Track cyclist Matthew Richardson, a triple Paris Olympic medallist, has defected from Australia to represent Great Britain going forward.

AusCycling declared its “disappointment and surprise” after the 25-year-old confirmed he would now represent his nation of birth.

Richardson won silver in the Sprint and Keirin events in Paris, plus bronze in the Team Sprint, off the back of gold in the Team Sprint and Sprint events at the Commonwealth Games.

But any future medals will be won in British colours after the Union Cycliste Internationale (UCI) approved his switch.

Richardson moved to Australia as a nine-year-old, after being born in Maidstone, England, but he began cycling as a teenager once he was living in Perth.

He was recruited by the Western Australia Institute of Sport before becoming one of the world’s top track cyclists in the green and gold.

“The announcement of Matt’s switch is disappointing and came as a surprise. We also understand that the desire to compete for a country one was born in can bring forth strong emotions,” AusCycling Executive GM of Performance Jesse Korf said.

“Matt has been an intricate part of our sprint program for the past two years, enjoying many successes on the track across two Olympic Games, a Commonwealth Games, multiple UCI Track World Championships campaigns and several UCI Track Nations Cup and World Cup seasons.

“Our Performance program has made massive leaps in terms of culture and performance in recent years which is a testament to all athletes, coaches and staff — Matt included.

“The men’s sprint program is currently one of our deepest and exciting talent pools with strong programs across the country with the support of state and territory institute and academies of sport. We have many talented riders that now will see increased opportunity as we set our sights on LA 2028 as a stepping stone towards Brisbane 2032.”

Meanwhile Richardson explained “switching nationality was a difficult decision, and not one I took lightly. It was a personal choice, made after careful consideration of my career and future. It’s not something I decided on quickly or easily.

“I deeply respect Australia and the Australian Cycling Team, and it will always be a part of who I am. As this new chapter in my life begins, I would like to sincerely thank the coaches and support staff who have worked with me over many years in Australia.

“Special mention to Midland Cycle Club, WAIS and AusCycling, with personal thanks to the two biggest coaching influences in my career — Clay Worthington and Matt Crampton. I want to say a huge thank you to my teammates for everything we’ve been through together. You’ve been there for the highs and the lows, and I’m so grateful for all the support, laughter, and hard work we’ve shared.

“I hope you can understand and support me as I continue to give my best in the sport I love.”
