The lagoon may or may not be home to a mysterious monster and lost treasure of pirates, but it is definitely home of riches in the form of trails to run!

Bursting into spring, Brazen is heading to a park which encompasses a lagoon we're not entirely sure is uninhabited. All runners will be treated to some sweet single track in the surrounding park while half marathoners make their way up to the top of the mountain for a possible sighting of the lagoon critter.

Start times will be: 8:00 am for the Half Marathon, 8:20 am for the 10K and 8:40 am for the 5K.

All races will be professionally timed.

All runners will receive custom finisher medals and custom shirts (cotton and tech shirts available). More info on shirts/awards page.

Age group awards will be awarded to the top 3 finishers in 5 year categories (less for the younger ages).

Hikers/walkers are welcome.

A 7:30 am start start will be available for hikers. Hikers must carry water and be capable of following the course map on their own. Course monitors and aid stations may not yet be open for the first part of the course. Hikers are not eligible for overall or age group awards, but do receive official finish times, finisher medals, shirts, etc., exactly the same as all other runners.
