Welcome to the 9th 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.
53 Km: Runners will now get to head out of the Fort Tuthill County Park early on heading west on the Rodgers Lake Connector Trail and looping back on the Powerline Trail to Sinclair Aid. Returning into the county park, you’ll follow the Soldiers Trail to the Highlands Trail & Highlands Aid. Once connecting back with the Soldiers Trail, you continue all the way to the northern end of the park where you’ll hop on the Flagstaff Urban Trail System (FUTS TRAIL) heading north out of the Tuthill Park. This will bring you back to Sinclair Aid around the halfway point in your race. You’ll again follow the course within the County Park to Highlands Aid but this time following the Soldiers Trail all the way back to the the start/finish area around mile 24. Here you can pick up a pacer, access your drop bag or crew and head back out for the final 13Km loop to complete your ultra in the pines.
Aid stations every 4.0 to 7.3 miles including water, electrolyte drink (Gnarly Fuel-2O), sweet snacks, salty snacks, and fruit. As it can get hot and you’ll be running at elevation, please plan to run with at least one bottle of water.

Address
Fort Tuthill County Park
Flagstaff, AZ 86001
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
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 will have medical staff based at the start / finish headquarters. This team is here to help you with most basic and advanced first aid right on site. We reserve the right to pull you from the race if medical officials deem it necessary. Please understand that these decisions are made for your safety and do not argue. Continuing on in a state where you cannot safely navigate is a recipe for disaster and we are here to prevent that.
NOTE: If something happens to you or another runner, do NOT call 911 right away. Our medical team is highly trained in these scenarios, has been with us at this race the last three years and understands the terrain and driving access points. Please call their 24-hour number that will be answered by a real human being and they will dispatch accordingly.

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.
Pets
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 or in aid stations.
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.
Results will be posted using Gun Time.

Awards
Awards to the top 3 male & female finishers at each distance.
All finishers will receive a race branded campfire mug or a wooden Artworx finisher award
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
We also hold Blackout Night Runs at this park the same day as Big Pine. Finish any distance at both races and receive a unique custom medal for completing our Double Down! Races for Blackout Night Runs begin at 7 p.m. on Friday and include a 6KM , 13 KM, and 27KM.
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 21-23 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!
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!
Our Aravaipa Group Campground is conveniently located just a short walk from the start/finish area under the pines. There will be water access and portable restrooms available. Parking for your vehicle is very close to the group camping area, but you will not park your vehicle AT your tent. There are no designated spots in the group camping area and all tent locations will be first come, first serve.
There are only a limited number of permits available this year so plan ahead as we anticipate it selling out!. Tent camping passes are $35 each and include both Friday and Saturday nights.
The camping area opens Friday, June 21 at 2:00 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 Group 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 21. Tents will be checked into on a first come, first served basis.
