The Air Ambulance took a cyclist in her 20s to hospital with a serious head injury after she crashed into a Greenwich Park runner. 

Emergency services were called to the park at around 10.30am on March 28 after a smash during the Tough Run event.

The London Ambulance Service (LAS) confirmed they sent three ambulances to the scene as well as the helicopter.

A spokesman for the LAS said: "We treated a woman reported to be in her 20s for a serious head and shoulder injury.

"She was taken to the Royal London Hospital as a priority by the Air Ambulance."

Eyewitness Robert Gray, 58, said: "There was a tangled mess of bikes. I believe there was a cyclist coming down the hill right into another cyclist or a pedestrain.

"I don't know what the condition is of the person they took away in the Air Ambulance.

"There was an awful lot of emergency services, two or three ambulances and the Air Ambulance, there were lots of police cars."

The presenter, who lives at and runs No 16 St Alfeges Passage, added: "The police cordoned off a lot of the area.

"It's happened before, there was a fatality. It's very dangerous they come hurtling down at speed and often people wander into their path. 

"It's a saturday and the park is heaving with people. They should have some rules, speed limits. 

"I just hope everyone's okay."

Another eyewitness says the cyclist collided at 'high speed' with a woman who was running the organised run in the park. 

A spokesman for the Met Police confirmed the cyclist was injured and she is awaiting assessment at hospital.
