The Thacher Park Trail Running Festival, produced by ARE Event Productions, was created in 2014 in conjunction with the Thacher Park Centennial Festival.
It truly is a gorgeous course. (Check out these pics.) We welcome you to enjoy the park's beautiful and tranquil scenery on a summer's day by participating in either the 10K, 13.1M, 26.2M or 50K.

A festive atmosphere and AWESOME post race food! There are also medals for the finishers in the 26.2M & 50K. Do note that there is not a physical item giveaway.
Held at 6pm every Monday at Thacher Park until race day. Get the full scoop here.
While you may have them on-site at the event, you are not permitted to participate with pets or strollers.
Help us make it happen! To better accommodate volunteers, we have divided the event into 3 different volunteer shifts of only a couple of hours each.
All races start and finish in the same place in front of Hailes Cave Pavilion. Additionally, all races start together at the same time (8:30 AM) heading north and completing the exact same first 10K loop. Please refer to this animated course map to see it in motion.
The 13.1M, 26.2M, and 50K then continue to the south side of the park and complete a loop there. All three of these races run through the finish area at 13.1M.
The 26.2M and 50K runners then repeat the entire course again. The 26.2M and 50K runners come through the finish at 26.2M, with the 50K runners then going back out for a truncated version of the previous 7 mile section on the south side of the park.
The following cut-offs are in place based upon the event's volunteer, logistical, and safety plans.
Due to trail changes within the park, the course had to change for 2025. In addition to the modified courses, the event is now staged from Hailes Cave Pavilion (roughly a half mile from the previous location).
The 2025 courses and water stop locations are now posted.
A comprehensive email will be sent on Wed with full race details.

All races are run together. Everyone runs the same first 10K. From there, all doing the 13.1+ continue together to complete the 13.1.
Upon completing the first 13.1, those in the 26.2/50K then repeat the 13.1 course again.
Upon completing 26.2, those in the 50K then do the 'baby loop', which returns them to repeat a truncated version of their previous 7 miles.
YOU MUST SUPPLY YOUR OWN BOTTLE. THIS IS A CUPLESS TRAIL EVENT.
Nuun is available at all locations except for A and C. These are the full service aid stations, which also include gels and other snacks.
