Race Course Details

Race Division – Will do approximately 5000ft of elevation gain/loss and over 10 miles long over a three loop race course, see map(1,602km/16km)

Recreation Division – Will do approximately 3500 ft of elevation gain/loss, over 6.5 miles. First two loops of the Race Division’s course (going right to left when looking at map).

Both divisions should anticipate a boot pack section on the course (snow/weather condition dependent). It is mandatory for you to have your skis on your pack. We may have a hand line in place for this section. You will want a free hand to grab the rope/rocks as it will be “sporty” …and fun!…so NO hand carrying your skis!

Race Course Closed

At 2:00PM…you will be told by course marshals to go down from where ever you are on course. Racers should be headed out for their last lap by 1 PM and could get stopped and escorted down if not finished by 2 PM

Transportation To/From Race Venue

If you are snowmobiling to the race, please take the standard road up to towards the Lake Irwin Campground (FS Road 826 AKA Irwin Lake Road) up to Irwin Lodge. DO NOT GO THROUGH THE IRWIN TOWNSITE. Additionally, do not stress the organization or fellow racers by joy riding before the race and getting stuck. Be on time, and sled neck around AFTER the race. Its about a 25 minute ride up to the Start line from the Kebler parking lot/trailhead.

****If you are getting towed behind a snowmobile, have plenty of warm clothes…with no exposed skin on your face.

Weather Links

Base Area Facilities

This is truly a backcountry ski race. There is no big base ski lodge or cafeteria for you to buy food. We will have several small shelters and two porta-potties for you to use. Be prepared with lots of EXTRA warm clothes, especially if the weather turns cold/snowy.


We will have beverages at the Start/Finish and at the bottom of all three skin transitions. Bring some pre/post race food and (hot/cold) as well.

Ski Fast!
