Reigning World and Paralympic Champion Mark Rohan, finished fourth in the MH1 Road Race at the 2013 UCI Para-Cycling Road World Championships in Baie-Comeau, Canada.
The gold and silver medals went to newcomers - the Italian Luca Mazzone and William Groulx from the USA, with Paralympic silver medallist, Tobias Fankhauser edging into the bronze medal position on the line.
Rohan has dominated this event since 2010 when he won his first world title. While the Irishman started the race as one of the favourites, talent transfer riders, Mazzone and Groulx, were always strong opponents, having medalled in most World Cups this year.
Speaking after the race head coach, Brian Nugent said: "The bunch split up early on, and Mark made the first move. This group split again, with the Italian and American in the first break, and Mark and the Swiss rider chasing.
"He put so much work early on into trying to win. He really wanted to defend his world title, but it just didn’t work out."
