McConnell is a four-time World Championship bronze medallist in the 4 x 400 metres relay; in 2005 and 2007, with the latter team setting the British record of 3:20.04, 2009 and 2011. Her individual honours include winning a 2002 Commonwealth silver at 400 metres, 2002 European Championship bronze at 400 metres, and 2006 Commonwealth bronze at 400 metres hurdles.
Lee McConnell attended Holyrood R.C. Secondary School in Glasgow before graduating from Loughborough University in 2000 with a degree in Sports Science.
Originally a high jumper (becoming Scottish champion in 1998, 1999 and 2000), before turning to the 400 m and then the 400 metres hurdles (winning Commonwealth Bronze in a PB time).
She was the Scottish 200 metres champion in 2002, and 2005. She also won the 400 m in 2001, and the 400 m at the AAA Championships in 2002.
Internationally, in 2002, McConnell won a bronze medal at the 2002 European championships in the 400 m, then added a Commonwealth Games silver in the 400 m. In 2003 at the European Cup, McConnell came second in both the 400 m and the 4 × 400 m relay. She went to finish fifth in the 400 m final at the 2003 World Championships.
Her personal best time over 400 m is 50.82 seconds.
After the 2007 season, McConnell decided to give up hurdling, as her transition from the flat had not been as successful as she had intended, and she returned to the 400 m flat. She broke the stadium record in the 400 m at the 2008 FBK Games, producing her fastest season opener.
At domestic level, McConnell later won the British 400 m title in 2008 and 2010, the British Inter-Counties 200 metres title in 2009, and two more Scottish 200 m titles (outdoor again in 2011 and indoor in 2013).
In addition to winning medals in individual contests, she has been a fairly successful relay runner. McConnell was known for participating in the Great Britain 4 × 400 m relay team at major events.
McConnell won bronze medals in the 4 × 400 m relay at the 2005 and 2007 World Championships. She ran the first leg in a team with Donna Fraser, Nicola Sanders and Christine Ohuruogu in 2005 and ran the third leg in team with Ohuruogu, Marilyn Okoro and Sanders in 2007, which a set a national record.
In addition at the World Championships, she ran the first leg for the 4 × 400 m relay teams that finished fifth in 2001, sixth in 2003, and fourth in 2009, also running fourth leg for the team that finished fourth in 2011.
McConnell alongside Fraser, Catherine Murphy, and Ohuruogu finished fourth in the 4 × 400 m relay at the 2004 Olympics, but could inherit bronze medals from this event as American athlete Crystal Cox was later found guilty of doping offences. Cox and not the US team had her medal revoked but that could still change.
At the 2012 Olympics, she ran the second leg as Great Britain finished fifth in the 4 × 400 m relay.
She has also accumulated relay medals from the 4 × 400 m event from the Universiade Games (in 2001), the European Championships (in 2002 and 2010) and the European Indoor Championships (in 2005, 2007 and 2011).
For Scotland, McConnell ran in the 4 × 400 m relay at the Commonwealth Games in 2002 and 2010 (where a national record was set).
McConnell missed the 2013 season after becoming pregnant with her first child. She returned to training nine weeks after giving birth to her son with a view to competing at the 2014 Commonwealth Games in her hometown of Glasgow – however she announced her immediate retirement from athletics in April 2014.
McConnell is a rugby union fan, and is supporter of the Glasgow Warriors and the Scotland national team.
