Entertainment in the nature of racing or competition in sports; We use the term "YCross" (or "Ycross", "YCROSS") to describe a format of race course design where racers come down a course in slalom on separate tracks at the top, converge together in middle onto a single track, and then proceed together on that single track towards the finish; The shape of the course therefore resembles a "Y"; We have used it in mountain bike racing, snowboard racing, and ski racing, but potentially will adapt it to other forms of sports racing
