled camp, you've gone 0.25 miles too far.)
- Drive up FS-345a for 0.7 miles until the Colorado Trail crosses. There is a spot for one car to park on the right. If it's full, head up the road for another ~0.1 miles and find another pullout.
- *Absolutely do not follow Google Maps unless you are ready for some pretty serious offroad driving. It tells you to take Michigan Creek Road, which is rated a 3 on TrailDamage.com and basically means that you need a a Jeep wrangler or better.
Running Directions
- 0.0 – From the dirt road, start running northwest on the Colorado Trail singletrack.
- 2.9 – After cresting the big hill, continue straight on the Colorado Trail as another trail goes right.
- ~3.3 – At an unsigned intersection, take the left fork (downhill) as another trail goes to the right.
- ~6.0 – Emerge from the trees and bound down several broad switchbacks.
- 6.2 – Come to a three-way junction. Make a hard left to stay on the Colorado Trail. There is a single small signpost with a little "U-Turn" arrow.
- 8.8 – After coming down some switchbacks, turn left on doubletrack under some high-voltage power lines. Follow this rocky trail around a gate and over two bridges.
- 9.5 – Arrive at the Dredge Boat Trailhead. (There is a pond here.) Finish!!
Driving Directions to the End of the Race
- 3.9 miles, 15 mins from the start of Leg 11.
