HORSES and riders will be put to the test over a demanding course when the Tasmanian Showjumping Championships are held at Stanley tomorrow and Saturday. The titles will be held at the Stanley Showgrounds on a course constructed by well-known course builder Michael Hease, of South Australia, which will include between 12 and 15 obstacles. Friday's program, starting at noon, will consist of a number of non-title warm-up events, with the championships getting underway in earnest from 8.30am on Saturday, as part of the Circular Head Agricultural Show. The titles have attracted almost 70 entries from all over the state and will be conducted in preliminary, C and D grade, under 21, and open championship categories, as well as a speed championship. Defending open champion Kate Hepp, of Hobart, is competing on the mainland and has not entered, with promising Hobart teenager Lucy Watson likely to start favourite in her absence. Watson, 17, was runner-up last year and has been in good form this season, and will ride the well- performed Aquila Starline this weekend. Another Southern rider with claims on the title is Amity Williams, on Ellesmere Derylin, who has also been performing well in recent interstate company. Latrobe rider Wendy Hall will also rate a chance on Rocka, while Cathy Oliver, from Upper Castra, could surprise a few on Kosta Boy.
