CORK'S Billy Twomey and Tipperary's Denis Lynch will continue Ireland's battle for two Olympic places in show jumping when they compete at the World Cup show in Zurich, Switzerland, this weekend.

Following a fourth place finish in the World Cup class at Leipzig in Germany last Sunday, 34 year-old Twomey now heads the unofficial Olympic qualification table, but Lynch is close behind in second. Points gained at Zurich will enable the duo to fight off the challenge posed by riders from rival countries who are also attempting to secure the three available individual slots for London this year, which will be allocated on March 1st.
