About the San Lorenzo River Trail Run

The courses here run through coastal redwood groves, stream canyons, open meadows, and dry chaparral ridges above Santa Cruz. Almost all of it is single track and dirt road, with no pavement to speak of. Every distance option crosses the San Lorenzo River more than once, and the climbing is real across the board, with elevation gain that builds significantly as you step up to longer distances.

Packet pickup and check-in happen race morning at Harvey West Park, at the Friendship picnic area. Parking there is free. Runners doing one of the longer distances can bring a drop bag with non-valuables to leave at the start and finish area.

Common Questions About the San Lorenzo River Trail Run

Will I finish last at the San Lorenzo River Trail Run?

Almost certainly not. Half the 13.1 Miles field finished slower than 3:04:40, and the last recorded finisher came in around 5:18:48, so there is a long tail of runners behind the middle of the pack. Most fields are far slower than people expect.

Is the San Lorenzo River Trail Run a good first 13.1 Miles?

It is a small race (135 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.

How competitive is the San Lorenzo River Trail Run?

The 13.1 Miles winner ran 1:58:41 while the median finisher took 3:04:40. That spread points to a mixed field, with a competitive front and a big recreational middle.
