28 April - Will you be competing in the London marathon or cheering on the competitors? Check the London weather forecast. 

Runners will be looking for a fine spring day to help them get around the 26.2 mile course in London. A mild, fine day with a light breeze is forecast, which could potentially help charity and professional runners alike get round the course in record time. Good condtions in 2002 helped Khalid Khannouchi shaved a few seconds off his own world-record.

The event has seen some extremes of weather, in 2004 it was particularly wet and windy, and Evans Rutto, the eventual winner of the professional men's race, slipped and fell in the poor conditions.

A record number of runners crossed the Start Line of the Virgin Money London Marathon in 2017, with more than 39,400 completing the gruelling 26.2-mile journey from Blackheath to Westminster, making the 37th edition of the race the biggest in its history by 347 runners.

Of the 39,487 who crossed the Finish Line in The Mall by 18:15, one established two new world records, one broke a course record, one took a record-breaking seventh London win and 39 broke Guinness World Records, making the 2017 event the greatest ever London Marathon.

Mary Keitany ran alone for all but two of the 26.2 miles, powering clear of the greatest field ever assembled to take her third London title in a world record time of 2:17:01. Only Paula Radcliffe has run faster, when she set the mixed-race world record in 2003, but she had to watch from the commentary box today as Keitany smashed her women-only record of 2:17:42.

The course

Since the London Marathon began in 1981, its runners have raised over £830 million for charity, making it the largest single fundraising event in the world.

The London Marathon course passes many of the historic sites of England's capital city. Some of the landmarks runners will take in are: 

  • Cutty Sark and the National Maritime Museum - runners will see these London landmarks around mile six.
  • Tower Bridge - runners cross the bridge at mile 12.
  • Runners will pass the tallest building in the country, 1 Canada Wharf in the centre of Canary Wharf, at mile 19.
  • Runners will then pass Cleopatra's Needle, one of the pair that originally stood at Heliopolis in Egypt.
  • Nearing the finishing line, mile 25 sees the runners pass some of the most recognisable landmarks of the city with the Houses of Parliament and Big Ben.
  • With a mile to go, runners take their last few steps down The Mall before completing the race in front of Buckingham Palace.

Check the weather forecast for the London Marathon on Sunday.
