World number 2 female Belle Brockhoff will be looking to keep up her strong current form, after finishing 6th in the final in Soltitude.
While in the men's field, current Top 10 riders Alex Pullin and Jarryd Hughes will compete on one of the shorter courses designed for the tour calendar, and will also be joined by Cam Bolton and NSWIS riders Matt Thomas, Josh Miller and Adam Dickson.
Bulgaria will pose a different test for the athletes than what they have faced so far this season, with a more technical start section which is placed on a steep face.
From there, riders will head into the main features which consist of a step down, triple, table top and final jumps varying in size from 16 to 22 metres.
Speed will be key to success in the shorter form of the track, with qualification starting tomorrow night (AEDT) at 7:45pm for the men and 10:30pm for the women, with live scoring found on the FIS website.
