Timing
All races will be professionally chip timed with a disposable timing chip attached to your bike bib. Please attach to your handlebars on the front of your bike. Live results will be available during the event at Aravaipa Live

Course Marking
The race courses will be well marked with orange plastic ribbons with black polka dots and reflective medallions. Trail junctions and turns will be well marked with reflective laminated signs. In addition, blue & white checkerboard plastic flagging and RED reflective WRONG WAY signs will be hung to designate non-race or “WRONG WAY” trails. All riders are responsible for understanding the layout of the course. Please familiarize yourself with the course maps on our website prior to race day and/or print a map to bring along with you.

Aid Stations
In addition to a well stocked drink and feed station at the start/finish line at the San Tan Trailhead Area, there will be one water and electrolyte remote aid station located along the San Tan Trail.

Cutoffs
In order for your final loop to count you must cross the finish line before your 3 or 6 hour time limit expires. We will have a final loop cutoff where you can head out on your loop no later than a certain time:
10:00 PM - 3 Hour Final Loop Cutoff
10:30 PM - 3 Hour Race Ends
12:30 AM - 6 Hour Final Loop Cutoff

Duo Teams
We will offer a duo team option for the 6 Hour race. 6 Hour Team participants are comprised of two riders on a single team who complete laps one at a time for their team. You decide who rides which laps and how many. Riders may elect to ride more than one loop in a row, but switching between riders may be done only in the transition zone at the start/finish area.

Drop Bags
We will have an area specified for your personal drop bag at the start/finish area that will allow for easy and quick access. Feel free to setup your own coolers and chairs in designated areas.

Camping
Camping is allowed by San Tan Mountain Regional Park for this event in their dirt parking lot as long as you purchase a camping permit here. One $15 camping permit will be good for one truck / van / camper for the night of the race.

Mountain Biking and Trash
Please respect the trails and the beauty of the desert by disposing of any trash at one of our aid stations. We do recycle and participate in the Terracycle program where we recycle used nutrition packets and gel wrappers. Please deposit them in the specified container at the feed station.

Trail Etiquette
Remember to always remain on designed trails, no short cutting.
Headphones are not permitted. No E- Bikes.

This course includes some legit single track. If you are fast and attempting to pass, please alert the rider in front of you before flying past them. Likewise, if you hear a rider approaching you from behind, attempt to find a spot to allow the pass once it is safe to do so.

As a general rule, when passing a rider, announce, “on your left.” Remain in control and respect the other participants.
Everyone is after the same goal here so let’s be respectful of each other’s races and have fun.

Pets
For the safety of all runners, no pets are allowed on-course at the night races. Any pets at the race must be on a leash at all times, respect park rules, and be supervised.

Volunteers
If you would like to join our volunteer team, we are looking for help with event setup, aid station, and event breakdown. Volunteer perks include a piece of Aravaipa merchandise or race goody and Aravaipa Race Credits. Sign up to volunteer here!
