The winner of the Hennessy Gold Cup at Newbury in November, 2014, Many Clouds was sent off 7/1 second favourite for the Cheltenham Gold Cup the following March, but could manage only sixth, beaten 24½ lengths, behind Coneygree. Consequently, when he lined up at Aintree less than a month later, under the welter burden of 11st 9lb, he was a largely unconsidered 25/1 chance.
However, ridden by regular partner Leighton Aspell, he raced prominently for most of the way and was left in the lead when second favourite Druids Nephew fell at the fence after Valentine's Brook on the second circuit. Thereafter, he made the best of his way home and set off up the run-in with a three-length lead over his nearest pursuer, Saint Are. Approaching the famous 'Elbow', he looked sure to win comfortably, but Saint Are, who was receiving 17lb, started to cut into his lead close home and, in the end, he had to be driven right out to win by 1¾ lengths.
Win he did, though, and in so doing made Aspell the first jockey since Brian Fletcher, in 1974, to win back-to-back Grand Nationals. Winning owner Trevor Hemmings, previously successful with Hedgehunter in 2005 and Ballabriggs in 2011, joined James Machell and Noel Le Mare as co-leading owner in the history of the Grand National.
