Midlands companies of all shapes and sizes are in the running for corporate glory after signing up to take part in the Simplyhealth Great Birmingham Run Business Challenge.
The race's annual Business Challenge invites firms to compete at the half marathon in October for fastest-time trophies and those all-important bragging rights in the business world.
There are competitions for men's, women's and mixed teams of four or more runners from small, medium and large companies and organisations.
The four fastest collective times by participants are added up for each team to pick the overall winners and an engraved trophy is awarded for the winning team in each business size category.
Plus, any company that enters 12 employees or more also receives an engraved plaque.
The Great Birmingham Run reverts to its morning start time for 2018 after being put back to make way for the inaugural Birmingham International Marathon last year.
The 13.1-mile route will once again start and end in the city centre and take in some of south Birmingham's suburbs such as Edgbaston and Bournville.
More than 60 teams took part in last year's half marathon and 10K Business Challenges, from a variety of business sectors and sizes across the Midlands.
It is seen as a great way of raising funds for a workplace charity or foundation, motivating team spirit and supporting corporate social responsibility objectives.
Among the winners last year were HSBC and the West Midlands Combined Authority whose team, the 'Mayor's Movers', were led by Mayor Andy Street.
They were raising funds for the Alzheimer's Society and Cure Leukaemia respectively.
Already signed up for this year's Business Challenge are Thursfields Solicitors, Wesleyan Assurance and tax auditors RSM UK.
David Hart, partnerships director at The Great Run Company, said: "Taking on the Simplyhealth Great Birmingham Run Business Challenge is a great way of inspiring office morale and team building.
"While the challenge has an element of friendly competition, it's all about participation and getting active for the summer with one of the biggest events of the year to look forward to.
"We can't wait to see the thousands of runners on the start line."
