Fitness category is defined to approximate quintiles of the overall data. Exact quintiles are not achievable because of breaks occurring at partial lap numbers and ties in the number of laps. The levels or approximate quintiles were determined overall and by gender. The levels (and the number of observations) are defined as follows: males: level 1 = 0–11 laps (n = 560), level 2 = 12–16 laps (n = 438), level 3 = 17–24 laps (n = 433), level 4 = 25–35 laps (n = 458), and level 5 = 36–89 laps (n = 452); females: level 1 = 0–11 laps (n = 631), level 2 = 12–15 laps (n = 554), level 3 = 16–18 laps (n = 385), level 4 = 19–26 laps (n = 573), and level 5 = 27–74 laps (n = 471).
