Why is there always a non runner in 16 runner handicap but none in 40 runner National

Not that strange surely?! Most famous race in the world with unbelievably good prize money. Very few NR's in the handicaps at Cheltenham for similar reasons.

And 139 last year 145 this .....what next year , best to take your chances now .

a) there was a non runner last year - Carlito Brigante pulled out after the deadline for the reserves to take up the missing place and caused controversy whereby the deadline for the reserves to take up a place was extended from 9.0am to 1.0pm the day before the race.

b) As above, there are four reserves in an attempt to ensure a full field - so only realistic likelihood of a withdrawal now is if a horse is sick or lame on the day of the race.

Over the past ten years, anything up to 5 horses have scratched after the confirmation stage. With very few exceptions, they have been surprises.
