The challenging and unique courses will take you out on the Lake Poway Trail through the foothills around the lake near Blue Sky Ecological Reserve. The 5K is designed to let you pick your pace. Enjoy it as an elite trail runner, as a challenging family run or simply a gorgeous morning nature hike. The 10K adds to this course a grueling out-and-back (or up-and-down if we're being honest) into Blue Sky and a quad-burning +10% climb to the Ramona Dam.
