The Olympic torch went out for a short time as it headed through the Lee Valley White Water rapids this morning.
It was a choppy journey and despite being kept well away from the water the flame went out briefly before being re-lit again a short time later.
The torch is now on its way to Hertford where thousands are lining the streets.
Today's spectacular finale on the Thames for the Olympic flame marked the end of a seventy-day journey around the British Isles.
