Henneke horse body condition scoring system Cup (a 160-km / 100-mile 24-hour race held each August near Truckee, California) found both for 1995 and 1996 (study 1) and for 1998 (study 2), that significantly more horses finished the race when they had a higher (vs. lower) body condition score: Horses competing in 1995 and 1996 had body condition scores ranging from 1.5 to 5.5 (1998: 2.5 to 5.5); no horses with a score of ≤ 2.5 (1998: scores ≤ 3) finished the respective race, and all horses with a score of 5.5 (same in 1998) finished the respective race. In both studies, no significant relationship was
