Course and logistics
Both distances start and finish at Valley Spur Lodge. The 50K is an out-and-back that follows a section of the North Country Trail to the Rock River Canyon Wilderness and back. The 50K route includes about 26 miles of single track and roughly 5 miles of dirt forest road, with approximately 4390 feet of cumulative ascent and descent over about 31 miles. The 27K follows the same corridor to the AuTrain aid station and returns, and is described as entirely single track.
There are six aid stations located about 4 to 5.4 miles apart at approximately 4, 8.4, 12.8, 18.2, 22.6, and 27 miles. Runners are required to carry a 20 oz water bottle or functional hydration system for refills. Parking is available at Valley Spur; a drop-bag tent will be located near the start/finish area. The 50K has an 8.5 hour time limit and aid stations have scheduled closing times. Visit the organization's website for the most recent information.
