Saturday, December 20th, 2025
The San Diego Holiday Half Marathon is a fast 13.1-mile course that starts on Penasquitos Drive in front of the Hotel Karlan (formerly, the Doubletree Golf Resort) then travels SW along Carmel Mountain Rd (your only โrealโ hill at mile 1.5), along the 56 bike path and finishes at the beautiful Torrey Pines State Beach. The race includes a 711-foot net elevation drop along the โrollingโ downhill bike path, which also makes it a personal best candidate. This popular winter half has been a sell-out event every year.
