Interpreting the results
If you are new to running or just haven't been out for a while, your
running performance may be quite low at first. But as your physical
fitness and running technique improve, you should see a
corresponding increase in running performance.
Over a 4-20 week period, you may see an increase in running
performance level up to 20%. If your running performance level is
already good, it is difficult to improve further. In this situation,
running performance level is better used as an endurance indicator.
Following the real-time difference indicator provides detailed,
granular information on daily performance and fatigue during the
run. Endurance runners can use this information to learn how much
fatigue seems manageable during long intensive runs. During races,
this information helps you pace yourself properly.
Illustrated below are three samples running performance levels
during runs. In the first graph (1), performance is good. In the
second (2), performance is bad and may indicate over training,
illness, or just generally bad conditions. In the third graph (3), you
see a typical long distance run where performance level drops
steadily later in the run, indicate onset of fatigue.
