A 28-year-old drunk driver has been jailed for five years and three months over the hit-run death of a cyclist in the Perth suburb of Cottesloe.

Tim Anderson, 26, was training for a charity ride when he was hit by a car driven by Ross Murray in March.

Mr Anderson was cycling north on Curtin Avenue heading for home when he was struck from behind at about 8:00pm.

He hit the windscreen of the car and was then dragged with his bicycle along the road.

Murray abandoned his vehicle and fled the scene.

Mr Anderson was taken to hospital where he later died as a result of his injuries.

The court heard Murray had been drinking heavily with a workmate in the hours before the crash.

He pleaded guilty in the District Court to causing the death of another while under the influence of alcohol, and failing to render assistance.

Murray will be eligible for parole after serving three years.

Dozens of Mr Anderson's family and friends packed the courtroom to hear the sentence.

The family says the jail term is inadequate.

His father Ian said outside court the sentence does not fit the crime.

"It is impossible to understand how he could leave Tim by the side of the road critically injured and alone to die," he said.

Mr Anderson called the action despicable.

"His intoxicated state, dangerous driving and actions were completely reckless, irresponsible and unforgivable," he said.

The fatal crash led the Cyclists Action Group to call on the Government to complete the Perth to Fremantle cycleway which currently stops at Grant Street station in Cottesloe.

The group said cyclists are then forced to share the road with heavy traffic.

A memorial bike ride is planned for November.
