A fellow mountain biker Facebook friend got a heads up about this event along with a request to share it with the local mountain bike community, so what better place than imtbtrails to spread the word? For anyone planning to ride in the Santa Anas November 18th or 19th, prepare to be humbled by about 105 runners who are participating in the Chimera 100 running race! There are 100K and 100 Mile options ... so something for everyone. After stumbling across an off road marathon when we did our Holy Jim/Trabuco loop, I appreciate the organizer reaching out to other trail users to give us a heads-up, and also thought it would a good idea for us to post up any upcoming events on our local trails so that people can either adjust their plans or be prepared to defer to them on the trail and cheer them on. It can be a bummer to arrive to a trailhead only to find closed trails, or feel like you're going to be in the way of something special that people have been training for. Would it make sense to add events like this to the calendar so there's one place to check for any events that we might want to know about before we head out to the trails (even if they're not events we're participating in)? So you know where they'll be starting at 6AM on 11/18 and continuing into 11/19, here's the basic route: They'll be starting at Blue Jay at 6AM on 11/18, then: Down the San Juan trail and back up, down Chiquita to the candy store and back up to Blue Jay up Main Divide to Trabuco down Trabuco and up Holy Jim up Main Divide over Santiago Peak to 4 Corners and back (with a detour to the top of Modjeska Peak) Main Divide to Indian Truck Trail down Indian Truck Trail to Corona and back up Main Divide back to Blue Jay 100 Miles and 22,000' of climbing ... @mtnbikej, I think they just planned the route for your next death march for you I checked out their website out of curiosity and disbelief. There is a 35 hour time limit, and the top finisher last year did it in 23 hours! http://www.oldgoatraces.com/races/chimera-100/ If you ride out there that weekend be sure to cheer them on and give them all the trail courtesy they deserve!
