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 for 11 miles, passing under I-5 on the bike path, turning left on sorrento Valley Rd and finishes at approx 11300 Sorrento Valley rd. 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 2024. Get your end-of-the-year PR!!!
