Day 16: 6mi, 48:55

I did an easy 6 miles outside this morning. A beautiful, sunny day, but only 20 degrees F, with a brisk wind. Running into the wind for the first three miles kept my pace down, although the additional effort helped keep me warm. I run in the cold a lot, but this is the first time I remember my feet feeling cold. I kept a steady pace throughout, basically 8 mniute miles. Ending HR at t+1 was 120bpm, and at t+5 was 100.

Gmap One issue with running outside is trying to figure out how far I've actually run. I used to estimate my pace and back out the distance from the total time, but this is pretty rough, especially for longer distances. In marathon training, makes a big difference if I estimate I ran 21 miles but it was really only 19. Maybe that's why I always run too fast in the first half! But now there is an online solution to the problem: Gmap, a web-based pedometer that uses Google's mapping technology. You can plug in any route on here, and it will give you an accurate measure of the route's distance. My run today is here:

Gmap says it was 5.9669 miles. I'll go out and do the other 0.0331 miles later.
