Learn more about the trail system at Arcadia. The group will rip a trail from the Fox Lake trailhead to Edmond Park beach and back, eight miles in total. They will break at the beach for a swim (in the cooler months you'll dip donuts) and then head back.

Mountain bikes are available but supplies are limited. Be sure to bring a helmet, a water bottle and a sense of adventure.

Also held: Oct. 7 & 28; Nov. 11 & 18.
