In all of our rankings and articles for the winter season, we will distinguish between outdoor or "All-Comers" performances and true indoor performances. This is because the size of the track has a definite effect on the performances: smaller indoor tracks with tighter curves sap more energy and speed from the runners, while full-size outdoor tracks with larger curves make it easier to maintain speed. Indoor conditions and equipment can also impact field event performances (sometimes positively, sometimes negatively). We will always use the term WINTER in article titles to refer to outdoor performances (which can also be found using the term "polar bear" in our rankings. We will always use the term INDOOR in article titles to refer only to true indoor track performances. Whenever we have both indoor and outdoor performances together, we will always use the heading WINTER SEASON.
