Last Night’s Tempo Run

This was my first tempo run this season also the first with my Garmin 305. I was hoping to be able to run as fast as I had last season but alas I was much slower than before and there were some strange anomalies.

The most interesting one was my heart rate. I’ve used 165 as my Max Heart Rate for some time. This was measured for me at my health club and I have tested it numerous times in the past. But for the first 10 minutes of this run, my heart rate was up to 187. At least that is what motionbased.com indicates. Can your Max Heart Rate ever increase like this? It would be neat if it were true. But everything I have read and heard is that the heart rate decreases with age and never goes up. The literature indicates that for extremely active individuals the HR does not decrease with age. and I have noticed it on some of my friends. So what is going on?

The URL for the activity is:
Oct 26 Interval Run

I am having trouble figuring out how to analyze the data stored on MB. Here is the workout I did:

1. Go until I press lap
2. Go until HR above 135.
3. Go for 2 miles keeping HR between 135 and 155
4. Go until HR goes below 105
5. Go 1 mile

First off I had trouble getting my HR above 135. Finally I cheated and pressed the lap button which put me in the next lap. Then I ran a rather eventful 1.5 miles and stopped. I stopped once toward the end to talk to my wife. I guess I must have hit the stop button because the last half mile are not recorded.

How do I get my pace from the data? I can calculate it but you would think that would be some of the data that would be presented in all the graphs and tables they show. That is important information so that I can sharpen my running skills.

While we were running some people were on the street watching the sky. I originally thought they were watching the moon which was really bright and large. It was at perigee last night. But when I got up to them and ask they pointed out the space station and the shuttle going over head.
