Oregon Pace Wizard can be used to compute effort based paces
and pulse rates for training and racing. The Wizard uses your
recent race performances to determine your ability.
If you know your Max and Rest heart rates
the Wizard will use those to determine your target heart rates
for training and racing. If you have measured your average heart rate
in a recent race or on a training run, the Wizard will use that to estimate your Max heart rate. Otherwise Wizard will assume 220-age
for your Max HR and 50 for Rest HR.
