A quintet of companies will be taking on the Morrisons Great Birmingham Run this Sunday in aid of city-based charity Cure Leukaemia.

The group have all vowed to fund-raise for the charity which was founded in 2003 by Professor Charlie Craddock and which helps bring drug and transplant treatments to blood cancer patients throughout the Midlands.

It also helps to finance the Centre for Clinical Haematology at Queen Elizabeth Hospital in Edgbaston.

The teams are all running as part of the Business Challenge - a special event that pits employees from the same company against others over the 13.1-mile course with a host of prizes on offer.

Business Challenge teams are between four and eight people and can be either mixed or single gender, with prizes on offer for small, medium and large companies.

Among those limbering up for the half marathon is a 20-strong cohort from the audit department at financial services firm KPMG in Birmingham.

They will be competing as four teams of five and also raising money for St Basil's, a charity that helps local young adults who are homeless or facing homelessness.

Also running on Sunday is a team from Edgbaston-based The Binding Site which specialises in producing antibodies used for the detection of certain cancers and immune system disorders.

The firm is an official partner of Cure Leukaemia. Chief executive Charles de Rohan ran for the charity at last year's event as well and at the time vowed he would never do it again.

Six staff from the Birmingham office of law firm Pinsent Masons - Martin Preece, Jade Morrison, Richard Moulton, David Meisel, Jodie Woollin and Dan Braithwaite - are also taking on the Business Challenge.

This is the third year in a row that Pinsent Masons has run for the charity, something supported by head of office Greg Lowson who is also a Cure Leukaemia trustee.

Making up the list is more than 50 competitors from Jaguar Land Rover and a further ten from its PR agency, London-based Pink Squid.

The car-maker has set a fund-raising target of more than £12,000.
