Hercules Wimbledon’s leading woman sprinter Emily Martin warmed up for the coming summer track and field season by twice improving on her 60m best at the Surrey indoor championships at Sutton Arena on Saturday.

Martin, 21, won her heat in 7.81 seconds to take two-fifths of a second off her previous best, set when finishing runner-up in the same meeting in 2007.

She then improved to 7.74 in finishing second in the final.

Her silver medal added to her already extensive collection of Surrey gongs, which goes back many years to 2002, when she took bronze in the girls’ U15 long jump.

Last summer, she took a bronze medal in the senior women’s 200m, while her last gold medal-winning performance came in 2007 in the junior women’s long jump at Kingsmeadow.

That year, she also won the 100m and was third in the high jump.

Another Hercules Wimbledon runner in action at Sutton was teenager Eleanor Hahn-Smith, came fourth in the girls’ U15 60m in a time of 8.35.

She had finished runner-up in her heat and semi-final in 8.39 and 8.40 respectively.

Richard Agyepong just failed to reach the semi-final of the junior men’s 60m, finishing fourth in his heat in 7.40.
