Re: calories burned walking 18 holesFrom the last page of my TPC River Highlands, Cromwell Ct. 2010 spectator handout booklet:
"If a spectator were to follow player's along 18 holes of the Travelers championship, they would walk approximatly 4.5 miles
(9000 steps) and burn approx. 485 calories".
Now since most of us do not hit; Driver, Chip, one putt. and I don't recall the course being all par 3's, I would suggest we multiply that by 2, and we'd be close. And these #'s are for on the cart path, for the spectator.
This would also take into consideration variables like "standing around the tee box" and I would think that dodging other spectators would more than cover the energy used swinging clubs, and of course caring for our own equiptment... which on that day we carried folding chairs, which needed to be manuvered among the masses.
Now, I'm no "Gulf coast Oil Rig leak Engineer" But this is close enought for me.
Hence: less than 1000 calories.
