|JAS is British Eventing's form of indoor eventing|
Jumping and Style (JAS) is run in the winter months and combines all aspects of eventing in one round of jumping. Riders are judged on style, with low scores indicating the best style, as they complete a round of show jumping followed by a round of timed cross country jumps. Penalties are awarded knock downs and refusals in both phases and for exceeding the time in the cross country phase. The lowest score of STYLE+SJ FAULTS + XC FAULTS + XC TIME FAULTS wins!
