Pasadena Trail Half & 5K/10K : Pasadena Running Company
Pasadena Running Company presents the 2026 Pasadena Trail Half and 5K/10K as the final event in its 2026 Trail Race Series. The event uses the interconnected trails around Hahamongna Watershed Park in the Foothills of Pasadena, within the Angeles National Forest. The park includes oak woodlands, picnic areas, equestrian riding and disc golf, and the watershed basin contributes to local water conservation.
Three distance options are offered:
- 5K (3.12 mi) mixed use truck trail, +306 ft elevation
- 10K (6.2 mi) mixed use fire roads, +400 ft elevation
- Half Marathon (13.12 mi) single track rocky terrain, +1855 ft elevation
Each course is professionally marked and supported. At least one aid station is provided on every distance with water and electrolyte; longer courses will include CLIF products. All participants running over 5 miles are required to carry personal hydration. The event is electronically chip timed and offers free downloadable race photos.
Additional logistics include early packet pick up the day before at Run With Us Pasadena and free on-site race day parking. Registrants receive a race shirt and tote bag, a 2026 commemorative wooden medal made in the USA, a goodie bag with sponsor items, warm-up and cool-down yoga sessions, free training plans from Pasadena Pacers, and post-race fruit, breads and drinks.
