5K Run:
This program automatically sets a 5k (5 kilometer) distance as your goal. The track display will
show one loop that is the equivalent of 5 kilometers and the Distance window will also show 5k to
start. When the program begins the Distance will count down; once it reaches zero the program
ends.
*Please note that the Speed readout is in MPH if the console is not set to Metric.
Fitness Test:
The fitness test is based on the Gerkin protocol, also known as the fireman s protocol, and is a
submax Vo2 (volume of oxygen) test. The test will increase speed and elevation alternately until
you reach 85% of your Max heart rate. The time it takes for you to reach 85% determines the test
score as shown in the chart below.
