Margie Pedder

Sibella Margaretha Pedder (born 27 June 1980) is an English former competitive swimmer who specialised in butterfly events. She is the former British record holder in both the 100m butterfly and the 200m butterfly and became a semifinalist in the 200 m butterfly at the 2000 Summer Olympics. Later she captured a bronze medal when her nation England hosted the 2002 Commonwealth Games. During her sporting career, Pedder trained with the Portsmouth Northsea Swim Club under head coach Chris Nesbit and later at the University of Southern California under Mark Schubert.

Pedder competed in a butterfly double, as a member of Team GB, at the 2000 Summer Olympics in Sydney. She eclipsed FINA A-standards of 1:00.74 (100 m butterfly) and 2:10.57 (200 m butterfly) from the British Olympic Trials in Sheffield. On the first day of the Games, Pedder placed thirtieth in the 100 m butterfly. Swimming in heat four, she escaped from last at the turn to edge out Finland's Marja Pärssinen by 0.41 seconds for the seventh seed in 1:01.53. Three days later, in the 200 m butterfly, Pedder advanced to the top 16, and finished her semifinal run with an eleventh-place time and a lifetime best of 2:10.49.

When her nation England hosted the 2002 Commonwealth Games in Manchester, Pedder enjoyed the race by a massive roar of a home crowd, as she took home the bronze in the 200 m butterfly at 2:11.60, extending a delightful feast for the Brits with a two–three finish.

Pedder also competed in U.S collegiate swimming for the University of Southern California, where she became a three-time All-American in the mile and 800 freestyle relay.
