Business School is situated at Wheatley, which is a 15 minute bus ride away from the the main campus.
Sports facilities at Wheatlye are limited to floodlit pitches for basketball, tennis, football, netball etc. At gispy lane however, there are floodlit pitches and the main sports centre, which has a gym, squash courts, badminton courts... loads things to do... plus there's a bar there as well. I have absolutely no clue about a boxing club tbh. If there isn't one at Brookes, I'm sure there'd be one nearby.
