Marilyn Chinwenwa Okoro is a Britishtrack and field athlete. She finished third in the 800 metres at both the 2007 and 2008 IAAF World Athletics Final. She was on the bronze winning 4 × 400 m relay at the 2007 World Championships in Athletics. She represented Great Britain at the Beijing Olympic Games in 2008 and finished sixth in the semi-finals. She was part of the 4 × 400 mrelay team which finished fifth in the final of the 2008 Summer Olympics although the team was later upgraded to bronze medal position following disqualification for doping offences of the teams finishing in third and fourth place. She attended Stowe School, Buckinghamshire, and on 26 June 2007 graduated from the University of Bath with a B.A. degree in Politics and French, then starting her first season as a full-time athlete. She speaks four languages and sings in the jazz band The Felonius Monks. Marilyn suffered an injury plagued 2009 outdoor season, though she battled through the pain barrier to finish a very credible 8th in the World Championships 800 m final in Berlin. Okoro was also included in the squad for the 4 × 400 m, but was not selected in the line-up to run in the final. , Lee McConnell and Nicola Sanders Marilyn had a limited race schedule in 2010, but returned to a degree of form when taking bronze at the UK championships. Subsequently, Okoro was selected to challenge for a medal in the 800 m alongside Jenny Meadows and Jemma Simpson at the 2010 European Championships in Barcelona. She finished 4th in her semi-final, therefore did not progress to the final. Okoro recovered from that disappointment to run the second leg in the 4 × 400 bronze medal winning quartet alongside Nicola Sanders, Lee McConnell and Perri Shakes-Drayton, clocking 52.0 seconds for her leg. She also ran in the heat running 51.8 seconds. Vicki Barr replaced Shakes-Drayton in the heats. Okoro has been criticised heavily for her front running tactics, most notably by UK Athletics head coachCharles Van Commenee, who described Okoro's performance in the 800 m at the 2009 European Athletics Indoor Championships as "naive and unprofessional". Following her non-selection for the 800 m event at the 2012 Summer Olympics, Okoro accused Van Commenee of being "a bit of a bully." Marilyn changed coaches during 2013, and then made the decision to move to the USA. She represented Team England at the 2014 Commonwealth Games in Glasgow, competing in the 800m. Ranked 179th in 2019, PB from 2008.
