Pégase du Mûrier (born April 29, 2003) is a gray show jumping stallion registered in the Selle Français studbook.

Purchased at the Fences sales by a jeweler, he successfully completed the classic cycle of young French show jumping horses, before being entrusted at the age of 7 to a little-known rider, Sébastien Duplant, with whom he won the title of vice-champion of France Pro Élite in 2014.

That same year, he was snapped up by international rider Roger-Yves Bost, who went on to win numerous Grand Prix titles, particularly in 2017.

[6] This young rider took Pégase from Reynald Gras's stables in Aix-en-Provence at the age of 7,[8] when he was suffering from tendonitis and hadn't jumped for a year,[6] following a series of bad experiences.

[6] This gray stallion enabled the previously little-known Sébastien Duplant to "move from the shadows into the light",[6] forming one of the most talked-about French rider-horse pairs of the 2013 and 2014 seasons.

[10] He acquired Pegasus with the help of his French-Canadian sponsor Equiblue, who holds 99% of the shares, the remaining 1% being owned by his EURL Bosty Jump.

[12] Between 2014 and 2018, Roger-Yves Bost and Pégase du Mûrier scored eight international victories in Aachen, Paris, Shanghai, Stuttgart, Bordeaux, Geneva and Madrid.

[clarification needed][20] Roger-Yves Bost also describes him as a very sensitive stallion,[20] close to man, with a strong character on the track,[14] sometimes uncooperative.

[8] In training, he does little jumping, and only on bars less than a meter high; he works a lot on the flat with neck extensions, to relax him.
