​​5k course:

Start at Rancho Simi Park and Erringer. Head east on the Arroyo Bike path up to approx a quarter mile past sycamore, to  the turn around point and head on back the way you came.  We will have a turn around sign at the 5k so please keep an eye out for it. 

​In order to ensure a smooth and consistent run, this race has implemented wave starts.

What is a wave start and how does it work?

Wave starts are designed to reduce race start congestion and improve your race day running experience.  In a wave start, runners start in groups at 2 minute intervals. This way you can run with others who are similar in speed.   A wave start will allow you plenty of space along the course, at the aid stations and at the finish line, without affecting your chip time or the time you have to complete the race.  On race day you will line up under / behind the banner that best fits your estimated running pace per mile, see chart below.

Half Marathon: Start time 7:00 am
Start at Rancho Simi Park and Erringer. Head east on the Arroyo Bike path up to approx Angus Ave. The bike path will take a left turn towards L.A.
