How precise does your answer need to be? This can vary with the
person's metabolism, weight and other factors.

As has been noted, weight makes a big difference in the energy
consumed.  An exercise site called Fitlinxx, which requires
registration, has a variety of calculations for various activities:

Fitlinxx varies the calculation by weight; distance; time; and
intensity.  At a medium intensity (5/10), here are the results for
various weights:

Weight: 110 lbs, 236 calories
Weight: 120 lbs, 257 calories
Weight: 130 lbs, 279 calories
Weight: 140 lbs, 300 calories
