A record 36,500 runners took part in this year's London Marathon, many in weird and wonderful costumes. Matthew Ball sent in this photo of the start.
Troy Tindill dressed up as Shane Warne for the event. "The crowd loved it!" he said.
Dave Pickup did the race dressed as a bakewell tart.
These convicts basked in the sunshine at the start of the race in Blackheath.
Soaring temperatures of at least 21C didn't seem to deter the fun runners from dressing up.
The water stations were vital in this the 27th London marathon. This picture from Emily Norton shows children helping to prepare bottles for the runners at the six mile mark.
But despite having water and medics on hand, St John Ambulance reported a "high" number of runners collapsing on the finish line.
Huge crowds turned out to line the route and cheer the runners on as they made their way through the capital to the finishing line on the Mall.
Dave Heeley and his guide dog Wicksie did the race as a warm up. Dave, 49, is planning to run seven marathons in seven days next year.
Many of those taking part were raising money for charity. In 2003, runners collected £31.8m for good causes.
Martin Lel of Kenya won the men's race in two hours, seven minutes and 41 seconds. Others, like this runner in Bermondsey, took much longer.
