Lynsey Sharp plans to bide her time before deciding whether to defend her European 800 metres title, despite having secured a place at the Commonwealth Games with victory at the Flanders Cup in Belgium.

With the selection deadline for Glasgow 2014 now less than two weeks away, the 23-year-old from Edinburgh delivered her most impressive performance since she returned from long-term injury, engineering a solo break in Lokeren to win in 2min 02.42sec, eight 100ths of a second inside the Team Scotland qualifying standard.

It means that Sharp will join Laura Muir and Emily Dudgeon in the ­Glasgow 2014 squad, but with her fight for full fitness not quite yet complete, Sharp will not rush into any declarations of intent for Zurich.

"The Commonwealths is hugely important for me," she said. "I only want to go to the Europeans if I'm in shape to defend my title. I've got so many things to do to get to that point. The first is qualifying and then getting training in. I just have to take it as it comes."

n Great Britain's men and women booked 4x400m places at next year's world championships in Beijing by making it through to last night's finals at the World Relay Championships in the Bahamas. The women were third in their heat in 3:27.49 with Eilidh Child leading the way.

"It was always going to be a hard heat having the Jamaicans and the Americans, they are the world silver and gold [medallists] from the world indoors," the Scot said. "We wanted to try and get through safely."

n James Campbell has been urged to stay patient in his javelin comeback after decrying his fourth place at the Bedford meeting on Saturday. It means the Scot, who threw a best of 67.78m, has just two more chances to secure a second Glasgow qualifying mark. Coach Toni Minichello, who guided Jessica Ennis to Olympic gold, told the 26-year-old not to panic. "It is the first time chucking for two years," he said. "Although disappointed, you need a little perspective."

n David Toniok, of Kenya, produced a closing burst to claim victory in the Edinburgh Marathon. His early lead was gradually eroded by compatriots Japhet Koech and Elicky Mase, but Toniok found an extra gear to win in 2:15:33, seven seconds outside the previous best on the circuit. "After 21 miles, I was feeling fresh and that's when I decided to go for it," he said.

Kateryna Stetsenko, of Ukraine, overhauled 2013 winner Risper Kimaiyo to win the women's marathon. Scotland internationalist Ross Houston and Northern Ireland's Gladys Ganiel were the victors in the half-marathon.
