Prix Isonomy

The Prix Isonomy is a Listed flat horse race in France open to two-year-old thoroughbreds. It is run at Deauville over a distance of 1,600 metres (about 1 mile), and it is scheduled to take place each year in October.

History
The event is named after Isonomy, a successful racehorse in the late 19th century. It was formerly held at Le Tremblay with a distance of 1,100 metres. It used to be staged in early September.

The race was transferred to Évry in the 1970s. For a period it took place in late October or early November. It was contested over 2,000 metres for several years, and shortened to 1,800 metres in 1990.

The Prix Isonomy was run at Saint-Cloud over 1,600 metres in 1996. It was run at Longchamp over 1,800 metres in 1997 and 1998.

The race was restored to 1,600 metres in 1999. For brief periods it was held at Maisons-Laffitte (1999–2000), Saint-Cloud (2001–02) and Fontainebleau (2003–04). It started a longer spell at Saint-Cloud in 2005, and was switched to Chantilly in 2012. Since 2015 the race has been run at Deauville in late October.
