Trainer-jockey Josef Vana added to his incredible haul of victories in the Velka Pardubicka when Tiumen struck gold in the Czech Republic.
The 57-year-old brought up another milestone with a clinical defeat of stablemate Sixteen, the odds-on favourite who was bidding for a third consecutive victory in the race.
Vana has now won the Pardubicka six times as a jockey and seven times as a trainer.
Numero Due finished third in the marathon contest, while Oliver McKiernan’s Irish raider Il En Reve was tailed off.
The British travelling party were out of luck.
Lucky Nellerie, trained by Ferdy Murphy, ran out at the sixth fence.
Jockey Keith Mercer reported: ‘He jumped super, but pulled quite hard.
‘He tried to run out and I couldn't pull him back on course.’
Kim Bailey's Lucky Luk crashed out early on, while Mister Big finished in mid-division.
Trainer Charlie Mann said of the latter: "He jumped well and gave Noel (Fehily) a great spin around.
‘It's very hard taking on these horses in their own backyard.
‘The cut in the ground wouldn't have helped him.’
Fehily added: ‘He gave me a great ride, but from four out I was always fighting a losing battle over his stamina.’
Graham Smith's Super Lord fared best of the British, finishing seventh.
