Constitution Hill and Shishkin make it a first day Hen party for owner Nicky at Aintree Grand National

CONSTITUTION HILL and Shishkin made sure Aintree’s opening day turned into an almighty Hen party.

Nicky Henderson landed the big two races in the space of 35 magical minutes and puffed out his cheeks to admit:

“It’s been a good day.”

First up was Shishkin, who blew away any doubts about staying three miles, by scorching clear from Ahoy Senor to lift the Aintree Bowl.

Henderson reckons he could have the perfect candidate for Kempton’s King George on Boxing Day…

And potentially a Cheltenham Gold Cup winner of the future.

Then came Constitution Hill, the superstar who took his record to a perfect seven from seven in the Aintree Hurdle without breaking a sweat.

Owner Michael Buckley and Henderson will now discuss whether to send their brilliant hurdler over fences.

The three-length stroll over Sharjah was so comfortable even the notoriously nervy trainer could enjoy it.

He said: “It couldn’t have been more straightforward, he’s had a nice day out.

“Now we’ve got a long summer to enjoy this and talk about what’s next.”

Coral go 25-1 Constitution Hill for next year’s Cheltenham Gold Cup.
