60K and 200K Fat Pursuit

The Fat Pursuit is a 60k or 200k human-powered winter race on a network of groomed snowmobile trails in Island Park, Idaho. Groomed is relative. This is a backcountry event that will require some experience and winter survival skills. You will be challenged, humbled and rewarded in many different ways. The 200k distance course will not be marked and you will need to navigate by GPS or map and compass. The 60k will be well marked. If you can read a map you will have no problem following the route. You will need to be self-sufficient and carry all your own gear, food, and water, although there will be checkpoints and aid stations.

The race HQ and start/finish will be at Sawtelle Mountain Resort. 200k racers will tackle the highlight of the route early in the race: Two Top is in the first 30 miles, so you can catch the climb in daylight, in good conditions, when you're fresh.  

This event was created to help people gain experience and learn about backcountry winter travel. We feel everyone needs that chance and we do not require a resume of races to do the 60k or 200k distance, although past winter travel experience is strongly recommended.

Please understand that temperatures of 20 below are not uncommon. The snowfall average at 6300′, your low point, is over 200″ and over 300″ at your high point of 8300′. Snow is guaranteed!


You are being exposed to the same things the 200k participants are being faced with.

Sunday Celebration

At noon on Sunday, January 14 we will have a toast at the START/FINISH banner. This is an effort to celebrate all the riders, present or not, and a THANK YOU for being part of this event. Everybody is welcome, it is a celebration. I understand some might be on course and some may go home but I hope it encourages more to stick around and no matter where you are at – raise your water bottle or your glass and give a healthy shout out to the Fat Pursuit!

Ethics, Respect, and Safety

If you think of the words “ethics, respect and safety” in regards to your fellow competitor, other trail users, the land you are on, the event management and other establishments you come across we don’t feel we need many rules but here are a bunch anyway.

Any racer who fails to not meet any requirements and/or fails to comply with the following rules will be disqualified from the event. There will be no refund and you will not be accepted to come back.

  1. It is mandatory for all participants to be registered, signed off on the gear check, sign the waivers and attend the pre-race meeting before their chosen start to participate in this event.

  2. Support – No outside support is allowed. A racer may take help from another racer and race officials only while on the trail. A racer may use commercial services they come across only, as well as the Checkpoints. A racer may not take help from another snowmobile rider or trail user. This event takes on the self-supported style of racing.
    *Note – If this gets spoiled it will be removed from the future. Family members and/or friends that traveled with a participant may visit the checkpoints. This is to give the companion an opportunity to see the area, something to do, and add a little spectating. Do not give the associated participant anything and do not clog the Checkpoints. Maybe ask management if there is room first and DO NOT visit them on the trail. Thank you for respecting this opportunity to see a person you are rooting for.


  3. Bivvying / Sleeping – If you choose to bivy while in between checkpoints it is mandatory to remove yourself off the trail and set up. You must also face your safety light towards the trail to let others know you are out there and safe.

  4. Call of nature – When going to the bathroom please use etiquette. Go off the trail and keep it clean. Enough said.

  5. Evacuation – If we need to haul you off course for one reason or another it will cost you. It will cost you $250! Yep, come prepared! Hey 60km folks don’t take this “short” distance lightly and please come prepared – this applies to you too! 

  6. What you start with is what you finish with. You can not leave gear at Checkpoints along the way.

  7. Do not litter, don’t you dare.

  8. Don’t be a ….!

  9. Do not interfere with any other trail users.

  10. Do not ask or get a ride from a snowmobile and leave your bike in the woods unless it is a complete emergency that has you at risk. This will be hard to justify considering you have emergency equipment and camping supplies. Exhaustion or being tired of pushing your bike does not count as an emergency.

Mandatory Gear

(And the 200K Water Boil Test)

Carefully read the checklist!

200km - Sign-In AND Gear Check must be done on Thursday at race headquarters (Sawtelle Mountain Resort)

(Contact us for special arrangements if a early Friday morning needs to be accommodated)

Don’t make it difficult and arrive last minute thinking you are the only one. Make sure you show up prepared with all your gear! Don’t expect to be able to get last-minute gear in Island Park. Food, yes. Gear, not really. Please be somewhat organized for the gear check. Thank you


The 200km participants must stop and bring 8 ounces of water to a rolling boil at a undisclosed location before continuing on. 

  • You are only allowed to use the equipment and supplies you are carrying. 

  • You can use snow.

  • If at a Checkpoint you can not use the Checkpoint supplies.

  • You can receive aid from the Checkpoint before and after your water boil.

  • The water boil area will be monitored and flagged.

Checkpoints are also aid stations. There will be hot/cold water, sweet and salty snacks and GU products at each aid station. Additionally at each aid station there will be a highlight food of sorts ie grilled PB&J, potatoes, soup, pancakes...who knows but it will be hot and filling!

Drop bags are allowed for both distances. Details below.

CHECKPOINT 1, the "Lunch Stop" - Aprox 12 miles in, at a trail junction.


You will be able to get cold/hot water, grilled peanut butter and jelly, cup of soup, salty and sweet snacks and some GU energy products. 

CHECKPOINT 2, the "Snack Stop" - Aprox 25 miles in, in a parking lot.

There will be just enough here to kick you in the butt to the finish! So, for sure cokes and cookies and other mouth watering items. Along with cold/hot water and some GU energy products.

Both CPs are outside camps set up with tents and heaters. Mind you there is enough space inside the heated tents to dry some things and warm up but there is not a lot of space so be mindful and respectful of your fellow participants. First in, first out is the policy.

200k Details

CHECKPOINT 1, the "Lunch Stop" - 28 miles in at trail junction #40 on the snowmobile map. It is a 3.5 mile out and back off the main route to get to this CP.


You will be able to get cold/hot water, grilled peanut butter and jelly, cup of soup, salty and sweet snacks, coke, and some GU energy products. 

CHECKPOINT 2, the "Breakfast Stop" - 76 miles in at Harriman State Park.

You could potentially visit CP 2 twice but you will need to veer off the route at the end of the 12 mile loop you are routed to do in Harriman State Park. You go directly by it at the start of the loop.

At the CP there will be cold/hot water, bacon, Kodiak Cakes flapjacks w/ toppings, salty and sweet snacks, coke, and some GU energy products.

CHECKPOINT 3, the "Self-Serve Snack Stop" - 113 miles in at a parking lot as you cross a road.

Depending on when you arrive to CP 3 there may or may not be volunteers there. If not, you may walk inside and help yourself.

There will be just enough here to kick you in the butt to the finish! So, for sure cokes and cookies and other mouth watering items. Along with cold/hot water and some GU energy products.

All CPs are outside camps set up with tents and heaters. Mind you there is enough space inside the heated tents to dry some things and warm up but there is not a lot of space so be mindful and respectful of your fellow participants. First in first out is the policy.​

REMEMBER: Checkpoints are meant to be exactly that and act as an aid station/resupply. Race management did not organize these for you to sleep in but certainly rest if you need to.  

First come, first serve with the available space. The same goes for the first one in is the first one out when it gets too crowded.  You are carrying sleeping gear and can sleep outside, of course OFF trail. With that being said there is room to take time to dry.

Drop Bags

Both the 200k and the 60k will allow drop bags. They will be brought to CP 1 and CP 2 for both distances. 

Drop bags should include food only. No additional gear such as batteries, hand warmers, and clothing are permitted in the drop bag. You must start with all the equipment you need as well as finish with the equipment you start with. No dropping of equipment. Drop bags should be packed in a garbage bag with your name and number clearly written on them. When the checkpoint volunteers close the checkpoint and return to the Headquarters they will bring back whatever drop bags were remaining.

200K Only

(This does NOT apply to the 60km distance event.)

Tracking is mandatory. We work with for this service. 

The cost of this is on top of the registration cost and you will be getting an email from Trackleaders 1-2 weeks prior to the race for this service.

The cost is $20 if you use your own tracking device (SPOT or InReach) and $60 for a rented device. Reserved SPOT devices will be available for pick-up at racer registration.

If you have your own device Trackleaders will be asking participants for your ESN number and shared page link. The devices for rent are SPOT ‘Trace’ units (smaller and lighter) and operate on 4 AAA lithium batteries that you need to supply.

60k ​

No cut-off times. That said no bivying or long stops allowed, this is not the multi-day event. If you show me continual and constant movement I will let you keep on keepin' on! Sound good!?


CP 1 - Friday, 7 pm (12 hours)

CP 2 - Saturday, 7 pm (36 hours)

CP 3 - No cut off time but no bivying or sleeping when you leave this CP. You made it this far, now finish it up!​​​

**With respect to all the participants who are taking this Pursuit on and knowing the preparation that goes into it there might be flexibility with this. We want everyone to succeed but we also need everyone to be safe, including our volunteers. 

Also, understand the Race Director has the right to pull you if you are showing signs of being unsafe or are not prepared/equipped for the weather.

Trail Guarantee


Let's start by saying the routes of the event are part of a 500+mile trail system that gets groomed by the state. It's a multi million dollar program and there are big PistenBully groomers that go out each evening to groom trail. There is no set schedule as it depends on snow fall and trail usage on where they might go. Some trails get more regular trail grooming over others. The "trails" are the same as the Forest Service "roads" and the grooming is as wide as the road.

I've spent years building relationships and donate money (Thanks to Fat Pursuit!) to the Fremont County Parks and Rec that heads this program up. I put in my trail grooming requests for event weekend and have a finger on the pulse of mostly what is, has been, and will be groomed prior to the Fat Pursuit. 

This area gets a lot of snow and wind that can literally shut the trail down to a snail's pace within a handful of hours. Ask veterans, they know. As an event organization we do everything we can to keep the trail "open" and keep people moving. We have learned a lot over the years and have tried all sorts of techniques to deal with unrideable trails. Some were better than others. And then we found a tool that literally saved the event one year. This implement can blow a foot+ of snow off trail and get down to the existing firm service allowing a biker to start pedaling again. 

After that year so many people were thankful for that implement, gave it a name, and said WOW that thing is amazing. So, we crowd funded and bought our own.

Hence, I now give the "Trail Almost Guarantee," meaning "We will do everything we can within our power with our equipment and our incredible volunteers and their equipment to give everyone the best surface of trail possible."

*The person who wins the opportunity to register for the Iditarod Trail Invitational will have to be approved by me, JayP. I will be responsible for giving the Iditarod Trail Invitational organizers the OK on your ability and that you are capable of competing on that trail. As I have a full understanding and great respect of what the Iditarod Trail Invitational has to offer I will only give my honest opinion to both you and the organizers. In short, just don’t do anything that will put you or anybody else at risk. Thanks for understanding.

The Fat Pursuit 200k is a qualifier for the Iditarod Trail Invitational.
