RUNNER Ade Walker was forced to hit the brakes to answer the call of duty on a gruelling race through Weymouth.

The Police Community Support Officer (PCSO) came to the rescue of a man who collapsed and feared he had broken his ankle on the Rodwell Trail.

He called 999 and made sure the casualty was okay before rejoining the gruelling 78.6-mile ‘Oner’ race – and still managed to finish 11th out of 40.

Mr Walker said: “There was an old guy who had gone over on his ankle.

“He said he had broken it but I think he had just sprained it.

“We carried him up to the Nothe and called an ambulance.”

The Oner 2009 event is the equivalent of three marathons. Mr Walker finished it in 21 hours and seven minutes.

The race started in Lyme Regis and followed the Dorset coastal path, along Chesil Beach and to Studland Bay.

There were check points every 10 miles, and runners who failed to reach each one on time were eliminated.

Mr Walker has raised more than £100 for Cancer Research so far. He picked the charity as two work colleagues have battled cancer.

He said he hoped to finish a lot higher next year, possibly in the top five – barring any incidents.

He added: “Thanks to everyone who has sponsored me so far.”

Mr Walker also recently took part in the Three Peaks Challenge with police officers from Weymouth.
