Enter a recent race result. Both models are shown because they disagree, and the gap between them is the honest width of the prediction.

Both models assume you are as well trained for the target distance as for the one you raced. Neither knows how many long runs you have done, so both will flatter a marathon predicted off a 5K. Tap a distance for its splits at the midpoint of the two.
