Hi,

I'm about to get the bikes out of the garage and basement and start putting some miles on this season. I also have a goal to shed excess weight this summer, so along with that I've been exploring apps to run on my Blackberry Curve.

At lunch today I took a break from work and went for a walk, out the building, through some woods, along a powerline road adjacent to a golf course, rambling over brush and following deer trails, then back to the building on a fitness trail. Total distance was about 2.2 miles, total time was about an hour (fished a couple of golf balls out of a creek so lost a little time there j) ) .

I was using two apps on the phone: Endomondo and iMapMyRide, both in walking mode accessing the phone's GPS. I was also using a Polar F6 HRM.
Here are the results:
Endomondo says 310kcal and 2.11 miles.
IMapMyRide says 224kcal and 2.29 miles.
Polar HRM says 478kcal, 1:05:56 elapsed time, 125 max heart rate, 105 avg heart rate, and some other stuff I haven't figured out how to retrieve yet.

I'm in my mid-50's, weigh about 250Lbs, stand about 5'11", and I think some or all of that is programmed into the HRM and one or both of the phone apps.

I might just use the HRM while on the bike, but am thinking one of the phone apps might be nice as well since they have the route/map record in case I want to share a route with someone.

So, are any of these halfway accurate, or should I just average them?

Thanks in advance for your opinions.
