The race is set inside Quarry Lakes Regional Recreation Area and heads out along the Alameda Creek Trail toward Niles Canyon. The trail is paved and flat the whole way, with the creek and open space on either side. Several distance options make it a frequent choice for people chasing a personal best.
Packet pickup is race-morning only, at the Ensenada Pavilion inside the park. Plan to arrive with enough time before your wave goes off.

The ZombieRunner Quarry Lakes has been held every year since at least 2021. That is as far back as RunSignup's records for this race go, so it may well be older.

How we calculate these stats: RunSesh calculates these figures from the most recent published results of past editions, sourced from RunSignup. We show aggregates only: field size, winning and median times, and the cutoff. We never publish individual finisher tables. Last updated Oct 25, 2026.
Set a goal and get a pace band: every mile split on a card sized for your phone lock screen, so race morning needs no math.

Almost certainly not. Half the 13.1 Miles field finished slower than 2:12:12, and the last recorded finisher came in around 3:57:53, so there is a long tail of runners behind the middle of the pack. Most fields are far slower than people expect.
It is a small race (144 finishers), which is friendlier and less intimidating than a big-city event, though the field thins out. There is no qualifying time, and the finish-time spread above shows how varied the field really is. If it is your first 13.1 Miles, that spread matters more than the winner's time.
The 13.1 Miles winner ran 1:26:24 while the median finisher took 2:12:12. That spread points to a mixed field, with a competitive front and a big recreational middle.
