April 8th-May 27th

If you are looking to learn how to run on a variety of trails, want to meet new trail running friends, and prepare for the Nisene Marks Half Marathon, then check out our Trail Mix 4.0 Group Trail Running Program. Over the course of  8 weeks, we will have 8 supported, coached trail runs increasing in distance and difficulty. , Our coaches and trail support team will help you safely train for trails and the culminating event of the Nisene Marks Half Marathon utilizing mostly the Nisene Marks Forest Park trails. We require that you have at least some experience on the trails before joining this group. Due to time on the trails and safety when groups get too spread out, we are not able to accommodate walkers on the trails in this group. Please NOTE: Group C will be training by time rather than distance. See below.
