If anyone wanted proof of how advertising and endorsement work, here it is. Since Garmin sent me my new Forerunner 405CX running watch at the weekend, I must have had about ten people ask me about the difference between it and the previous model. Perhaps I should have asked them to send me the level up, the 310XT which allows you to do triathlons as you can include swimming as a sports option!
Anyway, today I decided to once again compare the two on a run. My idea was to run a half mile warm up, followed by half mile splits between going all out and then slowing down for half a mile. Of course, with only three miles to play with today, I did:
half mile w/u
half mile fast
half mile recovery at regular pace
half mile fast
half mile recovery at regular pace
but then had another half mile to play with, so I ran 2/5 of a mile fast and then 3/5 of a mile cool down.
Once again, the 405 showed a much larger calorie consumption than the 405CX, which was surprising. As the latter takes heart rate into account, I thought that by raising it for sustained periods of the run that the 405CX might have caught up.
It was only post run that I realised I had different personal values stored in each watch. The 405 still had details from when I first started when I was a little heavier and my resting heart rate was higher. I’ve now put this right and will re-test again tomorrow.
Miles today: 3
Target: 1059
Miles to date: 1,475.28
