Can my HRM be right?

Options
I used a heart rate monitor for the first time today during my 2:20:00 workout (2:10:00 run and 10 minutes walking for warm up/cool down).

I also use runkeeper with GPS to track my pace and distance. Runkeeper said I burned 2,157 during the run portion, but Garmin, based on the HRM, said I burned 3,194! That is a huge discrepancy! Can the HRM be right?

I weighed 280 this morning, and ran 10.07 miles, plus did another half mile or so of walking during the warm up and cool down.
