Hanretty began
figure skating in 1995. As a
single skater, he was coached by John Christie and Diane C. Dewar in
Edinburgh and
East Kilbride. He switched to
ice dancing in 2004. He competed briefly with Lauren Bradshaw. Hanretty and American ice dancer
Christina Chitwood decided to team up on 31 December 2005 and began training together properly in May 2006. Their training was disrupted by Chitwood's contraction of
mononucleosis (glandular fever). They made their debut in January 2007 at the
British Championships at the
National Ice Centre in
Nottingham, England, finishing in 7th place. Chitwood/Hanretty won bronze at the
2008 British Championships at
IceSheffield in
Sheffield in January 2008. In the summer of 2008, they were selected by the
National Ice Skating Association (NISA) to join the Great Britain Squad (also known as Team Skate G.B.). This enabled them to represent Great Britain in elite international competitions. In September 2008, Chitwood/Hanretty made their international debut at the
2008 Nebelhorn Trophy in
Oberstdorf, Germany, where they placed 10th. In November of that same year, they won the bronze medal in their second international competition, the
Pavel Roman Memorial in
Olomouc, Czech Republic. Chitwood/Hanretty placed 4th at the
2009 British Championships at the
National Ice Centre in
Nottingham, in January 2009. However, their international success earlier in the season enabled them to qualify for the
2009 European Championships in Helsinki, Finland. At the event, they competed alongside the first-ranked British team,
Sinead Kerr /
John Kerr, and finished 18th. In autumn 2009, Chitwood/Hanretty placed 8th at the
2009 Nebelhorn Trophy in
Oberstdorf, Germany, fourth at the
Ice Challenge in
Graz,
Austria, third at the
2009 NRW Trophy in
Dortmund, Germany, and fourth at the Mont Blanc Trophy in
Courmayeur, Italy. In November 2009, Chitwood/Hanretty won the bronze medal at the
2010 British Championships at
IceSheffield in Sheffield. They were ranked third overall in the 2009–10 NISA National Rankings, based on the personal best scores achieved during the 2009–2010 season. They retired from competition in 2010. Chitwood/Hanretty received funding from the
Lloyds TSB Local Heroes initiative. ==Later career==
