ARC Trials day took place this year on Sunday at Chantilly, which is where the big race itself will be run on October 2nd as Longchamp is being renovated.

A quick spin on Google Earth (the bane of many a clerk of the course’s life) reveals that Chantilly rises only about six feet over the duration of its 12 furlongs, compared to Longchamp’s 20 feet, but that the former is more demanding in the final half-mile.
