Tiffany Porter

She is the sister of Cindy Ofili, another elite-level sprint hurdler with dual British and American nationality; Ofili, too, chose to represent Great Britain internationally. Unlike Porter, Ofili had never represented the United States as a junior. Both sisters made the final of the 100 metre hurdles at the 2016 Summer Olympics.

Porter began 2014 by winning a bronze medal in the 60 m hurdles at the World Indoor Championships. Then in August, she ran 12.80 to win a silver medal in the 100 m hurdles at the Commonwealth Games in Glasgow, behind Sally Pearson of Australia. Two weeks later, she won the European Championships in Zurich, with a time of 12.76. In September, at the IAAF Continental Cup, she broke the UK record with a time of 12.51 secs, finishing behind Dawn Harper-Nelson of the USA.

Porter won a bronze medal in the 100 m hurdles at the 2013 World Championships. In 2014, she won a silver medal representing England at the Commonwealth Games. Later in 2014 she took her first major title, a gold medal at the European Championships, becoming the first British woman to win a European title in the event. Her personal best of 12.51 is the current British record. She is also a two-time medallist over 60 m hurdles at the World Indoor Championships.

In 2013 Porter switched coaches from James Henry to Rana Reider, and moved to Loughborough to train with Reider's group at Loughborough University's High Performance Centre. At the 2013 World Championships in Moscow, she won a Bronze medal in the 100 m Hurdles in a personal best time of 12.55 seconds, just one hundredth of a second off Jessica Ennis' British record of 12.54.

UK Athletics head coach, Charles van Commenee gave Porter the responsibility of the team captaincy ahead of the 2012 World Indoor Championships in March; she was subsequently labelled a "Plastic Brit" after refusing (or being unable) to recite the words of the British national anthem in a press conference.

In 2012 Porter was nominated for "European Athlete of the Month" twice. In March she was nominated along with fellow Brits Katarina Johnson-Thompson and Yamile Aldama. She was nominated again in May, this time with Hannah England and eventual winner Jessica Ennis.

On 29 May 2011, at the Fanny Blankers-Koen Games, Porter broke Angie Thorp's 15-year-old British record of 12.80s in the 100m Hurdles with a run of 12.77s. Thorp said that losing her record had made her "devastated". She stated that if a British-born athlete, for example Jessica Ennis or Sarah Claxton, who at the time both had personal bests of 12.81s, had broken her record she would have been "the first to congratulate", but as Porter had transferred from the United States, she was "absolutely distraught".

Porter lowered her British record on 22 July 2011, with a time of 12.60s at the Diamond League meeting in Monaco, breaking her previous personal best of 12.73s (set when she was still a US athlete). Her record was broken on 3 August 2012 by Jessica Ennis in the London Olympics heptathlon achieving 12.54s. In September 2011 she was nominated for "European Athlete of the Year". In October 800m runner Mariya Savinova was announced as the winner.

Porter married American hurdler Jeff Porter in May 2011, and began to compete under her married name in July 2011, initially as Tiffany Ofili-Porter, then simply as Tiffany Porter. She graduated from the University of Michigan with a PharmD (Doctor of Pharmacy) degree in 2012.

As an American athlete, Porter represented the United States at the inaugural NACAC Championships winning a silver medal. However, at the end of the 2010 season, she changed her allegiance to Great Britain. Commenting on her switch, she said: "I knew I was going to perform no matter what vest I had on. I have always regarded myself as British, American and Nigerian. I'm all three."

Tiffany Porter (née Ofili; born 13 November 1987) is a track and field athlete with joint British and American nationality who specialises in the 100 metres hurdles. She represented the United States as a junior, but began representing Great Britain in 2010 on joining the senior ranks after moving to England and competed for Great Britain at the 2012 Olympic Games in London.
