Douvan spearheads Arkle challenge The brilliant Douvan is the star name among 37 entries for the Racing Post Arkle Challenge Trophy at Cheltenham. Last season's Supreme Novices' Hurdle winner is all the rage to claim Festival glory once more, having won each of his three starts over fences in devastating fashion for the all-conquering Willie Mullins. Douvan is one of seven potential runners for Mullins, with Supreme runner-up Shaneshill, Outlander and Killultagh Vic all in contention, while having other options. There are 14 Irish-trained entries in all, with Sizing John, Ttebbob and Velvet Maker other potential raiders. The home challenge includes the Nicky Henderson-trained duo of L'Ami Serge and Vaniteux, Gary Moore's exciting novice Ar Mad and Garde La Victoire from Philip Hobbs' stable.
