Nancy Walker was walking her two-year-old dog, Raz, along the greenway at Moorend, Cleckheaton, when a cyclist collided with him at about 9.30am last Tuesday.

Nancy, a freelance riding instructor from Cleckheaton, said: "This man came really fast, hit Raz and the wheel pushed him to the ground.

"The man came off his bike and we had serious words. He said it was a cycle track and it was my fault Raz had been hit.

"My two dogs ran different ways along the greenway. I went looking for Raz, thinking I was going to find him dead."

She said Raz, a Spanish, Jack Russell-type dog, was not on a lead, but was close to her at the time of the collision. She added: "I've talked to other people who say they've had near misses with cyclists."

During her search for Raz she came across another woman whose dog had been hit by a cyclist – thought to be the same one.

Helga Walker (no relation), of Cleckheaton, was further along the greenway opposite Vine Street when a bike sped along the path and struck Archie, her nine-month-old Jack Russell. She said: "If there is a bike coming I put Archie on a lead but this time I didn't have a chance. The cyclist was going hell for leather.

"He hit Archie and I heard him say, 'Oh s**t!' But he was past in a flash.

"This has got to stop. Fair enough – the greenway is for cyclists as well as pedestrians, but they should ride responsibly."

Chairman of the Spen Valley Line Forum Donal O'Driscoll said the greenway was primarily a cycle route.

He added: "Cyclists should let people know they approaching by calling out or ringing their bells.

"But dogs should be on leads and kept under tight control on the greenway."
