Garmin Forerunner 301

I have recently bought a Garmin forerunner 301:

This is an excellent training partner that continuously monitors your heart rate, speed, distance, pace and calories burned! I’ll run the Paris marathon next April and I really though that I need such a little cool device to train smarter and more effectively.

The bundled software is poor but I am now using sportTracks. The following is a picture of my today workout:

SportTracks automatically track the distance, time and pace of your workouts. You are even able to visualize your route with google earth. This is cool. Moreover, you can analyze your pace, elevation, or heart-rate performance.
I hope I’ll be ready for April. The only problem is that I’ll not be able to claim that I was badly trained when I’ll have to explain a counter-performance.
