Let’s begin!

The London Marathon 2025 Route In Detail

The London Marathon distance is 26.2 miles/ 42.2 kilometers. The terrain of the marathon is closed-off roads and pavements and has a total elevation gain of between 119m and 138m, making it a mostly flat course with only one small rise.

The course which has barely been changed since 1981 makes up one of the most iconic marathons in the world and is one of the six Abbott World Marathon Majors.

The London Marathon route is famous for good reason, runners are able to see an incredible selection of London’s famous landmarks.

The route winds out of Greenwich Park and leafy Blackheath, it runs through Charlton, turns west past the famous Cutty Sark then loops through Greenwich and across Tower Bridge into Shadwell. Runners will reach Canary Wharf and the London Eye and then the course runs along the Lower Thames past the Tower of London through Trafalgar Square where runners get to pass the famous Landmarks of Big Ben and the Houses Of Parliament, then it’s the final stretch to The Mall in front of Buckingham Palace at St Jame’s Park.

Let’s have a detailed look at the course right from the start line…

The Start Of The London Marathon

The marathon begins with a triple start of different colors and number zones.

There are three different start points depending on your running bib color…

  • Red: Southern Greenwich Park. 
  • Green: St John’s Park
  • Blue: Shooter’s Hill Road

Each start area (Red, Green, Blue) has eight zones – numbered 1 to 8 – and you will be informed of your Start Zone when you register at Expo.

The zone you have been allocated to is based on your predicted finish time when you entered. 

Note: You cannot change your Start Area or move to an earlier Start Zone. But if you think your predicted finish time is now too fast, you will be allowed to join a later Start Zone.

When you register for the race you will receive your start color.

Mile 1-6 Of The London Marathon

Mile one to three takes you from the start line in leafy Blackheath, through Charlton. If you’re running from the red start line, from St Johns Park, or Shooter’s Hill Road. Mile 3 is where all the runners merge onto the same course.

Runners will then make their way through Woolwich and into Westcombe Park. Heading west, mile six is where participants enter Greenwich on Trafalgar road.

Mile 7-10 Of The London Marathon

After passing the famous Cutty Sark at mile 7 runners will then head to Deptford and then Surrey Quay at mile 9.

Runners will reach their first Lucozade Sports Drink table here and then run closer to the Thames along mile 10.

Mile 11-12 Of The London Marathon

Runners make their way towards the photogenic Tower Bridge in mile 11 and in mile 12 they cross the bridge heading towards the Tower Of London. Runners are almost halfway at this point.

Runners are now on the other side of the Thames running on the highway. The halfway mark is crossed just after mile 13 and runners make their way toward Narrow Street.

At mile 16 they make their way down to Crossharbour and into Mudchute.

Now that we know everything there is to know about the route, let’s have a look at the London Marathon cut-off time…

What Is The Average London Marathon Time?

Let’s first get this straight… all marathon times are “good” marathon times… It’s an incredible achievement at the end of the day and you should be extremely proud of yourself… no matter your finishing time.

With that being said, a lot of people consider a ‘good’ London marathon time to be under four hours – as this is better than the average. 

The average time for male finishers is 3 hours and 48 minutes. 

The average time for female finishers is 4 hours and 23 minutes. 

This is according to The Mirror which worked out the average finishing time from the 42,549 people that competed in the 2019 London marathon.

RunRepeat mapped global running participation, covering 107.9 million race results from more than 70,000 events from 1986 to 2018. 

In the end, they found that, in the UK, the average marathon finish time was 4:37:09. (This was done in 2019)

The Cut-Off Time For The London Marathon

The cut-off time for the London Marathon is 7 hours. 

Runners can only receive a medal and feature in the marathon results if they complete the course in 7 hours. (Of course, if you don’t finish in the 7 hours you can still try to finish the route, although roads will be reopened by then, so be careful.)
