First workout with new toy
I bought a fancy Garmin 305 heart rate monitor that also has built-in GPS so that it can track my location, elevation, pace, etc. I wasn't going to run today, but with a new toy in hand, I figured a quick lap around Green Lake wouldn't kill me.

Here are my workout results.

See if you can figure out where I stopped for water.

If you change the graph options to display speed vs. heart rate, you can see that there are considerable variances in my speed which I attribute more to the device than my own herky-jerky rookie running style. More interesting to me is how my heart rate stays relatively constant but rises and drops very quickly when I slow down or stop.

It is awfully nice (and motivating) to be able to look down at my wrist and instantly see how far I've gone and how fast I'm going. My worries about maintaining a 12-minute mile just evaporated...I can even set an alarm on the 305 to ring if I drop below a 12-minute mile pace. I wish I'd bought this thing a long time ago.
