COURSE INFORMATION

Courses
All courses feature a wide variety of typical desert trail running surfaces including crushed granite single track, rocks, boulders, sandy washes, old jeep roads, and dry wash beds. Be prepared for a wide variety of conditions from very well defined, to more remote and sandy. Course Photos

The course itself sits at the foothills of the virtually untouched, rugged, mountain range known as the Sierra Estrella Mountains that will provide some gorgeous backdrops throughout your journey. I guarantee at some point during this race you’ll be drawn to these peaks. You will mostly be running on rolling single and double track trails without any real substantial climbing in one shot. There is a 1.5-2 mile section on the back half of the course named the Corgett Wash and can be very sandy depending on the weather leading up to the race. This is a great race to consider gaiters because of this.

Hiking/trekking poles are not quite as useful but are allowed.

A couple other points to consider with this race (more specifically 100M and 100K runners):

  1. Keep in mind that we can have some pretty dramatic temperature swings from day to night (30-40 degrees). You may be running through the day with a headwrap on to protect yourself from the heat (see: zero shade cover) and then bundling up to stay warm through the late parts of the night. I know, 40 degrees is nice where you’re coming from this time of year. Trust me, it’s a cold 40 degrees here and running in and out of the washes on course you’ll understand.
  2. As it is the middle of winter, there will be a long period of night time running. Do not get caught out on the trail between aid stations without a headlamp! Bring an extra and be prepared to run through the night from 6pm until after 7am. You will begin your race just as civil twilight hits the horizon so it’s possible to start your race sans headlamp but it’s your call- you’ll be on a trail 100 yards into the race. 
  3. For those of you joining us after running the Javelina Jundred 100 miler in October, you’ll see there are two additional hours to finish for Coldwater. The terrain is more technical, the night longer, and we want you to finish this thing. Keep Going.

Trail Etiquette

Under no circumstances is it OK to yell at or be rude to a volunteer or staff member. Do not rely on volunteers, photographer’s or other staff persons to direct you on your course. It is YOUR responsibility to know your course and follow the course signs. If we get word of this occurring, we reserve the right to DQ you from the race. These people are volunteering their free time to assist you in reaching the finish line and are doing everything they can to get you there. Thank them and keep moving.

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 or a road crossing.
Please do not listen to music on course without headphones.

Hiking poles are allowed. Please be conscious of where you’re pointing them.

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.

Photography
To capture both your pain and euphoria along the way, we will staff out on the course. With our crew, you get photographers who are also runners and understand what your race photos mean to you!

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 after each lap will be displayed on a screen at the finish line turnaround.

We will also be placing remote timing points on the course making it easier for crews, friends, and families to follow you on your journey! To access the live updates, visit this link: live.aravaiparunning.com, on race day and click on Coldwater Rumble.

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: Coldwater Rumble Volunteer Form

Course Markings
The race courses will be well marked with orange plastic ribbons with black polka dots as well as orange pin flags with the Aravaipa Running logo on one side. Trail junctions and turns will be well marked with colored laminated. 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.

Parking / Start Area
The 2024 start/finish line is located at the Estrella Mountain Competitive Track. There are plenty of parking spaces within the start/finish area and the surrounding satellite lots.
