A couple of weeks ago I was watching an even and they were tracking Brant Snedeker's paces, distance and calories burned. I believe it was somewhere through 13-14 he had walked a little over six miles and burned about 2200 calories. I'm sure they were doing that with everyone on the leader board. But I found this interesting. I didn't catch the final calorie numbers but it had to be somewhere around 2800k by the time it was over.
