Mr Frisk was a Thoroughbred racehorse, which won the 1990 Grand National. He completed the course in record time of 8 minutes and 47.80 seconds, ridden by Marcus Armytage; this still stands, even though the race has been 342 yd (312.72 m) shorter since 2013. The pair also went on to win the Whitbread Gold Cup three weeks later - the only horse to achieve the double. The second placed horse in the National, Durham Edition, also filled the second place at Sandown.
