The 12K finishes at the Marathon Finish Village at Highway 1 and Rio Road in Carmel.  


We do not allow the use of iPods, headphones, ear buds or other MP3 or headphone devices in any of our events. We believe using an audio device will compromise your safety and that of others by hindering your ability to hear verbal instructions or commands from race officials including course marshals on bicycles or to hear vehicles in the lane next to you or emergency vehicles on the course. You are sharing a narrow lane with runners of different speeds completing different race distances. In addition, there is live traffic in the land-side lane of Highway 1 during the race. You must be aware of your surroundings at all times

Because the safety of all of our participants and volunteers is our first priority, we ask that you leave your headsets at home and instead let the incredible scenery, music we provide on the course, and your fellow runners serve as your motivation and inspiration.


All participants receive an ASICS technical fabric shirt in gender specific sizing and a unique ceramic finisher medallion.
