The Virtual Grand National 2020 (STV, 5pm)

ONE of the knock-on effects of the global coronavirus pandemic has been the postponement of many major sporting events. Although the Cheltenham Festival went ahead at the beginning of March, it had become clear that subsequent horse-racing fixtures would have to be cancelled. One of the meetings put on ice was that of the Grand National. The loss of this year’s race was especially damaging to the sport, as Tiger Roll had been due to attempt the unprecedented feat of a third consecutive success after wins in 2018 and 2019. However, with the race postponed, this year’s virtual running, hosted by Nick Luck, could be the definitive opinion of what would have happened if the 173rd staging of the event had gone ahead. In addition, there is also a chance to see what happened when sophisticated algorithms pitted the legendary three-time winner Red Rum against modern-day great Tiger Roll.
