These two hurdlers have probably been the stars of the winter season. Sweden's Kallur broke the world record and Cuba's Robles almost broke Colin Jackson's record.
Who knows what Dayron can do? It is a quick track in Valencia and they will be two great races.
Dayron will also be a real hope in the hurdles at the Beijing Olympics and China's Liu Xiang may find he actually steals the show.
Kallur is supreme and I can't see anybody getting close to her.
