Course Summary

Welcome to the 6th annual Big Pine Trail Runs at Fort Tuthill County Park! Runners will get to experience both the Soldiers Trail and Highlands Trail Loop (6 Km runners will only run on a partial Soldiers Trail loop) which winds through the ponderosa pines above 7,000 ft,  eventually topping out on a mesa with expansive views of mountain landscapes before being enveloped back into the trees. The trail ranges from narrow single track to wide well-maintained forest paths. The course is well graded for beginners while allowing the more experienced runner to stretch their legs and gun for a fast time while still maintaining the challenge of being at a higher elevation. The course is designed as a multi-loop race with the 54 Km doing 4 full circuits (27 Km = 2 loops / 13 Km = 1 loop).


Expect hot conditions during the day (we typically see temps into the 80’s) and cooler night-time temperatures (expect low 40’s)! In other words, if you are driving up from Phoenix to escape the summer heat you should prepare for warm and down-right cold! Forecast for Flagstaff, AZ

Bib/Shirt Pickup

*Friday will be the only packet pickup prior to race morning and will be available from 6pm-11pm during our Blackout Night Runs.

Flagstaff Extreme Adventure Course 

Up the ante for the weekend with a go at the Flagstaff Extreme Adventure Course conveniently located at the start/finish. Flagstaff Extreme offers both Adult and Kid (ages 7+) courses. You will receive a 25% discount on passes purchased through ultra signup at registration or they may be purchased without registering for the race here. Passes will be good for the entire year and do not need to be used race weekend. In fact, if you want to experience it all on June 12-13th you will need to purchase tickets soon as we only have a very limited number of passes to offer and time slots always fill up quickly over that weekend!

Back in 2020, you can also purchase discounted passes to the Adventure Ziplines course (12 years and up) that includes more than 30 exhilarating zip lines suspended in the Ponderosa Pines on what is now the largest zip line course in the western United States!

Crews & Pacers

Crews are welcome to support runners at the finish line.

Pacers are allowed for the 54K for the 4th (last) loop (41K). Pacers are not allowed for any other distance.


Awards to the top 3 male & female finishers at each distance.

All finishers will receive a finisher award (2018 award pictured).

Trail Running & Trash

Please respect the trails and the beauty of the forest by disposing of any trash at one of our aid stations.

Trail Etiquette
Remember to always remain on designed trails, no short cutting.
If you decide to use headphones, please be respectful of runners behind you attempting to pass. Also, remove ear buds as you approach aid stations, volunteers, or a road crossing.
Please do not listen to music with a speaker (yes, we know you listen to the best music).
This course includes some legit single track. If you are fast and attempting to pass, please alert the runner in front of you before flying past them. Likewise, if you hear a runner approaching you from behind, attempt to find a spot to allow the runner to pass.

As a general rule, when passing a runner, announce, “on your left.”
Uphill runners/hikers have the right of way to downhill runners. Remain in control as you descend and respect the other runners.
Everyone is after the same goal here so let’s be respectful of each other’s races and have fun. Please.


Dogs are allowed at the race headquarters (and campground) and must be on a leash at all times and not left unattended. No dogs are permitted on the race course.

Race Timing

We will be utilizing a chip timing system at this event to record your time at the finish. You will be provided with a timing chip attached to the back side of your race bib. It is important to not crease, or fold the the timing chip to ensure your finish time is read.

Drop Bags

A drop bag will be allowed at the start/finish area and will be available to runners on each loop.

Aid Station Helpers

We cannot produce these trail runs without the help of our amazing volunteer team. You can even help and run on race day. If you would like to join our volunteer team, we are looking for help with event setup, aid station captains, aid station helpers, timing, photography, videography, social media and event breakdown. Volunteer perks include a piece of Aravaipa merchandise or race goody and Aravaipa Race Credits. You can see our current opportunities and sign up here: Big Pine Volunteer Form

Course Markings

The race courses will be well marked with orange plastic ribbons with black polka dots. Trail junctions and turns will be well marked with colored laminated signs. Please pay attention to these signs at each junction as there are multiple race distances and race courses! In addition, blue & white checkerboard plastic flagging will be hung to designate non-race or “WRONG WAY” trails. All runners are responsible for understanding the layout of the courses. Please familiarize yourself with the course maps on our website prior to race day and/or print a map to bring along with you.

We are excited to offer several camping and tent rental options at the 2020 Flagstaff Extreme Big Pine and Blackout Night Runs. Aravaipa Running has reserved the entire North Overflow camping area right by the start/finish. Tent camping passes are $35 each and include both Friday and Saturday nights. The camping area opens Friday, June 12 at 12:00 PM for camping setup.

NOTE: This is a tent only camping area. You will park your vehicle in the parking lot just behind the tent area that is easily accessible.

Pets: Dogs are allowed in the camping area but must be on a leash at all times and not left unattended.

Tent and cot rentals will be available for your convenience. These will be located at the same North Overflow camping area directly next to the start/finish. You may reserve a tent and/or cot when you register for the race or reserve one directly here.

All rentals will be setup when you arrive, so all you have to do is bring in your sleeping bag and gear and you will be all set. You may check in to your tent anytime after 2:00 PM on Friday, June 12th. Tents will be checked into on a first come, first served basis.

Small Tents – These are 7 feet by 7 feet, a simple two person camping tent that is tall enough to sit up in, but not to stand. Cot rentals are not available for small tents.

Large Tents – These are 8 feet by 12 feet and are large enough to stand up in (for most people) and may also fit two cot rentals.
