Calero Trail Run - Winter

Calero Trail Run (Winter)

Calero Trail Run is a trail running event held at Calero County Park in San Jose, California, with a range of measured distances and mapped courses. The venue name and a street address are provided for navigation to the park parking lot.

The terrain includes single track, dirt paths and uphill sections with oak trees and exposed viewpoints. The organizer notes panoramic vistas and conditions suitable for heat training on certain routes. Course markings use colored ribbons and turnaround signs to direct runners on out-and-back and loop sections.

Distances offered include:

• Kids Run
• 1 Mile
• 5K
• 10K
• 15K
• Half Marathon
• 25K
• Trail Marathon

Several courses list total ascent figures and specific navigation features. Examples from the event materials include course ascents such as 252 feet for the 5K, 1,187 feet for the 10K, 2,477 feet for the Half Marathon, and 2,726 feet for the 25K. The Half Marathon and longer distances use colored ribbon sequences to define loops and turnarounds. Aid and water stations are located at the Calero Start/Finish area and at the Rancho Cañada del Oro aid station; a single restroom is noted at Rancho Cañada del Oro.

Logistics include free parking at the Calero Park lot, on-course parking guidance for support crews, two drop bag locations for 50K runners, race day registration options, and a policy that entry fees are non-refundable with credits available for notified cancellations before race day.
