Bernalillo to the Gilman Tunnels (photo above from a few years ago), and back again. This was one of the most scenic rides I've ever done. It was tough work climbing the hills up to the tunnels, and I was worried about being able to finish the ride after being so burnt at the turn-around point. The ride back turned out to be pure fun in the sun... but less scenic as it flew by so quickly :)
Next week, it'll be 85 miles. Then finally, the 100 miles of the Santa Fe Century. I'm ready to be done with it. These long rides are getting tough. After this, I may stick with 50-mile rides for fun.
