Calories burned during golf... does this sound right?

Womona

Hi all,

Yesterday I golfed only 9 holes, took 2.5 hours, and according to this site, I burned 628 calories because I weigh 128.8. I do push my golf cart, but that seems like a lot to me. Of course my HRT is out of battery so I couldn't track it myself.

Just to compare, I burn 520 cals doing Bikram yoga for 1.5 hours, which is very strenuous. I once burned 800 doing a sprint distance triathlon (when I was 10 pounds heavier).

What gives? I'd LOVE it if I really did burn 628 cals, but sadly, I think it overestimated. thoughts?
