Hercules Wimbledon AC sprinter Dwayne Cowan made an impressive debut over 400m when he stormed to victory in a Southern Men's League match at Horsham on Saturday.

Despite never running the distance before, Cowan finished almost 40 metres ahead of his nearest rival as he crossed the B race in 48.9 seconds, impressively faster than the 51 seconds clocked by his clubmate Hamed Agboke in winning the A string event.

The 28-year-old, who switched to athletics from football two seasons ago, clocked the fastest Hercules Wimbledon time over the distance since Esmond Ferns posted 48.6 seconds in the Surrey championships at Wimbledon Park in 1997.

His time also ranks him eighth on the Hercules Wimbledon all-time list, which is headed by Olympic 400m hurdler Robin Woodland's 48.1 set at the Surrey championships at Motspur Park in 1959.

Hercules Wimbledon also gained maximum points in the 1,500m, with Fred Slemeck and Kieran White taking the A and B races.

White, who won the opening Surrey road league race of the summer in Richmond the previous weekend, also took second place in the 5,000m, with Matt Sharp finishing runner-up in the B race.

Slemeck was also second in the 800m, with teenager Cassian Hyde clocking a lifetime best of 2:02.5 in taking third place in the B race.

Max Mondelli, Hercules Wimbledon's reigning Surrey men's U17 and Surrey schools intermediate boys 100m champion, made a cautious start to his 2013 outdoor racing programme by taking third place in the 100m in 11.4secs - Richard Agyapong won the B race in 11.5secs.

The fastest Hercules Wimbledon sprinter was Joseph Chukwuadinula who took his non-scoring race in 11.2. He was also second his 200m match race in 23secs and linked up with Agboke, Devonte Casely-Hayford and Ciaran O'Duffy to help the sprint relay team to second place.

In their opening Southern Women's League Premier Division match at Guildford, Camilla Magni set a hat-trick of veterans women's over 40 club records when she competed for the Hercules Wimbledon team. Her record-breaking efforts came in the 100, 200m and 100m hurdles.

Former Commonwealth Games pole vaulter Alison Murray also set a club veteran over 45 100m record.

In a tough match, the only Hercules Wimbledon winner was Surrey indoor long jump champion Emily Martin who took her specialist event with 5.61m. She was also fourth in the shot and javelin.

Ruth Wallace won the women's 3,000m in a personal best of 10:20.35 which chopped more than eight seconds off her previous best time set in June 2011.

At the Richmond parkrun on Saturday, Jonathan Cornish beat a 281-strong field to win in a personal best of 16:47, taking 80 seconds off his previous best for the event.

Marathon husband and wife team David and Claire Grima were in action in the Wimbledon Common parkrun, where David was third in the men's race in a personal best of 17:23, slicing five seconds off his previous best set in May 2011.

Claire was first woman in 18:41, with teenager Matt Gibbons 12th out of almost 400 runners in 18:48.

Over 45 veteran Tom Cheetham also set a personal best of 19:37 in finishing 27th. Hannah Fernando was second woman in 19:58.

Cheetham won his second race of the weekend when he took the Volunteers Foundation 10km race on Wimbledon Common on Sunday in 39:43.
