Dai Greene

In light of further injury issues, which resulted in him missing the 2016 Summer Olympics in Brazil, in November 2016 Greene was stripped of his UK National Lottery funding by UK Athletics, and hence omitted from UKA's world-class performance programme from 2017 onwards. Despite this further setback, Greene continued to train through 2017. Free of injury for the first time in several years, Greene began returning to form through 2018, culminating in winning the British championships in July of that year, sealing qualification for both the 2018 European Athletics Championships, and the inaugural Athletics World Cup.

Greene's injury problems continued throughout 2013 and 2014, interrupting his training regime and preventing him from successfully defending his 2011 World crown in Moscow where Greene was eliminated in the semi-final. An attempt to retain his Commonwealth title also ended in the semi-finals, while running nearly two seconds outside his personal best. Greene resultantly withdrew himself from consideration for the 2014 European Athletics Championships, because of lack of form and a failure to make the agreed qualification time.

At the Diamond League event in Paris on 6 July 2012, Greene ran a personal best of 47.84 secs in finishing second to Javier Culson to move even closer to the British record in the 400m hurdles. Greene was selected to captain the Great Britain athletics team for the 2012 London Olympics, as one of the favourites for a medal. In the first round of the 400 m hurdles Greene won his heat in 48.98s, the fastest time of round. In the semi-finals Greene ran sluggishly, finishing fourth and only qualifying for the final as a fastest loser. In the final Greene finished fourth behind 2004 Olympic champion Félix Sánchez, surprise American Michael Tinsley and Javier Culson, running slower than he had in the semi-final. Post-race Greene admitted huge disappointment, and blamed disruption to his training caused by a knee injury in the winter. Greene also ran in the final of the 4 × 400 metres relay, as the British team finished fourth, just 0.13 seconds off a medal.

On 1 September 2011, at the World Athletics Championships in Daegu, South Korea, Greene won the gold medal, overtaking a strong field in the final straight.

In 2011 Greene was named an Ambassador for the Jaguar Academy of Sport.

On 31 July 2010, he won the Gold Medal in the 400m hurdles at the European Athletics Championships in Barcelona, with fellow Welshman Rhys Williams getting the silver. On 10 October 2010, Greene won the gold medal in the Commonwealth Games in Delhi.

After his coach Blomqvist decided to return to Sweden for family reasons, from 2009 Greene moved to the University of Bath, to allow him to train under coach Malcolm Arnold, supported by the Wells Sports Foundation. He was later joined by fellow Welsh 400m hurdler Rhys Williams, who became his training partner.

The 2009 outdoor season saw Greene making his first impact on the senior circuit. In June he set a meet record and a new personal best of 48.62 seconds to win the 400 m hurdles at the Josef Odlozil Memorial in Prague. This was a significant improvement from his 2008 best of 49.58 seconds and made him top of the European rankings for the first time. Competing for Team GB at the 2009 World Championships, Greene won his heat with a strong first round performance of 48.76 seconds. He followed this with a new personal best in the semi-finals, finishing in 48.27 seconds to take second place behind Bershawn Jackson. He finished 7th in the final of the men's 400 m hurdles, and received a silver medal for the 4 × 400 m relay, despite only running in the semi-final, being replaced in the final by Michael Bingham.

Moving to Cardiff to be coached by Benke Blomqvist, Greene had his first success on the junior athletics circuit in 2005. He won the silver medal at the 2005 European Athletics Junior Championships, finishing with a personal best time of 51.14 seconds. The following year he competed in his first senior tournament, the 2006 European Athletics Championships, but he failed to progress beyond the heats with a run of 50.66 seconds. His age-group success continued, however, as he won the gold medal at the 2007 European Athletics U23 Championships with a new best of 49.58 seconds. He beat Frenchman Fadil Bellaabouss by a narrow margin to mark an impressive return, following an ankle injury which had ruled him out for six weeks of the season.

David "Dai" Greene (born 11 April 1986) is a Welsh hurdler who specialises in the 400 metres hurdles, competing internationally for both Wales and Great Britain. In a 'golden' sixteen-month period between 2010 and 2011, Greene won the World, European, Diamond League and Commonwealth titles in the event, in addition to winning the event as part of both the European Team Championships and the IAAF Continental Cup. He is the second fastest British man over the 400 m hurdles, behind the British record holder, Kriss Akabusi.
