That ride doesn't have 3500 feet of climbing - more like 2800. But it's still one of the tougher 60 milers around. I had a lot of fun and in spite of a couple crappy and speed robbing mechanicals, smoked the course. Finished it in 3h35m including stops. I thought the new pavement in Glen Rose was great, and the enw 'boulder-seal" out of it was pretty bad! But the scenery is always so nice, even after having done the ride several times.
