Weather for runners


London Marathon weather statistics

 

Runners will be looking for a fine spring day to help them get around the 26.2 mile course in London. A mild, but not hot, day with a light breeze will help those charity runners who will still be completing the course past noon. Those conditions will also help the professional runners get around the course in world-record time - as we saw in 2002 when Khalid Khannouchi shaved a few seconds off his own world-record.

The event has seen some extremes of weather in the past 10 years. 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.

In 2016 Eliud Kipchoge from Kenya won the men's race in 2:03:05, securing the current men's course record, and second fastest marathon time in history. Jemima Sumgong of Kenya won the women's race with a time of 2:22:58, while in the wheelchair race, Marcel Hug from Switzerland secured the top spot in the men's race and the US's Tatyana McFadden won the women's race for the fourth consecutive year.

The course

Since the London Marathon began in 1981, its runners have raised £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.
