Half Marathon · 5K

From the Organizer

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 ‘real’ hill at mile 1.5), along the 56 bike path and finishes at the beautiful Torrey Pines State Beach (pictured above!). 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.

About This Sport

From Endurance Grid's Founder

Endurance Grid is here to help you understand the sport, decide if it's the right fit, and learn how to prepare. For course distances, logistics, and race-day specifics, always defer to the race organizer's event page.

The half marathon is the distance where you find out what you're actually made of. Long enough to demand real preparation. Short enough that it doesn't consume your life to train for it. Most people who run their first half describe it as the race that changed their relationship with what they're capable of. Once you cross this finish line, the bar moves. That's not a warning — that's the point.

Race day energy varies by event size, but the finish line feeling is the same regardless. Big races keep the noise going the whole way. Smaller races give you stretches where it's just you and the miles — and that solitude becomes its own kind of fuel.

The half marathon rewards people who show up for the boring training miles.

How long to train: 10–14 weeks. If you're already running consistently, 10 weeks of structured buildup is enough. If you're building from a casual base, give yourself 14.

Running
