The course: The course consists of single track trails, rocky and rolling jeep trails, and dirt roads. The 100-mile course is the same as the 50-mile course but done twice, and the 50-milers start at the same time as you.
The route has some rough single track and also some nice single track trail, and some challenging climbs. There is approximately 14,774′ of climbing for the 100 miler (since it’s an out & back course there’s also approximately 14,774′ of elevation loss for a total of 29,548′ of elevation change). The course will be well marked with flagging and reflective tape at night.

Aid Stations: Located every 4.5-9.5 miles and stocked with electrolyte drink, warm food, and all the goodies you’ll need. They have all the supplies that you need to keep you on the trail. You can also have a drop bag waiting for you at Sapillo and the Start/Finish which is the half way point. To see the updated chart with detailed info about each aid station, please click HERE.

Drop Bags: There are two drop bag locations available for the 100 miler, but you will pass by these locations 3 times:
The “Start/finish” area (which is also the 50-mile turnaround),
And Sapillo Campground which you will access 2 times at miles 25 and 75).
There will be a drop bag drop-off area at the start line on race morning, and they will be transported to the designated A/S for the runner. Please make sure that the runners name, bib number and aid station name is clearly written on each drop bag (“Sapillo” or “Start/Finish”).
We will do our best to get drop bags back to the finish line ASAP but we can’t guarantee how long it will take. If you drop to the 50-mile race you may have to wait a while for your bag to come back from Sapillo.

Cut-off: the 100-mile race will end at 6:00 pm on Sunday (a 36-hour cut-off). Cut-off times will be adhered to. See the aid station chart for cut-off times.
This is definitely not an easy course and is underestimated. It is strongly recommended that those who enter the 100-miler have completed at least one difficult, mountainous 50-miler and have trained properly for the hills and weather, or they will have a hard time and likely not finish.
There is no qualifying race for Gila 100 so please be prepared.
When a runner gets to an A/S and feels that going further is not an option it is best to just sit down, eat, and drink. Having a pacer that runs the second half of the race with you may help you complete the race. As a last resort a runner always has the option to DNF and can catch a ride back to the finish from an A/S volunteer but you will likely regret it. If a runner does end up dropping from the race it is extremely important that the runner informs the A/S captain or RD and turn in their bib.
Runners cannot leave the course and return. If a runner leaves the course they will be disqualified.

Pacers: Pacers don’t have to register. They can get their bib at Open Space Brewing during packet pick-up the day before, or they can get one at the start/finish after the race has started.
Each runner can have one pacer at a time to help them complete their run. Pacers can enter the race only after their runner has reached the 50-mile turnaround at the Start/Finish. They may also join their runner at the only crew-accessible aid station after 50-miles (Sapillo Campground). It is important to let the aid station volunteers know where the pacer is meeting the runner and for how long the pacer will be with the runner so we can keep track of all of those on the course. Pacers may eat from the aid stations, but remember it’s not a free buffet, the food is there for the paid entrants. Please plan on bringing some of your own food too!

Crews: The only crew accessible aid stations will be: Start/Finish and Sapillo Campground. This is a backcountry adventure; crew is NOT allowed to meet their runner at any other location. Runners that fail to follow this rule will be DNF’d.
Weather: The weather during the Gila 100 is anything but predictable. It’s true that the course is quite hilly with rugged sections, but the weather is the main cause of our high DNF rate. It can range from a beautiful sunny and 85 degrees, then plunge to 35 degrees at night with 40 mph winds, rain, and hail conditions. It’s VERY important that you come prepared with proper clothing and attitude.

Awards: All finishers will receive a custom 100-mile belt buckle and RNNR hat.

Course Map: The race is 2 trips on a 50-mile course. A link to the overall map of the 100-mile course that can be found on your main Gila 100/50 Race page. 

RULE CLARIFICATION: 100-mile runners that drop down to the 50-mile distance ARE NOT eligible for podium finishes.
