Started the week v pleased with new running toy as was showing good resting heart rate ( tho Bazza pointed out was only part of the story). Yesterday did Stepping Stones run. Looked at data afterwards and found had been running in peak zone the whole time. Much googling later am none the wiser as to whether this is a problem or not. Some articles seemed to suggest that is not worth bothering with HR monitoring at all unless there is a medical issue, but am not quite comfy with that. Have also monitored my dog walks where I do just over 5K an hour and don't get out of fat burning zone. I can't see me extending that much, what with all the sniffing and meeting and greeting. But I do know that I can walk much faster on a treadmill, so am thinking one possible solution is to do fast treadmill walking on non run days to build up in the cardio zone. Any ideas, folks?
