ACORN TRAILSRunners at a 10k trail race in Glasgow were sent in the wrong direction by a prankster who impersonated a marshal and buried signs marking the course.
Acorn Trails said someone moved a route arrow and impersonated a race organiser to send about 30 competitors on a 2.5km (1.5 mile) detour on Sunday.
The organisers said they could “laugh about it” but warned the safety of runners had been compromised.
They apologised to competitors for the “mischievous interference” and offered affected runners a discount on entry to their next event.
