By the time I received my MS in Nov 2012, Cottonwood had made a run up Trail Ridge Road, and the pass was already closed for winter: With a high of 98° F forecast for Boulder yesterday, it seemed like the time had finally come for us to make our own belated run up the Ridge. Up top it was a balmy 68° with light puffy clouds and light winds (somewhat uncommon in my experience--usually by the time I make it to the top it's raining and cold). My energy useage graph was as rugged as the peaks off on either side, but my overall Wh/mi was only 268 (I'm almost never below 300 down on the flatlands, but there I'm usually in heavy traffic on the freeways.) I gained 9 miles of rated range on the way back down (probably closer to 11 since I didn't start to uptick until I was halfway back up to Allenspark). I started with a 100% charge, and ended up just under 50%. Of course, we ran the AC instead of heat, and speeds were quite slow going up and down (although there were countless stops along the way to hike and take photographs).
