FOUR police officers aim to raise thousands of pounds for charities this weekend at the Flora London Marathon.

Caroline Davies, Dave Barker, Will Cousins and Karl Lowe have been preparing for the run since last August.

The officers, from Darlington, are raising funds for Children Nationwide, Cancer Research UK and Bliss.

Caroline has raised £2,100 for Children Nationwide, a charity carrying out research into childhood illnesses.

The group have been sponsored by Pickfords Removals. Morton Park car firm Links Motors also donated £165.
