Burning Lots of Calories

I think I'm going to either lose a lot of weight this summer or eat a lot of food-- at least based on the calories I burn on some of these rides. When I'm riding in the hills, I seem to be burning around 1,000 calories per hour. On Saturday, I did the ride from Redwood Valley to Orr Springs and back. The ride was 37 miles long and had 5,040 feet of climb. According to my bike computer, I burned 2,966 calories in 2 hours and 59 minutes. This summer, we plan to average 83 miles a day. If we average 15 mph, that should take about 5 1/2 hours per day (or about 5,500 calories worth!).
