The runs are 5am-7am, 8am-9.45am, 10-15am-midday, 1pm-2.45pm and 3.15pm-5pm with up-to-date tallies posted at the end of each break.
The seven judges – one watching from his home in Wales – will be keeping a close eye on quality and the wellbeing of the young sheep, with authority to reject any lambs not shorn up to standard and stop any shearer not consistently meeting the benchmark.
With the station still in the red zone of the Covid-19 traffic-light protection framework, there will be no public admission, but live-streaming is available on the attempt's Facebook page.
