    With the exception of the first quarter mile, this is a very flat, very fast course, which is considered a SPRINT COURSE by most, and if you are a runner looking for a new PR, then look no further. Both courses feature spectacular, wide open lagoon views and a DOWN HILL finish.

Trail Running is not just for adults...

The ERS is excited to offer our very popular "Kid's Dash". These races are geared towards kids 10 years and younger, and will measure about 1/4 mile in distance.

What is Cupless Racing?

The ERS will provide the aid stations on course with water and electrolytes. The runner will be responsible for providing their own hydration vest, bottle, or reusable cup to use at those aid stations. Runners are allowed to fill up as much as needed. 



If you are a local (or national) company looking to be a part of a fun, family-friendly finish line festival at some of the best trail races in Colorado and San Diego, then the ERS has a spot for you.
