The short race 350 miles starts at Kink and finishes in the interior village of McGrath on the Kuskokwim River. After leaving Knik the race route is completely off the road system. The trail leaves Knik and traverses frozen swamps and lakes to the Susitna River.

Turning right onto the river we follow the Susitna to it's confluence with the Yentna River. The trail continues up the Yentna River past the confluence with the Skwentna River before turning left off the river and arriving at the second checkpoint, Skwentna Roadhouse approximately ninety miles from the start. 

The trail leaves Skwentna and heads into the foot hills of the Alaska Range. Beyond Finger Lake the true wilderness begins as racers continue climbing higher into the Alaska Range over what some feel is the most challenging section of the trail. After thirty five miles of steep climbs and drops you arrive at Rainy Pass Lodge the checkpoint on Puntilla Lake. 

The next section is from Puntilla over Rainy Pass to Rohn. The trail leaves Rohn, crosses the South Fork of the Kuskokwim River and up into the Farewell Hills. Forty two miles from Bison Camp you arrive in the Athabascan village of Nikolai, competitors then leave Nikolai on the final stretch to the finish of the three hundred fifty mile race to McGrath. This section of trail crosses miles of frozen swamps travels down the Kuskokwim River then goes overland the last few miles into McGrath to the finish line.
