Employees from Luminus joined thousands of runners to take part in a gruelling and challenging muddy run.

Seventeen members completed the Insane Terrain five and 10k obstacle course around Washbrook Farm, Doddington.

The course involved climbing over hay bales, through tubes, running across a giant lily pad and through thick sludgy mud.

Luminus tradesman Tom Meech said: “It was great to take part in Insane Terrain with Team Luminus. It was really challenging but the team spurred each other on and there was great team spirit amongst us.”

It was the first time any of the team had taken on this kind challenge and already they are hoping to take part next year.

Dr Chan Abraham, Luminus Group Chief Executive added: “I'm very proud of all our employees who took part. Their commitment and perseverance was evident on the day.”
