Two great champions, two colossal reputations - only one could survive

The Racing Post asked ten big racing names to write about what they think is the greatest race of all time, before putting their choices to a public vote. In part one of the series, Brough Scott nominates Arkle v Mill House in the 1964 Cheltenham Gold Cup.

The day remains like no other. For it is what happened before as much as afterwards that still sets Arkle and Mill House's 1964 Gold Cup in a special category of racing heaven.

Never before, and certainly never since, have two such heralded champions come together for so anticipated a showdown. But while it was the start of Arkle's superstardom, it's easy to forget how much Mill House had been hailed as a second Pegasus. Why, hadn't he already put Arkle in his place four months earlier in the Hennessy?
