Jelle Wallays is the brother and nephew of racing cyclists
Jens Wallays and
Luc Wallays. He was coached by his uncle in his early racing career and competed in his first race at the age of 14. The start of his first year as a professional in 2011 was marred by a knee injury, however a few weeks after returning to competition he took the best result of his season at the
Belgian National Road Race Championships, where he finished third behind
Philippe Gilbert and
Gianni Meersman. A winner of the
Paris–Tours Espoirs in 2010, Wallays won the
2014 Paris–Tours having been in a breakaway that went in the opening kilometres of the race, making him the only rider to win the under-23 and elite men's editions of Paris–Tours. He added a second victory in the race in 2019. In 2015, he won the
Dwars door Vlaanderen by attacking a group of three other riders a kilometre away from the finish line. Wallays joined for the 2016 season, with a focus on working as part of the team's
sprint train. In October 2020, Wallays signed with the team for the 2021 season. ==Major results==
