Yorkshire's biggest jumping day proved the catalyst for changes to be made

It was the Charlie Hall Chase meeting at Wetherby in 2014 that set in motion a small revolution in jump racing.

Race times on the day, including that for the feature event won by Menorah, were surprisingly quick and led to a remeasurement of the course.

That revealed four of the track's 12 distances were incorrect, with the supposedly 3m1f Charlie Hall itself having been staged over a trip 78 yards too short for five years by that point.
