Mr Frisk (c.1979 – September 2000) 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.
After retirement from racing he continued as an eventer, trained by Tracey Bailey.
[citation needed] He was put down in September 2000 after fracturing a hind leg.
