Quite a tough call really. I think Epsom certainly has the more difficult track with all its undulations and twist. The fact that there is only one shot at the Derby makes it more of a unique target to hit. It’s the quality of horses that give the Arc its diamond-studded appeal because a lot of Derby winners contest in it.
I narrowly have slight preference for the Arc … but only just!
Looking back, it almost seems an injustice that Frankel never contested in either of them
