Description of the JPL-Nino Canyon 10K Course:

by Sam Dolinar




The JPL-Nino Canyon 10K Course was once an officially measured out-and-back 10K course that started at JPL and continued up Arroyo Seco Canyon past the picnic area at Nino Canyon to a turnaround point 5 kilometers from the start, then returned to the start. The exact route has suffered from several road washouts and bridge outages over the years, and as of now this is no longer a certified 10K course, but it remains approximately 10 kilometers in distance.

Here's a map from the 1980s describing the JPL-Nino Canyon 10K Course.
