San Juan Trail in South Orange County, CA. My frst "real" ride after being off the bike for 6 months. tougher than I remember, but worth every ounce of sweat. I'm embarrased to say, but I think it was 2 hours to the top (6 1/4 miles up and 2,300 feet of singe track climbing). Of course the 6 1/4 miles and 2,300 feet of descending was amazing.
