Grand Canyon

Friday-Saturday, May 15-16, 2015 – Grand Canyon 100 mile / 50 mile / 50k


The combination of the rugged, remote area and buffed single track trail make this a uniquely runnable course through ponderosa and aspen forest, while showcasing the intense beauty of the Grand Canyon. It will be a test of your ability to keep your eyes on the trail as the canyon’s views demand your gaze while you skim along the rim high above the canyon floor.

In addition to the standard fare, any night aid stations will have different warm food items such as broth (vegan), ramen noodles, rice/bean/cheese/salsa burritos, grilled cheese, quesadillas, coffee, hot chocolate, and pancakes/eggs/bacon in the morning.

Birthday cake will be served at the Parissawampitts aid station, celebrating all of the runners with May birthdays!

We are so pleased to have the great Turd’l Miller overseeing all aid station operations at each of our events this year, bringing runners back from the dead left and right!


Crew access is allowed at any of the aid stations. Click here to view more detailed aid station information, including directions for crew/pacer access. Pacers are allowed for the 100 mile after the first lap on the course, and can be switched out at any aid station thereafter in the race.  50 mile pacers can begin at North Timp aid.  No  pacers allowed for the 50K.


All UA events are zero waste, with less than 1% of the trash produced at the event going to the landfill (and no portapotty chemical sludge being sent to the wastewater treatment facilities.)

Here’s how we do it-

1-  We separate all organics/compostables as well as the normal recyclable materials at the start/finish line and each aid station.  Please help us to keep recyclables and compostables separate from the other trash.  We will have labeled bins at each location.  We have an Ubuntu Blox machine that compacts our non-recyclable trash into bales which are used as a sustainable building material.  The beauty of the Ubuntu Blox system is that it provides a use for the non-recyclables such as wrappers, plastic bags, etc.  With this system, we were able to “upcycle” nearly 100% of our landfill bound solid waste.

2-  Eco Commode composting toilets. All human waste collected is composted after the event, becoming a nutrient-rich soil amenity as the end product.  You will find a bin of cover material next to each of the toilets at the event.  Please add a scoop or handful of cover material after each use of the toilet to keep things fresh for the next user and to help maintain proper carbon/nitrogen ratios.  This cover material is usually sawdust, but can also be shredded newpaper, ash, peat moss, coffee grounds or another carbon source.

For more information about our Zero Waste system, see this blog post.


The pre and post race meals are artisan pizzas made to order. Runners will be required to present their bibs to the chef in order to get their free pizzas.  One pizza for 50k runners, two for the 50 mile runners, and 3 for 100 milers.  The pizza ovens will be fired up at runner check-in before the race and then for the duration of the event.  A beverage of your choice will be provided with each pizza as well.  For those runners that finish during the night or in the morning, we have some delicious breakfast and dessert pizza options for you to choose from.  Additional pizzas can be purchased by runners and crew for just $6.


The Kaibab Lodge is the nearest hotel to the starting line. The historic Jacob Lake Inn is also nearby.  Once these fill up, the nearest accommodations are in Fredonia, AZ and Kanab, UT.  There is plenty of room for free camping near where the race starts and finishes (we will have water and showers available for runners).  De Motte Park campground is located next to the Kaibab Lodge, about ten minutes from the starting line. Kaibab Camper Village is the nearest campground with full hookups.

GETTING HERE It is about 4 hours from Las Vegas to the Kaibab Lodge.  Zion and Bryce Canyon national parks are within an hour’s drive along this route if you’d like to take some extra time to explore. The approach from Salt Lake City is about 6 hrs and passes very near Bryce Canyon and the east entrance to Zion National Park.  It is about 4 hours from Flagstaff, Arizona and 5.5 hours from Phoenix.


We realize that these are destination races for most folks, and it may be the only time that you visit this uniquely beautiful area.  One of our biggest desires at Ultra Adventures is that you walk away from this event having fully experienced what the area has to offer.  Even a 100 mile course can only capture a portion of what this diverse topography has to offer.  We want you to get into and explore the heart of the national park, walk through that remote slot canyon, see that most amazing overlook that is not part of the course.  Most often, these spectacular areas are protected as part of a national park, monument, or wilderness area where large group activities are not permitted as part of the management plan.  These are often the areas most frequented by tourists, but  are nevertheless places that we feel you must see while you’re visiting.  It is our hope that these experiences will help you to become even more connected to the local landscape, thus creating more stakeholders in its preservation.

For each event, we have created a “Trifecta” list-  Boiled it down to 3 “must see” areas that are within a reasonable travelling distance of the race course.  For each of the 3 “legs” of the Trifecta that you complete, you will receive 10% discount credited towards the next Ultra Adventures event that you participate in!  Complete all three legs of the Trifecta and you have earned yourself 30% off of the next event!  These discounts can also be accumulated, so after 3 events, you can earn 90% off of the 4th event just for getting out and doing what you love!!

Trifecta Rules: To get credit for completing a leg of the Trifecta, you must submit a picture from each of the required locations of that particular leg of the Trifecta.  There is a two week window in which these pictures can be submitted- between one week prior to the event date until one week after the event has taken place.  Any pictures submitted before or after this time window will not be accepted.

Pictures must include:

1)  A clear view of your face

2) A clear view of your bib # (Race bibs will be assigned and available to view on 7 days prior to the event- if you visit one of the Trifecta sites prior to packet pickup, you will have to write your bib # on a piece of paper and have it visible in the photo.)

Pictures can be submitted in two formats:

1) Instagram- Use the hashtag #2015grandcanyontrifecta

2) Email the picture to

***Race credit must be redeemed within one year from the race date and the amount credited is based on the amount that you paid for the event that you participated in- (ie. for a $100 registration fee you would earn $10 credit for each leg of the Trifecta, for a $200 registration fee, you would earn $20 credit for each Trifecta leg completed).

The 2015 Grand Canyon Trifecta will be:

1) Bill Hall trail- (9 miles)This trailhead is very near the starting line, we run by Monument Point early on in the race.  Take a photo at the Esplanade section and turn around.  Attempting a rim to river trip is not recommended. Bring plenty of water, this trail is exposed. Click here for trail description 

2) North Kaibab trail- (9 miles) Run down to Roaring Springs, take a photo, and back up.  Click here for trail description.

3) Widforss trail- (10 miles) Take picture at the turnaround overlook at mile 5. Click here for trail description

***Other amazing options (which can replace any of the above trifecta legs but are not required due to price and/or distance):

South Canyon- You can take the UPS route (7.5 miles) or the traditional route (13 miles).  Take the photo at the Colorado River.

Rim to Rim(Or R2R2R) This can take the place of all 3 Trifecta challenges if done within a week before or a week after the race.


The belt buckles (awarded for the 100 miler finishers only) are each hand crafted using organic materials gathered on the course and preserved in resin.  The finishers’ award for the 50K and 50 mile distance is a hand thrown pottery mug.  Each of our awards is unique- you can choose the one that speaks to you.  Awards will be given to the top 3 overall male and female finishers for each distance as well. We hope that you will join us at the finish line for as long as you’d like to welcome home the other finishers.  One of our goals this year is to create a welcoming environment for you to hang out with old and new friends.  To make this possible, we will have the following amenities present at the finish line to keep you comfortable- shade, seating, pizza, drinks, hot showers, a wood-fired cedar hot tub, massage tent, recovery tent, medical tent, and a camping area.  We are so pleased to have the infamous “Whiskeytown” George Walsh (a.k.a. “GW”) overseeing the start and finish line operations at each of our events.


We are proud to offer one of the best refund/rollover policies out there.  The amount refunded will be determined by how much advanced notice you give us, since many costs involved with the race are incurred early.  If you notify us prior to 60 days before the race, you are eligible for a 100% refund or rollover towards any Ultra Adventures event.  If you notify us prior to 30 days before the race- a 75% refund or rollover will be issued.  If you let us know between 15-30 days prior to the event- a 50% rollover can be applied (sorry, no cash refunds issued within 30 days).  Within 15 days of the event- no refunds/rollovers will be issued.
