Szczepan’s jockey career started in 2011. In 2012-2015, he worked for Adam Wyrzyk, a Polish trainer, at his private training center in Podbiel. Since then his career has gone from strength to strength. In August 2013, upon winning his hundredth race, he earned the title of Jockey, and – in the same year – won his first Jockey Championship.

Since the 2014/15 season, he has been riding regularly in the UAE, where he competes with top jockeys from around the world, and continues to climb the rankings. His cooperation with successful local trainer, Ibrahim Al Hadhrami, proved to be a fruitful one.

Szczepan’s key achievements: 6x Polish Champion Jockey, 3x Derby winner, 3x Arabian Derby winner, 1x Grand Warsaw Prize, 1x Sheikh Zayed Bin Sultan Al Nahyan Cup, 1x Al Khalediah Poland Cup.
