My new Garmin Forerunner 305 comes with some rudimentary graphing and mapping software. Here’s a few graphs from today’s easy run (45:34, 4.84 mi, 9:24/mi). Each graph links to a larger view.
First, heart rate and pace. I got faster as I ran, with the first mile at 9:47 and the last 9:05. Unfortunately, the graph is pretty jumpy, there’s no “smoothing” option, and the scale is hard to control.
What of that big decline in heart rate between 25:00 and 27:00? This graph of heart rate and elevation explains it–a long downhill:
The data is stored as XML, so I’m sure it’s possible to extract it and make better graphs. We’ll see. For now, these are still useful. And I’m very glad to have a convenient way to monitor the intensity of my workouts. Like a lot of runners, I have a tendency to over-train.
