Ute 100 - Race Information & Rules



Weekend Schedule


Packet pick-up  

There is no packet pick-up on race day!!

Packet Pick-up and Gear Check

To get your  race bib, you must present a valid government I.D. and show the volunteer the required gear

To make this fast and easy, put only the required gear in a large clear plastic bag, so that everything is visible

If you don't have your gear or are missing an item, the volunteer will ask you to go get the required items and return to gear check. Once the volunteer sees you have everything, we'll tag your pack and you can obtain your bib

You can only get a bib in person with a VALID government I.D.  You cannot get a bib/shirt for a friend or get a bib the  morning of the race!!!

Runners will get a crew pass (one per runner) which will allow ONE vehicle access to crew accessible aid stations and the starting area. The crew access pass must be visible in the vehicle to avoid being ticketed, towed, or the runner DQ'd.

Runners will get one safety runner bib which they can use from mile 51. (Miner's Rd AS #5)

If you have a drop bag, bring to packet pick-up on Friday 8/7.

We will review any last minute changes, safety, aid stations, safety runners and general Q&A.  If you show up race morning and did not pick up your bib and attend the pre-race meeting on Friday, you will not be allowed to participate!  We are serious about this!


  • Check-in at the start. This is a mandatory re-check. Every runner will be scanned as part of the check in process. If you bypass it, and we find you somewhere on the course, then we will have you pulled for a DNF.  Make sure a check-in volunteer, puts a check by your bib/name and your are scanned into LiveTrail.

  • Race start


There is a 40:00 hour total time limit with individual aid station cutoffs. The cutoffs are tighter at first, then loosen up as you get closer to the finish. It is YOUR responsibility to know these time limits. We DO NOT recommend basing your distance solely on GPS devices. GPS devices can vary in accuracy. If you are riding cutoffs then be prepared to not make a cutoff. Please do not get angry with a volunteer if you do not make a cutoff time and are asked to stop. You must turn in your bib if you do not  make a cuttoff. These are STRICT cutoffs and are for leaving the aid station, not getting to the aid station. AGAIN all cutoff times are for you LEAVING the aid station.

Dropping Out

If you drop at an aid station where there is no crew access, you will have to wait until the aid station closes to catch a ride back to the finish area. If you drop out, you must notify the AS Captain. This will help us account for all runners and ensure no runner is left out on the course.


Please note that there will be road crossings that may not have crossing marshals. This could be during the daylight or during the night. YOU ARE RESPONSIBLE FOR ENSURING YOUR SAFETY WHEN CROSSING A ROAD.

If you or another runner has a LIFE THREATING emergency please dial 911. Sometimes the closest aid station is behind you.


The weather is a dominant factor for this run and can be as formidable as the terrain, remoteness, or high altitude. The average temperatures range between 45 to 85 degrees Fahrenheit. Expect cool mornings, and cold nights. Daytime temperatures can be hot, 90+, especially on the Jimmy Keen, and Pinhook Valley loops.

The typical daily weather cycle is as follows:  The morning will start out cool with blue skies. As the day warms up, thunderheads will build quickly. Around noon, intense electrical thunderstorms may commence, continuing until late afternoon or evening, at which time the thunderstorms abate until the next morning. The LaSal mountains are typical of the nearby Colorado mountain ranges. The Colorado Mountain Club advises climbers in Colorado's mountains to be off the peaks by noon.

Depending on your position on the course, you must use extreme caution. During inclement weather you may have to run above your comfortable pace to get through a section before a storm hits, or you may have to stop and seek shelter and wait it out.  Remember that the time limit is 40 hours. The cutoffs allow for slower paces during the last 20 miles of the race.  These slower paces are a buffer that may be used by the Race Director to add some time to some cutoffs if he sees fit. The long time limit is not only in recognition of the difficult terrain, but also allows runners to wait out thunderstorms or other life-threatening weather during the race.  If you are pinned down, chances are that other runners are too. Your position in the field will probably not change. Use the time wisely - eat, drink, stay warm, and rest. You will be able to run faster when the storm has passed.

At the discretion of the Race Director, Aid Station Captains can hold runners if weather conditions are considered too dangerous to continue. Several runners in other races around the country have been struck by lightening. DO NOT BE THAT PERSON! We will continually communicate warnings, cautions, updates, and suggestions regarding the exposure you will face when attempting this run.

In the event of severely inclement weather, the race may be cancelled, or an alternate rain route, using mainly USFS roads may be required.  We will do our best to have the original race route, however, no refunds or deferments will be given for any reason. Thank you for understanding.
