ABOUT THIS RACE:
Race Starting Location:
Estrella Mountain Regional Park, Goodyear, AZ
The Coldwater Rumble Trail Runs is a Running race in Goodyear, Arizona consisting of a 52K Trail Run (Ultra).
The Coldwater Rumble is the fifth race in the Aravaipa Running a Desert Runner Trail Series, Arizona's premier trail & ultra run series. Trail Series = 20 mile | Ultra Series = 52 Km, 52 Mile
The course follows desert trails that wind through the foothills of the rugged and jagged Sierra Estrella mountain range. Many trails at Estrella Mountain Regional Park have recently been re-worked and there are several new miles of trail in use for this new course. The 100 mile race will feature five 20 mile loops.
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.
Additionally, it is important to understand the layout of your race given the awashing machinea style where you change directions after each loop. Specifically, our start/finish headquarters is and out-and-back of about 250 yards where you'll cross the timing mat, hit the aid station, drop bag, crews, etc. and head the same direction towards the paved road that you just came from. Your decision point will be at this paved road intersection where you'll need to know which loop you're on to decipher whether to go on a clockwise loop or counterclockwise.
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 just before the Pederson Aid (clockwise direction) 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 52M runners):
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.
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 and climbing the first hill in the first A mile.
The moon will be illuminating at about 40%, peaking sometime around 9 p.m.
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.
52 Mile & 52 Km Runners
This is VERY IMPORTANT so please read: You will both be completing a 20 mile loop (or two for 52M) to begin your race and then are asked to finish the 20K loop. Each year I have a handful of runners afinisha their race short on mileage. And each year it is because runners arrive at Coldwater Aid Station and then rather than doing the proper 4+ mile southern loop that brings you back to the Coldwater Aid Station, they skip it and head straight to the finish. Where I DQ them for cutting the course, intentionally or otherwise. This is your warning, please follow your signs and know your course.
