Runners are set to raise thousands of pounds to support people living with cancer when they take part in Norwich's biggest running event this autumn.

Macmillan Cancer Support has once again been chosen as the official charity for the 2012 Larking Gowen City of Norwich Half Marathon.

During the last five years, more than �160,000 has been raised for local charities and Macmillan Cancer Support has benefited from more than �80,000 in sponsorship from the 2010 and 2011 races.

Last year, more than 200 people joined Team Macmillan runners and it is hoped even more will run for the charity this year.

Helen Chapman, Macmillan's Norfolk fundraising manager, said: 'All of us at Macmillan are very proud to have been chosen as the official charity once again.

'Last year's event was a fantastic success and the money raised will all go to providing nurses and other specialist health and social care professionals, information services, financial help and advice and support via our emotional helpline for people affected by cancer.

'Just like last year, once runners have entered the race they can register to join Team Macmillan and they will be sent a pack containing fundraising and training advice, together with a special t-shirt and running vest.'

This year's Norwich Half Marathon will be held at the Norfolk Showground on Sunday, November 25.

Starting and finishing in the showground, the race follows a two-lap route through Easton, Honingham, Colton, Marlingford and the grounds of Easton College.

Some 3,000 people are expected to take part.

Hugh McGill, race director from City of Norwich Athletic Club (Conac), said: 'For the last two years Macmillan has contributed greatly to the race and we are delighted that once again they are the chosen charity to benefit.

'The encouragement from Team Macmillan at their cheering points and water stations is fantastic and encourages the runners to keep going.'

Mark Curtis, partner at Larking Gowen, added: 'Macmillan does a wonderful job in helping all those affected by cancer; patients, their families and carers.

'While the half marathon is about people having fun, we have been delighted with how runners have supported the chosen charities in the past and I am confident this will continue.

'We wanted to recognise this and are delighted that Macmillan has raised such a large amount over the last two years and are sure that runners will be out in force supporting them.'
