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 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 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.
