The brits indoor is usually around the beginning of september, There is the scottish triple crown indoor again around september, the dryslope triple crown is in aberdeen on saturday the first of december, They have the third of the triple crowns either at Lecht or Cairngorm in March. There is the Air Attack competiton at snowtrax usually in october. Go big or go home at bearsden is usually in July. The aberdeen one was the weekend before last. Most of the scottish ski hills try to do something but the notice on them is generally short due to the snow conditions. There have also also a bunch of indoor comps/rail jams done by Jibworx that pop u every now and then so there are plenty of opportunities to compete outside of the university scene. I'm sure there are other's i've missed.
