I am a big follower of stats/trends and the bare facts are that no winner aged younger than 8 has won the national for 68 years and only 1 from the 25 6 & 7 year olds to run in the race since 1992 have even completed the course.
The other key stat/trend with regard to Turko is that there has been no french-bred winner since 1909.
That said the stats/trends said 5 year old’s don’t win Champion Hurdles & Chase’s and we all know what happened at Cheltenham this year!!!
