Welcome to the 2nd annual Arnold Rim Trail Endurance Runs produced by Pacific Coast Trail Runs in conjunction with the Arnold Rim Trail Association, White Pines Lake Park, Calaveras Visitors Bureau, Vallecito Union School District, the US Forest Service, and surrounding communities. There will be 4 events, the 37 miler, half marathon, 11K,and the just recently added "point-to-point" 22 Miler. The 37M, Half Marathon, and 11K will start White Pines Lake Park and head south west towards Angel's Camp. The 37 miler is a true out and back course on the full length of the Arnold Rim Trail. The half and 11K are also out and back courses. While mostly single-track, 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.

Happy Friday, Runners & Hikers!

3 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. I then noticed there was a group of people that were responsible for making this happen -more than a group, a community. Since then, plenty has happened to all of us. Now, one week away, I am so excited to see this come to fruition.

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. 

Here is what to expect while on course. The recent Sierra foothills just got 4 inches of rain and should make for some very nice footing on perfectly groomed California Single-Track. Single-track trail wide enough for two-way traffic, you will enjoy seeing your fellow participants while running your event.

For those in the 11K, you will have a comfortable run under the canopy before turning around at the 3.4-mile marker - POST #8 A/S. Please make sure to thank those ARTA volunteers for making this all happen.
The half marathoners will be leveling up and continue on past POST #8 and head towards Falls Overlook on more technical trail. You will then pass Manuel Peak and Top of the World, before getting to Cougar Rock A/S. Once at Cougar Rock Aid Station, you will then go up 150 feet or so to the actual Cougar Rock to grab a "Cougar Rock ARTA/PCTR" bracelet. Return to aid station and then back to the finish line.
For those in the 37 miler, you will go to ART alternate before heading to Cougar Rock. After grabbing your bracelet at Cougar Rock, you will head down-ish hill to ASRR A/S and Heliport A/S. Since we launched registration for the race well over a year ago, we changed the distance from 35 to 37 miles as ARTA has built more trail which will you will now experience. PLEASE NOTE that the cut-off of 5hrs 15min is aggressive because the return trip to the finish line has a positive elevation gain compared to the downhill profile of the first 18.5 miles.
Reminder that since 2017 we have been cup-free. Please make sure you have a water bottle or portable beverage container to get hydrated while on course.

It will be very hard to be off course. Follow the orange both ways and you are sure to get to the finish line. We will use Orange Flagging and Ribbons to make sure you are on course. 11K turnaround at POST #8. Half marathoner’s turnaround at Cougar Rock, and 37 miler’s turnaround at Heliport. 


11K - Crew access by foot only.

Half - Crew access by foot only.

37 Miler - Crew access by vehicle at Avery Sheep Ranch Rd & Heliport Aid Stations.

Enjoy the rest of your evening and we will check back in on Sunday Night.

Go run a trail.

Welcome to a new era in race production with Pacific Coast Trail Runs. Our immediate goal is to bring you to new trails and new places with friendly faces. We can’t be prouder to bring an event to our new friends in Calaveras County.

It will be a perfect 78 degrees and sunny next weekend. Food Network Celebrity Chef Yaku Moton-Spruill and new PCTR partner will be ready to fill your bellies after the race. Shall you want extra meal tickets for your crew or family, please reply to this email and we can set-up payment options. $18 for Adults and $10 for youth. We always have vegetarian options.

Whether planning a day trip or weekend trip to Arnold and White Pines Lake and Park, please start to plan now and put these items aside or in your vehicle now.

Folding Chair.
Floating Device – Tube, raft, kayak, stand-up paddle board.
Bathing Suit.
Change of clothes and a positive attitude.
For you day trippers, please plan enough time to drive from Nevada or California as the roads are mostly one lane each way for the last hour of your trip. Registration opens Saturday morning at 5:30am for the 37 milers and 9am for the Half Marathoners and 11K participants.

The staging for the start-finish line is amazing. We will be 10 feet from the shoreline of the lake and you will find it soothing before or after your race. Plan on getting in the water to cool down and play under the sun.

Huge thanks to the Arnold Rim Trail Association, Calaveras County Visitors Bureau, Calaveras Amateur Radio Society, Ebbetts Pass Fire District, Gateway Press, El Vaquero Mexican Restaurant and Hinterhaus Distillery for sharing your playground with us.

You may event wish to rent a mountain bike or e-bike from Mountain Aloha (Avery, CA) or Bear Valley Bikes right in Arnold.

For those traveling far, I would get on or and start looking for a cozy cabin to relax in for the weekend. Before checking in to your cabin or motel, make sure you go by the lake Friday Morning to see the start – finish line area. Perhaps you spend a few hours at the lake or nearby Sierra Nevada Logging Museum. Perhaps you head back to nearby Angels Camp or Murphy’s towns to catch up on your gold rush history. Did you know about Mark Twain and Frog Jumping? Calaveras Big Trees? Ironstone Vineyard and concert venue? There are so many cool things to see around your race.

Here is the PCTR race week itinerary:

Thursday AM arrival
Thursday 4pm to 6pm– Hinterhaus Distillery for a drinks and snacks
Friday AM – Course marking with the Arnold Rim Trail Association
Friday 4pm to 6pm - Come by El Vaquero Authentic Mexican Restaurant

That’s all for now and I will check back in tomorrow with more news about the race.

Thank you, kindly.
