Oxford City’s Hannah England continues her preparation for the London Olympics when she competes in the Aviva Indoor UK Trials and Championships at Sheffield tomorrow.

The world 1500m silver medallist (right) will be competing in 3,000m in an attempt to improve her strength and stamina.

Meanwhile Jessica Ennis is continuing her build-up for the defence of her pentathlon title in Istanbul in March.

Irina Belova’s world mark of 4,991 will again be in Ennis’s sights.
