Treadmills are known to be inaccurate as far as calories burned goes. If you want a more accurate measure, try wearing a heart rate monitor. Otherwise, I'd probably use the Spark tracker's information. That may just be because I would rather underestimate burned calories than overestimate though.

Why is there such a difference in calories burnt from my treadmill and SparkPeople? Today I walked 50 minutes at 2.5 miles per hour - my treadmill says I burnt 263 calories and when I enter my time in my Fitness Tracker it says I burnt 171.
