Axel Pesek is a French equestrian who started riding at age three and reining at age 7. In 2017 he purchased Uncle Sparky from Bastien Bourgeois, and within months the pair began winning individual world junior championships.

At just 18 years old, Pesek (now always accompanied by Uncle Sparky), is vice-champion of France Pro before being selected for the World Equestrian Games of Tryon (USA) in 2018. The two accomplices qualified for the final and finished in 13th place.

The following year, the pair won a double silver medal—team and individual—at the Young Riders World Championship in Grivins (SUI).
