[1] Aged 10, Janssens frequented the Beringen, Geldrop and Amsterdam tracks and as a teenager he schooled and trained a greyhound to finish second in the Belgian Championships.
He then moved to England and gained a position at Linda Jones' Imperial kennels in Lakenheath where he was working alongside Mark Wallis.
[6] Towcester closed in 2018 and Janssens joined Central Park[7] but despite the forced move 2018 was another good year with a second qualification for the 2019 Trainers Championship where he finished runner-up behind Angela Harrison.
In 2020, Patrick Janssens won his maiden Trainer of the Year title ending the eight-year reign of his former boss Mark Wallis.
During February 2021 Janssens announced his return to Towcester as an attached trainer and in July he reached the pinnacle of the sport by winning the 2021 English Greyhound Derby with Thorn Falcon.
