The Six Bar Competition returned to be part of Piazza di Siena’s programme in 2015, after being included from 1950 to 1954, in 1996 and 1997, 1999 and 2000 as well as from 2006 to 2008.
The first winner in 1950 was Piero d'Inzeo, ex aequo with both his horses, Eletto and Brando, while the last Six Bar Competition was won in 2023 by Emilio Bicocchi e John Whitaker who riding Flinton and Green Grass, jumped clear with the last upright measuring 1.95 metres.
This very spectacular class often ends with the last jump in the series raised to over two metres.
At the 2007 Piazza di Siena CSIO5*, British riders Nick Skelton riding Russel and Robert Smith riding Vangelis S shared a win, with the last jump measuring 2.15 metres, one of the world records for this kind of competition.
