Race Info

The San Diego Holiday Half Marathon is a fast 13.1 mile course that starts on Penasquitos Drive and Carmel Mountain Road, then travels SW along Carmel Mountain Rd (your only ‘real’ 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 “rolling” downhill bike path, which also makes it a personal best candidate. This popular winter half has been a sell out event every year and sure to sell out for 2023. Get your end of the year PR!!! Source
