Heart to heart

I'm trying to use my Garmalade's heart rate monitor. So, I calculated my maximum heart rate (around 189 beats per minute) based on a formula from Runners World. And then I determined my endurance heart rate zone (123-142).

And, on today's run, I averaged 139 bpm. Pretty neat, eh?!?! It was cool to see how my heart rate went up *a lot* on big ole hills AND how my rate went way down while running downhills or jogging. But there are still things to figure out, since the monitor's band is not that comfortable (fits by the bottom band of my sports bra) and I'm not completely sure what my precise maximum rate is....
