Another 4th of July adventure ride. While riding up to the Baldy ski lifts, I started to feel a little dizzy and had a headache, so I backed off and brought my pulse rate down low for the rest of this ride. Beforehand, I had ridden pretty hard up the back side of GMR (from East Fork). I had a late start due to a mechanical and missed visiting the riders on Karen's GMR "Climbfest" event. I decided to stop and have a big lunch at the lodge after descending from the ski lifts to see if I recovered, and decided spontaneously to just keep riding to see how far I got on an idea I had earlier, to try climbing Baldy, Dawson Saddle, Mt. Wislon, Mill Creek Summit and Camp 9 "one day". I had not originally planned to ride at night, so I did not have a battery with me to recharge the Garmin, and I did not have my regular lights, so I just rode home after finishing Mt. Wilson, which was plenty given the late start and no planning. I inadvertently stopped the Garmin's timer at Dawson Saddle, and did not catch the problem until maybe 10 miles later, at Buckhorn (past Krakta Ridge and almost to Mt. Waterman). The missing metrics from another ride are below.
