Conejo Open Space Challenge

Here’s your chance to explore some of the best trails in the Conejo Open Space that most people are not familiar with! From March 1st through May 31st we are challenging mountain bikers, hikers, trail runners and equestrians of all ages to try out some new trails. See if you can complete all ten trails before your friends do!

The 9th Annual Challenge runs March 1 – May 31, 2020

Here are the trails to explore for this year’s Challenge (you can also download as a flyer):

Hike, run, or ride (bike or horse) each trail from 3/1/20 to 5/31/20. Share your photos via Twitter or Instagram with tag #coschallenge or email them or a link to a GPS track to coschallenge@gmail.com for validation.

Win prizes donated by our awesome sponsors (give them shout-outs with your photos) by completing all 10 trails, which enters you in the raffle. Attend the post-event party (more info to come) to see if you won.

Follow all posted rules, do not hike/run/ride when trails are muddy or closed, and stay safe. This is not a race, so take your time and enjoy the experience.

There is no fee to participate in the Challenge. You can support the Conejo Open Space Conservation Agency (COSCA) by making a tax-deductible donation to the Conejo Open Space Foundation (COSF) at cosf.org/donate. COSCA is the agency entrusted with preserving, protecting, and managing the open space resources in the Conejo Valley, including management and maintenance of the trails in this Challenge.
