The event follows last year’s Shrewsbury Marathon which took place around the town centre.
Around 2,000 runners including shropshirelive.com’s Martin Childs are due to take part in the event which leaves the West Midland Showground at 10am.
The one lap route takes in four miles of countryside before runners head towards Shrewsbury town centre and back to the showground for the finishing line.
Last year the full marathon raised around £30,000 for charity.
