Four more members of the Irish team for Rio 2016 have been confirmed, including the first female track cyclist to compete for Ireland at the Games.

The Olympic Council of Ireland announced that Shannon McCurley will compete in the women's Keirin.

The Keirin, unfamiliar to most non-cycling fans, is a 2km or eight lap race where a motorised bike, known as a derny, paces riders for the first 1.4km; gradually increasing the speed.

The derny then pulls off leaving the riders to compete against each other.

The talented sprinter previously won a bronze medal for Ireland in the Scratch Race at the European U23 Track Cycling Championships in Portugal in 2011.

Australian-born McCurley declared for Ireland in 2011.

McCurley will be joined on the cycling team by cousins Nicolas Roche and Dan Martin, who will both take part in the men's road race.

Both men are regular features in the Grand Tours, with Martin recently finishing third in the Criterium du Dauphine, a stage race regarded as a good indicator ahead of the Tour de France.

Roche, a member of Team Sky, finished in 24th place overall in last month's Giro d'Italia.

The OCI also announced that Natalya Coyle will join Arthur Lanigan O'Keeffe on the modern pentathlon team.

Coyle, who also competed at London 2012, teamed up with Lanigan O'Keeffe to take Mixed Relay gold at the Modern Pentathlon World Cup in May.

The 25-year-old finished ninth at the Games four years ago and will be hopeful of an improved performance this time out.

The latest additions bring the Irish squad to 54 athletes from 11 different sports.
