Trail running course through mixed terrain in California, USA

Half Marathon

5,249 ft gain

The courses utilize the extensive trail network within Redwood Regional Park and the adjacent EBMUD Southern Watershed. Runners navigate a mix of technical singletrack and wider fire roads, with the terrain varying from peaceful redwood groves to open chaparral and grassland sections. The hills are notably steep and challenging, with hiking poles permitted for those who choose to use them. Course marking follows Inside Trail Racing's comprehensive system using colored surveyor ribbons every 200 meters, with heavy marking at turns and laminated signs at critical sections. Blue ribbons specifically indicate wrong-way trails, serving as important navigation aids on this complex trail network. The varied terrain and elevation profiles make this a technically demanding course that rewards careful pacing and navigation skills.
