Hollister, CA
Entry is $30 now and rises to $35 after Aug 1, 2026, so registering before then saves $5.
The course runs through a quarry that is still actively processing sand and gravel, which makes it unlike most races anywhere. You pass heavy equipment, move along a riverbank, and cross between terrain that feels industrial one moment and open and natural the next. That combination is not something most race routes offer.
Parking is free at the quarry site, and the start area is on Airline Highway if you are mapping the drive. The race benefits the local YMCA.

Going by the 2025 results, this is a small, friendly field, and the spread of finish times is wide, so this is a mostly recreational race rather than one for club runners.

The Graniterock River Run has been held every year since at least 2025. That is as far back as RunSignup's records for this race go, so it may well be older.

Almost certainly not. Half the race field finished slower than 37:46, and the last recorded finisher came in around 1:11:01, 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 (176 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 race, that spread matters more than the winner's time.
The race winner ran 19:02 while the median finisher took 37:46. That spread points to a broad, mostly recreational field rather than a race dominated by club runners.
