Police have confirmed they won’t be investigating an incident where tacks were spread over the closed roads of the 88 mile Etape Cymru.
Six cyclists punctured and one motorcycle escort rider was left stranded after the low level attack during yesterday's sportive in North Wales, ridden by 1,700 participants.
The incident didn't puncture most rider's enjoyment of the Wiggle-sponsored, closed-road event, however. Nick Rusling, CEO of Human Race, who organised the event said: "It's very disappointing. It's also dangerous – it could have caused riders serious injury. It's not a sensible way of showing dissatisfaction towards the event.
"There are plenty of positives though. The feedback from the cyclists has been amazing; a lot are saying they'll come back. And there has been roughly £500,000 worth of spend in the local area."
Other closed-road events have suffered similar attacks before. The Etape Caledonia in Scotland has been repeatedly targeted by saboteurs. And earlier this year, the New Forest Spring sportive was targeted too.
