=Predicted Race Times=
The following tables give predictions of race performance at various distances. The prediction uses [[VO2max|V̇O<sub>2</sub>max]] calculations up to marathon distance, then David F. Cameron's Model for longer distances. However, predicting race performance for [[A brief guide to ultramarathon distances| ultramarathon distances]] does not have much value as factors other than aerobic fitness are significant. Even small [[Fixing problems in Ultramarathons| issues in ultramarathons]] can have a dramatic impact on your finish time.

=Jack Daniel's Training Paces=
These training paces are used in [[Jack Daniels Running Formula]]. Note that Jack Daniels does not give a pace for 800 meter Aerobic Intervals, so these are calculated from interpolating from other times.
Sometimes it is useful to know what pace corresponds to a given percentage of VO2max, so the table below provides some estimates.

=Weight Adjusted Race Times=
Adjustments based on changing body weight assume that the change occurs only from body fat, which may not be the case. See [[Weight Loss and Performance]] for more details. (Included are critical power estimates, but these should be taking as only a rough estimate. CP(m) is for males, CP(f) is for females, rCP is a running power equivalent of the biking critical power, which seems to be about 20% higher for [[Stryd]].)

=Long Run Difficulty=
The table below shows the percentage of [[Glycogen]] used on runs of different length and pace. This is one way of evaluating the relative difficulty of different longer runs. The table makes use of a number of assumptions, as listed below, but I believe this is still a useful way of evaluating training runs.
The table below uses a similar approach, but uses a percentage of the target pace rather than an absolute offset.

The predictions for 40f are the baseline values, with adjustments for higher temperatures. The [[Impact of Heat on Marathon Performance]] is based on research for faster marathon runners. These predictions are most appropriate for someone running a three hour marathon. In addition, these figures are a statistical average, so individual performance can be significantly different.

This table shows how altitude can impact running performance. The same scaling factor is used for all distances and the calculation assumes you are well acclimated to the altitude.
