Garmin 210 - trouble keeping track on the track

A shot of the track from this morning
Today's workout (track): 8 x 400's plus 3 mile run

Since I'm racing again next Sunday, I wanted to get in a little speed work before I taper my training next week. This morning I headed over to the local high school track to run some intervals. There were a handful of runners and walkers already on the track when I arrived but the lanes were fairly clear. I brought a stopwatch as well as my Garmin and I ended up using the FR 210 to record my runs and used the stopwatch to time my rest periods between intervals.

I didn't run the intervals hard. My goal was to do mile-equivalents a little faster than my 5K race PR and I managed to average 8:06 across eight quarter miles. I hoped that would recruit enough fast twitch fibers to give me some speed when I ran the following three miles (5K actually) and it did. I averaged 8:45 for that run.

A clear margin of error
The Garmin did not do a good job capturing my route. The picture above is a grab from Google Earth using the imported KMZ file. I stayed primarily in a middle lane but the GPS interpreted that much differently. Even though the 210 is always a little off I still like it a lot. It's great to be able to run without swapping the foot pod every time I change shoes. Especially in the case of the Hattori's that don't even have a place to attach a foot pod.

I'm really happy with today's workout. While I'm still not speedy, I've proven to myself that I can run sub-9:00 paces when I need to. The Hattori's were interesting to use on the track and they responded well when I took off in a sprint to begin each interval. I haven't decided what I'll do for tomorrow's Memorial Day workout but I am hoping to fold in a bike ride or two before I return to the office.
