About Marathons in London

The famous marathon distance (26.2 miles) is loved by participants and spectators alike. People run marathons for many different reasons, either for a loved one, for a personal goal or for a great cause. In 2016, Shannon Foudy became the one millionth runner to complete the London Marathon.

What are the best marathons?

If you're thinking of running a marathon, London is not only the most popular but also one of the flattest around, so it's a great place to push for a PB. But, it is balloted and you can expect stiff competition for places. If you do miss out on a place, there are still many other great races right here in London. The Richmond Marathon, part of the RunFest, has a comparatively tiny field (around 400 entries) but follows an especially pretty route through Kew Gardens. If you need something a little more low key, Hermes Running do the Thames Meander Marathon & Half in spring, summer and winter.

How long will it take me to run a marathon?

The average time for London Marathon finishers in 2018 was 3h48m for males and 4h23m for females. Both these times are about 20 minutes faster than the global average. Top tip, don't worry about what others are doing, or who overtakes you, stick to your game plan and enjoy the ride.

If you're interested in knowing how fast you can really go in London, the world record for women was set in London by our very own Paula Radcliffe in 2003 at 2h15m and is still proving tough to beat. The men's record was beaten in Berlin in 2018 by Eliud Kipchoge and at 2:01:39 is pushing close to breaking the elusive 2 hour barrier.
