Coldwater Rumble

The Coldwater Rumble Trail Runs take place at Estrella Mountain Regional Park in Goodyear, Arizona, featuring multiple distances including 100 miles, 100K, 60K, 40K, 10 miles, and 5 miles. The courses wind through desert trails at the foothills of the rugged Sierra Estrella mountain range, offering scenic views and a mix of trail surfaces such as single track, rocks, sandy washes, and old jeep roads. The event is part of the Desert Runner Trail Series and includes well-stocked aid stations, chip timing, and finisher awards.

Runners should prepare for significant temperature swings and night running. The race promotes environmental responsibility with cupless aid stations and encourages volunteer participation. Visit the organization's website for the most recent information.
