Between 1991 and 2008, Seymour was beaten only twice in the Irish cyclo-cross championships and that was by Roger Aiken in the 2004/05 season and then the 2007/08 season. Seymour has been the principal rider for earning UCI points so that the Irish National Mountain cycling team could get a place at the 1996, 2000 and 2004 Summer Olympic Games in the Mountain Bike competition.
Seymour has been an Olympian at the 2000 Sydney Olympics and 2004 Athens Olympics as well as representing Ireland at the UCI Mountain Bike World Championships and UCI Cyclo-cross World Championships.
In the cyclo cross and mountain bike disciplines, Seymour dominates the Irish calendar and also competes World Cup mountain bike and cyclo cross races. Robin’s father Geoff is involved in cycling in Ireland and has organized the National Mountain Bike championships in 2004 as well as being the Irish National team manager for the International Mountain bike events.
The two person team that Seymour and Owens rode under was called Podge and Rodge whether this team name was due to possible sponsorship by the famous Irish television puppets Podge and Rodge or whether it was just due to the humorous name is unknown.
