DO go chasing waterfalls! Join Fitbit Ambassadors Mike Sherbakov and Sheri Matthews for a scenic seven-mile hike. We’ll work our way through the volcanic rock and along an oak-lined stream at Los Penasquitos Canyon Preserve! Your furry four-legged friends are welcome as long as they’re on a leash. Stick around after the workout for a chance to win a Fitbit tracker of your own.
