2 Custom User-defined Programs
These programs enable you to set up, store into memory and then work out in 2
different course profiles that you customize.
Time Trial
This program enables you to work out against a “pacer” to determine how long
it takes you to cover a preset distance. You preset the speed of the “pacer” as
the baseline of your workout and race to the end of the preset distance. At the
end of the Time Trial, the computer displays the watts, distance, speed, etc.
that you have achieved.
Fitness Test
The Fitness Test is one of the best ways to measure improvements in your physi-
cal fitness level. The test measures your fitness by comparing your power output
(in Watts) to your Heart Rate. In general, as you become “more fit,” you will pro-
duce more power (Watts) at a given Heart Rate.
Here is how the test measures your power and heart rate. As the test starts,
the power (watts) slowly increases. This means that you will work harder, and
as a result, your heart rate increases. The watts continue to increase automati-
cally until your heart rate reaches the “Test Zone.” This zone is individually cal-
culated for each user to be near 75% of their estimated maximum heart rate.
(This "Maximum Heart Rate" is computed from the information you input into
the computer when you start the program. These number values are different
for everyone.) When you reach the Test Zone, the bike holds the watts steady
for 3 minutes to allow you to achieve a steady heart rate state. It is important
to concentrate on keeping a steady heart rate during these 3 minutes to ensure
consistent and more accurate readings.
At the end of the three minutes, the computer measures your Heart Rate, and
the power (Watts). These numbers (along with information about your age and
weight) are put into a formula, and produce a “Fitness Score.”
By logging and noticing the change in your own fitness scores, you can see your
progress to increased fitness. The higher your score, the higher your fitness
level. For example, let’s say you have an initial fitness score of 28. Four weeks
later you perform the test again and your score is 35. This means you have
increased your fitness. Your power output has increased and at the same time
your heart rate has decreased. You are producing more power with less effort.
Note: The Fitness Test is an excellent way to measure changes in your own fit-
ness level. It is not designed to compare one person’s score to another person’s
score, because the test's formula only “estimates” your Maximum Heart Rate.
Therefore the numbers are only relevant when compared with your own fitness
scores. (There are no corresponding "absolute" numbers in the owner’s manual
that you can reference to see what your fitness level is.)
