TIGER Roll (Gordon Elliott IRE, 11st 1lb) shot to the head of the market for the Randox Health Grand National with Betway when recording a stunning four-length victory in the Grade 2 Boyne Hurdle at Navan yesterday.

The 2018 Randox Health Grand National hero is now 12/1 clear favourite with Betway. If successful at Aintree on April 6th, the nine-year-old would become the first horse to record back-to-back victories since the great Red Rum in 1973 and 1974.

Trainer Gordon Elliott confirmed after yesterday's success that Tiger Roll will now head to the Glenfarclas Cross Country Chase at Cheltenham on March 13 ahead of the Randox Health Grand National.

Weights for the 2018 Randox Health Grand National were revealed on February 12 at the iconic Cunard Building in the heart of Liverpool. Bristol De Mai (Nigel Twiston-Davies, 33/1) heads the weights on 11st 10lb. The eight-year-old is a four-time G1 winner, including the last two renewals of the Grade 1 Betfair Chase at Haydock Park.

The 20/1 joint-second favourites with Betway are this season's Welsh Grand National victor Elegant Escape (Colin Tizzard, 11st 4lb) and Mall Dini (Pat Kelly IRE, 10st 4lb), who shaped well when sixth in the valuable Thyestes Handicap Chase at Gowran Park on January 24th.

With a prize fund of £1 million, the world's greatest chase is the most valuable Jump race globally and takes place over four miles, two furlongs and 74 yards and 30 fences at Aintree at 5.15pm on Saturday, April 6th, day three of the Randox Health Grand National Festival.

This year sees the 172nd running of the great Aintree chase.
