Forerunner 301

From MB Wiki

The Forerunner 301 (http://www.garmin.com/products/forerunner301/) is a Garmin fitness GPS device continuously monitors your heart rate, speed, distance, pace and calories burned so you can train smarter, more effectively. The Forerunner 301 combines the popular features of the Forerunner 201 with a heart rate monitor and Garmin Training Center software to create a highly integrated personal training system.

Guidence

The Forerunner 301 has limited guidence capabilities, and accepts routes with less than 100 waypoints. In most cases, this is less than desirable for guidence. It does NOT have course or track guidence capibilites.

Troubleshooting

Scenario & Question:

A friend and I rode a bike tour that was 205 miles. Both of our Garmins didn't pick up the first 70 miles of the ride. Very weird that it didn't register. When I left the parking lot, it was recording. In fact, it says 205 miles on the device. The Forerunner 201/301 was right on, but once downloaded to MotionBased, it missed the first 70+ miles.

Any idea what is going on???

Answer:

The easiest way to say this is that it may be time to upgrade your device. All devices have a maximum number of trackpoints in the active memory. The FR201 has 3,000, the FR301 has 5,000 and the Forerunner 205/305 and the Edge series have roughly 13,000. Once you reach the max trackpoint, the device will simply start recording over the beginning of the track log; it eats away at itself. In this FR201 example, the ride was too long for the FR201 active memory storage.
