We tackled the shoreline at Land's End park in the rain, sprinted around the Kezar Stadium track and up its stadium steps (multiple times), powered up
Filbert Street (the steepest in all of San Francisco), and down the zigzagged Lombard Street, pushed the pace on a self - powering treadmill during a HIIT workout, strode across the Golden Gate Bridge in Karl the Fog (yep, they have a
name for their fog) and, finally, braved the Bernal Heights hill, which was rewarded with a breathtaking view of the San Francisco skyline.
