Zion Trail Half Course Description

The Half Marathon course heads east on a fast downhill dirt road to Grafton Mesa Aid (mile 1.3). You may stop if you like, but you can also skip this stop and continue on the fast downhill run toward Wire Mesa.

Once you arrive at the Wire Mesa Aid Station (mile 3.2), you will begin run by covering this incredible section of trail at sunset! Wire Mesa has great up close views of Zion and wonderful, very runnable trail conditions. During golden hour, its magical. There is not a lot of elevation variation, so take advantage of it. You will return to the Wire Mesa Aid Station (mile 10.4) before beginning your uphill trek back up the same dirt road toward Grafton Mesa Aid Station (mile 12.3) and the finish line.

If you are a runner who likes to get their money’s worth, be sure to pack a head lamp, although you may not need it because in 2025 race day should be a full moon.

If any item is of critical importance to your ability to finish, please consider putting it in your drop bag. 

While we do our best to help each runner finish the race, food selection and nutrient needs vary between runners. If you rely on a specific food or hydration routine, please use the drop bags to pack what you need along the course. 

Drop Bags (Ultras only)
Drop Bag Rules

For any ultra marathon distance you may use drop bags. You can leave a drop bag at designated aid stations. Please observe the following rules: 

  • All bags must be labeled with name, bib # (in large print), aid station, and race distance. Optional, but a good idea if your label comes off, is a card inside with the same information and contact information. Please label your bags the day before the race on your own or at check in.
  • 100 mile & 100K drop bags must be left in the designated drop off location (near the start line) by 8pm the night before the race.
  • No valuables or fragile items in your drop bags. We are not responsible for any lost/stolen items.
  • Watch the weather forecast. If there is any chance of rain, place your items in zip lock bags inside of your drop bag.
  • Minimum size: Gallon size freezer zip lock. No grocery store plastic bags or garbage bags.
  • Maximum size: Shoe box size for single pass and daytime aid stations. Small duffle or small carry on for multiple pass aid stations.

Half Marathon runners should not use drop bags. Please speak with a race official if this will create a problem for you.

Drop Bag Return
  • Generally, all bags come back about 90 minutes after the aid station fully closes (all distances that pass through it). 
  • There will be a "Return to Finish Line" area at all aid stations that allow drop bags. This is an area where you can place your drop bag after you no longer need it from that particular location and we will try to get it back early if possible.
  • You must place the bag in this area. Crew or volunteers are not allowed to sort through them in order to reduce the risk of a drop bag inadvertently being returned to the start line.
  • If you do not want to stick around, we can mail your drop bags to you after the race for $15 per bag.
Offline Course Maps (Avenza)
Avenza Maps offline course map logo

Now you can use our maps offline with a gps-enabled device!

We plan to mark the course with such rigor that you should not need your own map to help you find your way. However, we have experienced blown down signs and vandalism in the past. We recommend downloading the free Avenza app (available for iOS, and Android devices) before the event. There you can find our uploaded maps that work without cell coverage.

Here's how:
1. Download the free app "AVENZA MAPS" to your smart-phone or tablet while your device is online. It’s compatible with iOS, Android, and Windows devices.
2. Open the app > Tap "Store" (Shopping Cart Icon) > Tap "Find Maps" > Search for the specific distance you would like to download.
3. Tap on the label on the map > tap "install" and the map will begin to download.
4. The map is now ready to use “offline”. Simply open the app, click on the Map and your GPS location will appear on the map.

Timing Requirements
Overall Cutoff Times

You must complete your race within the respective cutoff time, otherwise, you will receive a DNF. Your time begins when you cross the start mat, so pay attention to YOUR individual start time and not just your starting window when assessing your progress throughout the race.

100 mile, Overall cutoff - 36 hours
100K, Overall cutoff - 22 hours
60K, Overall cutoff - 13 hours

30K, Overall cutoff - 9 hours
Trail Half Marathon cutoff - 5 hours

Minimum Pace Times

Below is a timing guide to help you gauge your progress throughout the race. Beating these times during training will help you avoid a DNF. If you find yourself consistently behind these minimums, your chances of finishing before the official close of the race are slim. Finishing after the minimum pace time or outside of your overall cutoff time will result in a DNF. 

If you do not meet these minimum times, you may be allowed to continue the race at the discretion of race officials. Race officials will consider runner health, extraction resources/accessibility, grim reaper times, etc. to make this determination.

Don't Fear the Reaper!

Grim Reaper deadlines are cutoff times that result in a DNF and removal from the course if you miss the cutoff time. Even if missed by one second, these deadlines are non-negotiable and exceptions will not be made.

A race official will be onsite to ensure all runners are past checkpoints before the Grim Reaper. You must EXIT the checkpoint before the posted Grim Reaper time to beat it. These cutoff times are shown in the cutoff sheet.

Competing for a Top Finisher spot?

While qualifying times are based on chip time (the moment you cross the start mat), overall top finisher awards are based on gun time. If competing for a top spot, you will need to be at the start line at the beginning of your race's 20-30 minute start window.

When competing for these top spots and starting before the official race start, you will have more of a buffer to beat aid station cutoff times. This does not mean that you have more time to complete the overall race. Regardless of when you start, you must complete your race within the allotted overall cutoff time (i.e. 30 hours).

Track Your Runner
Live Updates (Not Available)

Due to the remote location of this race, we will not be able to provide live updates for your friends/family. We do have satellite phones and/or radios at the aid stations so that we can account for runners on the course and keep communication lines open among our staff members, but we do not have the ability to communicate runner whereabouts to your loved ones during the event.

On Course Calls & Texts 

If you would like to let friends and family know your status on the course, you can text them from the areas of the course with cell service (there are many points on the course where reception is good enough to get a text out, but it can be difficult to get a phone call out.)

Carry an External Battery Pack (Or Two!)

We highly recommend that runners, crew, and/or pacers carry an external battery pack with them to make sure your devices don't die during the event. Cell phones and trackers are key to your communication and safety, so don't neglect them.

If you're worried about your cell phone battery, you can turn it off after sending a text or leave it in airplane mode to extend the battery life.

Rules for Race Day
Please review these guidelines so you know what to expect during the race!

Course Marking
For course marking all distances/courses will be marked with pink flags and ribbons. Any tricky junctions will be marked well with signs and flour arrows. A piece of highly reflective tape is attached to each trail marker that may be encountered at night.

Checking in at aid stations
It is the responsibility of the runner to check in at each aid station (coming in only, no need to check out of the aid station). Seek out the aid station worker wearing the fluorescent orange vest and give them your bib number. Failure to check in at an aid station can result in disqualification. If you drop out of the race YOU MUST TURN IN YOUR BIB TO THE NEAREST AID STATION CAPTAIN. If you fail to do this, you will be responsible for all related search party costs.

Timing Checkpoints
Depending on which distance you are running, you will find checkpoints at the following aid stations: Goosebump, Wire Mesa, Virgin Desert, Smith Mesa, and Guacamole Aid Stations. We will have a short corral that all runners MUST pass through upon arrival at the aid station on each pass. Failure to do so will result in disqualification from the race. 

Any runner dropping out of the race MUST hand their bib over to the aid station captain where they are dropping. Failure to do so will result in a 2 year suspension from all Vacation Races events.

At each aid station there will be a tent with self serve medical items like bandaids, salt tabs, etc. We will have trained medical personnel at the finish line as well as at select aid stations on course. If you find yourself in an emergency, call 911. You will be personally responsible for any costs associated with medical dispatch. If the problems are not urgent, please contact race personnel. We are equipped to respond quickly to problems on course that are not life threateningly urgent.

Due to the remote area of where the races run, this is not a very spectator-friendly event. The course and trails purposely get runners out into desert solitude while offering fantastic views of Zion. There are only a few spots to watch and cheer on runners. Virgin Desert A.S. and Virgin BMX Aid Station are both good places. Please be courteous and cautious while driving to these locations as runners may be on the same road that leads to the aid stations. Also, check with HQ before trying to access these locations if precipitation occurs. Of course, the finish line is one of the best places to cheer on the finishers.
