Bradbury Star has been competing over longer distances in recent years - his last victory at two miles was a novice chase at Kempton in October 1991.
But Josh Gifford's classy gelding is certainly a Cheltenham specialist. In November he won the two-and-a-half-mile Mackeson Gold Cup - his eighth success at the track.
Bradbury Star is also still entered in Thursday's Gold Cup, but the testing ground could persuade Gifford to chose the shorter race.
Miinnehoma, who is certainly being aimed at the Gold Cup, has been cut to 10-1 (from 12-1) by Ladbrokes. Last year's Grand National winner would be best suited by soft ground at Cheltenham, his trainer, Martin Pipe, has stressed.
