The business world can play its part in the half marathon with the Arcadis Business Challenge inviting firms of all shapes and sizes from across the Midlands to compete for fastest-time trophies and all-important bragging rights.

Eleven members of the West Midlands Combined Authority, including Mayor of the West Midlands Mayor Andy Street CBE, will be taking on the Great Birmingham Run.

The ‘Mayor's Movers' team is raising funds for Cure Leukaemia's £1m appeal to expand the globally-significant Centre for Clinical Haematology at the Queen Elizabeth Hospital in Birmingham.

All children who finish will receive a goody pack, a medal and bottle of water.

The last date to enter the Mini and Junior Runs to have packs posted is 10am, Thursday, October 5. Entries to collect packs will stay open until 5pm on Friday, October 13, after which entries for both events will be closed.

Among those taking part is grandfather Stuart Bailey, from Billbrook, near Wolverhampton, who has finished more than 50 running events dressed as everyone from Santa to the Jolly Green Giant to raise more than £20,000 for good causes.

Stuart will be donning his 7ft Peppa Pig costume to line-up for the Mini Run on Saturday and the half marathon on Sunday to raise money for The Royal Wolverhampton NHS Trust Charity after they cared for his grandson George.

And ‘Blind Dave' Heeley won't be running one long distance event on October 15 – but two.

The Black Country running legend will be attempting to complete both the Birmingham International Marathon AND Great Birmingham Run in one day – a total of 39.3 miles.

It's all part of lifelong West Brom fan Dave's efforts to conquer the Great Run Company's entire, 25-strong events calendar in 2017 – understood to be a world first for a blind pairing – in aid of the Albion Foundation.

David Hart, Communications Director for the Great Run Company, organisers of the Simplyhealth Great Birmingham Run, said: “We've been overwhelmed with the response to this year's Great Birmingham Run, the Birmingham International Marathon, and the Mini and Junior runs.

“The whole weekend will see thousands of people of all ages taking to the streets of Birmingham and the Alexander Stadium. If you want to join in, it's worth signing up now.”
