LONDON (AP) — One of rowing's great modern-day partnerships has ended after two-time Olympic champion Heather Stanning announced her retirement from the sport.

The 31-year-old Stanning won the gold medal with Helen Glover in the women's pair at the last two Olympics, extending their unbeaten record that dates to 2011. They were the first British women rowers to win Olympic gold. They also earned two world championships.

Stanning will continue to serve in the British Army.

Stanning and Glover were "one of the most exceptional crews that world rowing has ever seen," said David Tanner, performance director at British Rowing.

Glover is set to continue her rowing career.
