Ride report

After lunch I started my ride and rode 21.52 miles in one hour 44 minutes and 15 seconds. I burnt 1042 calories on a ride which was averaging 12.41 mph with a top speed of 20.40 mph. The weather was a hot 91 degrees with a wind out of the NE at 6-12 mph. I am trying to complete 20 miles each day to try to shed some weight. If I could loose a 1/2 pound per day I would be happy. I wonder if there is a calculator to figure how many calories needs to be burned to drop a pound.
