The Forerunner 101 offers athletes and recreational walkers and runners an entry-level personal training device with GPS. It has the same features as the Forerunner 201, but operates on two AAA batteries. The Forerunner 101 stores lap histories for up to two years to provide an archive of workout performance over time. Users can retrieve lap data for previous workouts by date, week, month, or over a specific time interval. For business travelers who want to train on the road, the Forerunner 101 also doubles as a navigator. Users can mark their hotel as a specific location, see their current position on the plotter display, and follow an electronic breadcrumb trail back to their starting point.
Working out with the Forerunner 101 means you're never alone in your personal training, because the unit provides a "Virtual Partner™". This unique feature allows you to set your training goal by configuring your Virtual Partner's pace and workout distance. You'll get a graphic perspective of your performance by viewing your pace in relation to your Virtual Partner's pace, so you can always see at a glance if you're keeping up or falling behind.
