Athletes will today descend on London's Docklands for the second day of the world's largest triathlon. Around 13,000 competitors are expected to take part over the two days.
The A4202 Park Lane Southbound is closed between A40 Cumberland Gate (Marble Arch) and A4 Hyde Park Corner due to a rehearsal for the Olympic triathlon event.
Hyde Park Corner closures will be in place on all approaches until around 07:00. The ORN (Olympic Route Network) will also have changes during this time which could cause a delay for drivers in the area.
