Hannah Mills Career

Her path from junior champion to double Olympic gold medallist spanned roughly two decades of consistent international competition.
Junior and Early Senior Career (2001–2011)
Mills announced herself to the wider sailing world in 2001 by winning the British Optimist Championships.
Two years later, she represented Great Britain at the 2003 Optimist World Championships, finishing fifth overall and first among female competitors.
She transitioned into the youth 420 class and won the World Sailing 420 Women’s World Championship in 2006 in Las Palmas.
By 2010, she had won the 470 women’s junior world title. In 2011, Mills paired with Saskia Clark and the duo took silver at the 470 World Championships in Perth, signalling they were genuine Olympic contenders.
That same year, she won silver at the Skandia Sail for Gold Regatta and the Weymouth and Portland International Regatta.
The consistency she showed across major regattas in 2011 made her and Clark strong favourites heading into London 2012.
Olympic Breakthrough and Rio 2016 (2012–2016)
Mills and Clark competed at the 2012 London Olympics, held at the Weymouth sailing venue.
On 10 August 2012, the pair won a silver medal in the Women’s 470 class, narrowly missing gold as New Zealand edged them out in the medal race. Following London, the partnership continued to develop.
On 10 December 2014, Mills and Clark were robbed at knifepoint in Rio de Janeiro while preparing for the Games, a jarring incident that did not derail their preparation.
By 2015, they had taken silver at the 470 World Championships in Haifa. At the 2016 Rio de Janeiro Olympics, Mills and Clark claimed gold in the Women’s 470.
They entered the medal race with a 20-point lead, winning three races and finishing in the top eight across all 10 races.
The gold secured Mills the title of Olympic champion for the first time. That year, she received the Female World Sailor of the Year award, recognising her as the top women’s sailor on the planet.
Tokyo 2020 and Retirement from Olympic Sailing (2017–2021)
After Clark retired following Rio, Mills partnered with Eilidh McIntyre in early 2017.
The new pairing was immediately competitive, winning the World Cup Series final in Santander, Spain on their first outing together, then taking silver at the 2017 470 World Championships in Thessaloniki.
In 2019, Mills and McIntyre won the 470 Women’s World Championship in Enoshima, Japan, Mills’s second world title in the class.
That same year, she launched the Big Plastic Pledge, a movement backed by the International Olympic Committee calling on athletes globally to reduce single-use plastic in sport.
On 4 August 2021, Mills and McIntyre won gold in the Women’s 470 at the Tokyo Olympics, held in Sagami Bay.
The victory made Hannah Mills the most successful female Olympic sailor in history. She subsequently announced her retirement from Olympic sailing.
SailGP, Athena Pathway, and Women’s America’s Cup (2021–Present)
Mills joined Sir Ben Ainslie’s Emirates Great Britain SailGP Team in 2021, becoming the first female sailor to join the squad.
She took the role of on-board strategist, responsible for tactical decisions and wind analysis during races on F50 foiling catamarans capable of speeds above 60 mph.
In 2022, she and Ainslie co-founded the Athena Pathway programme to accelerate opportunities for female and youth sailors in professional racing.
That same year, the IOC appointed Mills an Officer of the Order of the British Empire for her services to sailing and the environment.
In 2024, Mills helmed the Athena Pathway team in the inaugural Women’s America’s Cup in Barcelona.
In 2025, she played a key strategic role as Great Britain won their first SailGP Grand Prix Championship title, also becoming the first team to win both the season championship and the Impact League award in the same season.
