Course and distance to test Dawn’s limits

Is it just a question of stamina with favourite Dawn Approach ahead of this afternoon's Epsom Derby? Perhaps not, as the course is also a potential stumbling block to the horse, who often looked like he needed strong handling at the business end.

With the exception of minimal experience at the turn which comes shortly after the break over the seven-furlong trip at the Curragh, Dawn Approach’s ability to handle a turning track is an unknown - and even the Curragh outing hardly counts as the horses were in no rush to take the turn, moving right off to race the middle of the track.

Epsom - Tattenham Corner, in particular - offers a completely new test, which adds to the doubts over his suitability to today’s test.
