Extinction Rebellion protestors have cycled to Heathrow today, blocking the road as part of a campaign against the airport's expansion.
Footage taken by one of the participants who is running on the road alongside the cyclists shows the large group passing through red lights.
Police cyclists can be seen escorting the protestors and one warns the jogger to get off the road, saying: 'You're gonna have to be careful mate, you're going to get hit.'

One of the bikes was even designed to look like a bulldozer, in reference to Boris Johnson promising when he was first elected as MP for Uxbridge to 'join John McDonnell in lying in front of the bulldozers' if the expansion of Heathrow goes ahead.
When the cyclists arrive at the airport, they will perform a 'bulldozer lie-in' and act out the future destruction bulldozers will cause when they begin building the controversial Third Runway.
Johnson and McDonnell were invited to attend today's protest by the eco activists.

Local anti-Heathrow campaigner Christine Taylor, said: 'Residents in villages to the north of Heathrow have repeatedly faced the destruction of their communities by a proposed third runway.
'Now, with communities around the world suffering the effects of climate change, it's time to scrap the runway and cancel the bulldozers once and for all.'
Police allowed the protest to take place today on Bath Road but insisted it must finish by 3.30pm.
Heathrow's third runway is a controversial topic and one taken up by climate activists as a key battleground.

They say that building the runway is incompatible with the Government's target to reach net zero carbon emissions by 2050, saying increased air traffic will only exacerbate the current problem.
Kevin Anderson, Professor of Energy and Climate Change at Manchester University, said: 'At every level, expanding Heathrow flies in the face of any scientific, mathematical and moral interpretation of our Paris commitments.
'The strong support by many politicians for the expansion demonstrates just how thin their veil of concern is for our own children's prospects as well as the lives of poorer and more climatically-vulnerable communities.
'Set against this failure of integrity and strategic leadership, it is imperative that civil society steps up to fill the vacuum left by those purporting to be in charge.'
