Coloma River Run – 5K, 10K and 10 Mile Race


Join JDRF and Coloma River Races for an exciting, scenic journey through the trails at Magnolia Ranch in Northern California! The 2019 Coloma River Run promises a unique adventure across stunning trails and breathtaking terrain. With all proceeds directly benefiting T1D research, it’s a wonderful opportunity to support a great cause while challenging your own limits.

This event truly offers something for everyone, regardless of background and ability.  Choose from three different races for a personalized trail experience. The 5K race is relatively flat turning left along the Gerly Loop, while the steeper 10K and 10-mile races climb the connector trail and wrap around Conan Ranch. All three runs begin at 8:00 a.m. from the Magnolia Parking Lot, located off Highway 49 in the Cronan Ranch Trail Area. Please note that dogs and strollers are prohibited from all three routes.

Coloma River Races was founded by JDRF Board Member Roger Leasure and his wife Salena. They were inspired by the beautiful landscapes of Coloma and wanting to do more for their two children living with T1D and thousands more, just like them.
