Ruby Walsh has announced his retirement from racing after Kemboy led home a one-two for trainer Willie Mullins in the Coral Punchestown Gold Cup, the feature event on day two of the Punchestown Festival.

The 39-year-old rider opted to end his brilliant career in the saddle following a two-length victory aboard Willie Mullins' charge in the Grade One event. 

Walsh was seen to wave goodbye to the Punchestown crowd after Kemboy saw off the Cheltenham Gold Cup hero Al Boum Photo in fine style.

Walsh opted to partner Kemboy of Mullins' three runners and his decision was justified as the seven-year-old proved too good for his Cheltenham Gold Cup-winning stablemate in the Grade One feature.

Kemboy came unstuck at the first fence at Cheltenham as Al Boum Photo claimed the blue riband, but he gained compensation under a positive ride from Walsh.

British raider Definitly Red disputed the early lead with the eventual winner, but it was a duel between the Mullins' runners turning for home, with Al Boum Photo unable to go with Kemboy, who ran out a two-length victor.

There was a further 22 lengths back to the The Storyteller in third.

Walsh said: "He jumped really well. He quickened and quickened and quickened - he has pace and stamina and has a real knack of jumping."
