Common Questions About the Pasadena Trail Half & 10k/5k

Will I finish last at the Pasadena Trail Half & 10k/5k?

Almost certainly not. Half the 10K field finished slower than 1:04:37, and the last recorded finisher came in around 2:20:04, so there is a long tail of runners behind the middle of the pack. Most fields are far slower than people expect.

Is the Pasadena Trail Half & 10k/5k a good first 10K?

It is a small race (103 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 10K, that spread matters more than the winner's time.

How competitive is the Pasadena Trail Half & 10k/5k?

The 10K winner ran 44:04 while the median finisher took 1:04:37. That spread points to a relatively quick field, so expect a competitive front end.

Where can I train for the Pasadena Trail Half & 10k/5k?

Join a local run club. Pasadena Pacers, Pasadena Run Club, Run With Us Pasadena and others in Pasadena welcome runners of all paces, and a weekly group run is the most reliable way to hold a training block together.
