Rugby
Genyn took up wheelchair rugby shortly after his accident in 1993, and was classified as a 1.5 player. He represented Belgium at the 2004 Summer Paralympics in Athens where the team ended sixth overall. As well as his Paralympic appearance Genyn was also part of the Belgium team at two IWRF World Championships, at Christchurch in 2006 and Vancouver in 2010. His highlight as a Wheelchair rugby player came in 2009 when he was part of the Belgium team that beat Sweden in the final of the 2009 IWRF European Championship. Genyn followed this with a second Paralympic appearance when Belgium qualified for London 2012 after finishing third in the 2011 European Championship. Genyn's wheelchair rugby career came to an end in November 2013 after he broke his leg.
Athletics
After the end of his wheelchair rugby career Genyn switched to track and field athletics. Genyn switched to sprinting as he always saw himself as the fastest member of the Belgian rugby team. After being classified as a T51 athlete, Genyn appeared at his first major international competition when he represented Belgium at the 2014 IPC Athletics European Championships in Swansea. He took part in two events, the 100 and 400 metres sprints. Genyn won two silver medals, beaten in both by Finland's Toni Piispanen, another ex-wheelchair rugby player. The following year Genyn met Piispanen again at the 2015 World Championships in Doha. This time the tables were reversed with Genyn pushing Pispanen into the lower medal places as he took gold in both the 100 metre and 400 metre races, setting championship records in both. In the build up to the Rio Paralympics, Genyn entered the 2016 European Championships in Grosseto. He won gold in both the 100 and 400 metres sprints setting a new worldrecord time of 1:18.09 in the 400m event. During the 2016 Summer Paralympics, Genyn managed to win the gold medal both in the 100m as well as in the 400m T51 event. One year later he successfully defended his titles at the 100 and 400 metres events at the 2017 World Championships in London.
