Welcome to the annual Arnold Rim Trail Endurance Runs produced by Pacific Coast Trail Runs in conjunction with the Arnold Rim Trail Association, White Pines Park Committee, Calaveras Visitors Bureau, Vallecito Union School District, the US Forest Service, and surrounding communities. There will be 4 events, the 37 miler, half marathon, 10K,and the just recently added “point-to-point” 22 Miler because ARTA built another 4 miles. The 37M, Half Marathon, and 10K will start and finish at White Pines Lake Park. The 37 miler runs to the Heliport Aid Station and back on the Arnold Rim Trail. The half and 10K are also out and back courses. The half marathon turns around at Cougar Rock Aid Station and the 10K turnarounds at Post #8 Aid Station of the Arnold Rim Trail. While mostly single-track and under the canopy of many different trees, we can safely say that this multi use trail (Horse, MTB, Hiking and Running) is more like a double wide single-track for ease of use. Arnold, at 4,000 feet of elevation, with pristine trails that have been well manicured, and amazing support from the community, we are ready for our next adventure with you.
6 years ago, while visiting family in Angel’s Camp, I stumbled upon the Arnold Rim Trail on my phone. I somehow convinced everyone in my family that we must go see this trail the same weekend. Pulling up to the Sierra Nevada Logging Museum, Jenny and I immediately went to the trailhead and saw a map on a kiosk. Then, we noticed there was a group of people that were responsible for making this happen – more than a group, a community.
Thank you Arnold Rim Trail Association (ARTA) for helping us get to the start line. Together, we will all get to the finish line. In 2007, when ARTA had the first meeting, they have set the standard for coming together with city, county, state, and federal officials to make this trail something special. And, they have more trail to build. For years to come, we look forward to creating something special with all of those that are supporting this event.
37 Miler Description
The 37 Miler is a true out and back on the Arnold Rim Trail that turns around at the Heliport Aid Station. Mostly single track that has been groomed for your enjoyment. You will enjoy old and new growth under the canopy: Pines, Firs, and a few Sequoias as you pop out to check out some amazing views. Take your time, and you can enjoy some 360 degree views of the Sierra Foothills. For those than ran the 37 miler the 1st year, please note that we are not going to use the ALT- Arnold Rim Trail section. The race will now be on the “original ART” section that heads toward the San Antonio Falls.
