Course Description, Map and Race Profile

The inaugural Drift 100 will begin on March 13, 2020. The course is approximately 101 miles (because why stop at 100, #amiright?), with around 7,300 feet of elevation gain/loss. This is a self-sufficient race. No drop bags, no pacers, no cell service. Check points are separated by upwards of 35 miles of varied conditions and temperatures. Much of the course is along the Continental Divide, as Drifters will be both navigating back and forth over the Divide itself and traversing it, you will reach elevations just shy of 10,000 feet. 100-mile Drifters unable to finish the race will be required to pay a $200 drop-out fee to Tip Top Search and Rescueno exceptions. This recreation event is authorized under a Special Use Permit with the Bridger-Teton National Forest and the Shoshone National Forest.

This course will start and end in Kendall Valley along the Green River, 25 miles from Pinedale, Wyoming. Racers will head north toward Dubois and head back, forming a figure-8. Less than 10% of the race will be traveled twice. Race time cutoff is 48 hours. The course is approximately 101 miles with 7,300 feet of elevation gain/loss and topping out at around 9,800 feet.


Racers must qualify for The Drift 100, however, there is no specific qualifying race. You must be able to prove you can safely and independently complete the course. Previous completion of a similar winter ultra such as Arrowhead, White Mountains, ITI, Susitna, Fat Pursuit, etc. will allow you access to the 100. Not sure about your qualifications? Reach out to Race Directors Keri or Darren with any concerns before registering. On the registration form, please list previous race, expedition and/or winter travel experience and any other experience you feel is relevant. Racer acceptance for The Drift 100 is ultimately decided by Race Directors. Registration will open October 1, 2019 at midnight. If you register and the Race Directors deny your acceptance, you will receive a full refund, or you may switch distances (sign up for the 13- or 28-mile course) as space allows or roll your registration into 2021’s races.

Aid Stations

There will be three manned, heated aid stations along this course at approximately mile(s) 25, 55 and 83. Aid stations will have water, hot drinks, soup, something sweet and something salty. Exact locations and cut-off times will be revealed at a later date.

Course Map and Profile

This is the initial map and profile release. This is currently tentative and subject to slight modification. Stay tuned for any updates to this course, as much of it will be weather dependent. Locations for aid stations are not listed on this iteration, but will be on the final map.

Sleeping on the Course

Keep in mind that this is a race, not a tour. Space is limited and not guaranteed in the aid stations. Should you choose to sleep on the trail, you must go at least 10 feet off the trail, but keep your blinking light visible to volunteers, other racers and trail sweeps.


The Drift 100 has partnered with Trackleaders. All 100-mile Drifters will be required to carry a tracking device. Racers are encouraged to use their own devices (either a Spot or an InReach). If you do not have one, you may rent one for $35. This is REQUIRED for all 100-milers, even those who choose to travel together. Although this does add an element of safety to the race, it by no means allows for unprepared racing.


Although every attempt is made to make this race as safe as possible, Drifters are reminded that you will be traveling through 100 miles of extremely remote wilderness in variable, often formidable, conditions at altitude in the winter. You are ultimately responsible for your safety. For 2020, the 100-mile race is capped at 50 competitors, so it is likely that you may not encounter anyone between checkpoints, or for several hours at a time. There will be limited snow machine support and course sweeps. Do not underestimate the difficulties of this race.


In the event a racer is unable to finish the race or if they miss an aid station cutoff, they will be taken off the course via snow machine. It may not be possible to evacuate from the course immediately. Be prepared to wait. Racers may initially be taken to a heated aid station for a time before a full evacuation can be completed, based on volunteer availability and race flow. All racers evacuated from the 100-mile course are REQUIRED to donate $200 to Tip Top Search and Rescue. Exceptions: if you turn around south of Strawberry Safety Shelter, you may return to the start/finish on your own, or if you arrive to the Moose Manor checkpoint on your own and choose not to continue, you may have someone pick you up via car. Racers will not be permitted to leave the course on non-race snow machines.

We know it can be a bummer to quit a race. We know the mood. We know you’re tired, you’re pissed, you’re disappointed, you’re hungry, you may be hurting, you’re probably freezing, and you’re just plain defeated. But, be grateful for assistance off the course. Pay your drop-out fee and be kind to your evacuator. Be patient if you have to wait. Remember that these folks are only there because they have volunteered to help you (even in the middle of the night), not to put up with your crap. So, if you need to get a ride out, swallow your damn pride, pay the fee, and be a nice human. K, thanks.


Racers are expected to start and finish with all gear they will need for the course. Racers may pick up snacks and drop trash at aid stations. There is no caching or outside support allowed. This includes dropping gear you are not using, towing or receiving food, water or a ride from anyone not affiliated with the race. Doing so will result in disqualification. Racers can and should help each other. Buddy system is always encouraged.


March in Pinedale is still very much winter. The average high is 38*F and the average low is 7*F. March is the windiest month (and, hey, that’s really saying something) with an average wind speed of 8 mph (but it’s totally going to be windier than that).  However, temperatures in Sublette County in March have been as cold as -39*F. Read it again. For real. (yes, it says negative.thirty.nine.degrees.fahrenheit). Keep in mind that much of your time will be spent between 9- and 10,000 feet. You will have 12 hours of darkness. Wyoming doesn’t f**k around: frostbite, hypothermia, dehydration, sun- and windburn are all very real and potentially deadly dangers here. Be prepared. Be overly prepared. Should you show up for the race under-prepared, it is at the discretion of a Race Director to determine whether you can safely race, and you may be denied entry, without a refund on your registration fees. So get your shit together and be safe.
