There's really no telling, as it depends hugely on the diffculty of the ride.
On a fairly technical singletrack I'd get it done in about one hour, probably using about 800-900 calories. On an easier ride, I'd get it done in maybe 30 minutes for 300-400 calories. A person that's smaller than average would use slightly less calories and a bigger guy would use more.
