Run with the Banana Slugs!

Join us on June 2, 2018 for a beautiful (and challenging) 5k, 10k or half marathon trail run in Beautiful Saratoga!

Trailquake is part of the Brazen Ultra Half Series. All half marathon runners are invited to participate.

The series consists of our toughest half marathons. Most measure at least a little (and sometimes more than just a little) longer than 13.1 miles. What really makes them "ultra", however is the serious ascents and descents and variety of tough trails you have to run to finish them. While flat half marathons are always a challenge, these "ultra-half-marathons" take it to another level!
