A mountain bike ride, of course. Chuck and I joined Ken Mathis's event to climb the toll road. Terri Boykins joined Chuck and me to descend the Mt Lowe RR Trail to return to the cars (and did very well indeed on her hard tail mountain bike). There were some strong, gusty winds on the descent when we reached the south side of the ridge line, but nothing too scary. The views of PV, the ocean and Catalina were great. It was a great pleasure to see Ken, even though we did not get a chance to visit. Chuck was dropping me most of the day on the climb. Grrr. LOL Metrics: The max FiETS score I can select is 13.11, but the true climb from the fork just past the bridge to the gate at the top is 8.6 miles with 4318' of elevation gain and an average grade of 10%; FIETS score = 13.07 RWGPS reports the max grade is 17.4%, but that is the little, paved kicker just before the gate on your way back to the car. Otherwise, the max. is 16.4%. I mentioned to Ken that I thought it was a harder climb going up the Mt. Lowe RR Trail, but the metrics do not seem to bear that out.
