2018 Half Marathon/Relay Course

Updated 5/17/2018

We will not know until September if the rockslide on North side of the Lake Natoma trail will be cleared, so here you will find the Half Marathon/Relay course as it was modified for last year's event. Stay tuned for any changes.

Below is the 2018 Half Marathon/Relay course map as it was run in 2017.

Confirmation of this course will come in September. If the rockslide on the North side of Lake Natoma is cleared in time, the 2013-2016 loop course around Lake Natoma will be used.
