LONDON MARATHON 2026: ROUTE EXPLAINED

Published: 02/04/2026 | By: Jasmin Bodman

The London Marathon is known for many things – the crowds, the atmosphere, the sense of achievement – but one of its biggest highlights is the route itself. Winding through the capital, it’s a course packed with iconic landmarks, electric support and long, runnable stretches that make it one of the most memorable marathons in the world. Whether you’re taking part or cheering from the sidelines, knowing what to expect along the route can make the experience even better. So, let’s take a closer look at what’s in store across those 26.2 miles.

Running through the heart of one of the world's great cities, the London Marathon route is a large part of what makes the race so special. From its leafy start in Greenwich to the iconic finish on The Mall, every mile offers something worth looking forward to – whether you're the one wearing the bib or cheering from the pavement.

Here's everything you need to know about the 2026 course, landmark by landmark.

WHEN IS THE LONDON MARATHON AND WHERE DOES IT START AND FINISH?

The 2026 London Marathon takes place on Sunday 26th April. The race begins in Greenwich/Blackheath and finishes in St. James's Park, taking runners on a 26.2-mile journey through some of the capital's most recognisable streets.

Due to the sheer number of participants, the race uses a triple start to manage the field. You'll be assigned a specific start line in advance, so check your race information carefully beforehand.

It's also worth keeping an eye on official communications in the weeks leading up to the race, as the organisers do occasionally make minor adjustments to the route. Always check the latest version of the course map on the official London Marathon website rather than relying on previous years' information, just to be safe.

THE ROUTE, MILE BY MILE

The Start Line and the Early Miles – Greenwich to Mile 6

The race gets under way in Greenwich, and the opening miles offer a gentle introduction – there's a slight downhill gradient early on, which is welcome news for anyone trying to settle into their pace. The crowds are already out in force from the off.

Keep an eye out for Greenwich Park and the historic Charlton district as you find your rhythm in these opening miles.

South-East London – Miles 7 to 12

One of the most celebrated moments on the entire course comes here: Cutty Sark. Built in 1869 and one of the last surviving tea clippers, the ship is a genuine London landmark, and the crowd gathered around it is reliably one of the loudest on the route. It's a brilliant boost if your legs are starting to feel the early miles.

Beyond Cutty Sark, you'll pass through Deptford, Surrey Quays and Rotherhithe. The road widens along this stretch, giving you more space to settle into a comfortable stride.

Tower Bridge, Docklands and Canary Wharf – Miles 13 to 19

Crossing Tower Bridge at the halfway point is one of the great moments in marathon running – the views are spectacular and the noise from spectators here is phenomenal. After the bridge, the course moves onto the north bank of the Thames and into the Canary Wharf and Isle of Dogs sections.

This stretch involves a few twists and turns, so it's worth studying the route map carefully before race day to avoid any confusion mid-run.

Rainbow Row, Highway and Embankment – Miles 20 to 25

At mile 20, most runners will be digging deep. Fortunately, this section of the course delivers. Rainbow Row, established in 2022, celebrates the LGBTQIA+ community and is one of the most vibrant and supportive stretches of the entire race. Expect colour, noise, and a real lift when you need it most.

From there, the route rejoins the Highway back towards central London. Look out for Tower Hill and the Blackfriars Underpass as the finish begins to feel genuinely close.

The Finish – Embankment, The Mall and Buckingham Palace

The final miles take you along the Embankment, past the London Eye and Big Ben, before turning into Birdcage Walk and The Mall. With Buckingham Palace ahead of you and the finish line just beyond, this is the moment to give everything you have left.

It's a spectacular way to end 26.2 miles.

TIPS FOR RUNNERS AND SPECTATORS

April in London is famously unpredictable. It could be warm and sunny, or it could be grey and blustery – sometimes both on the same morning. Dress in layers and pack a lightweight, packable jacket that you can tie around your waist if it warms up. If it's a hot day, make use of every hydration station on the course and don't wait until you're thirsty to drink.

Runners have eight hours to complete the marathon. If you fall behind the pace required to finish within this window, race marshals will be on hand to advise you. In some cases, runners who have not reached certain points on the course by a set time may be redirected. If this is a concern, it's worth familiarising yourself with the cut-off points listed in the official race guide so there are no surprises on the day.

Bag drop facilities are available before the race – check your race pack for the designated drop-off and collection points, as these can vary depending on which start you're assigned to. The London Marathon is also designed to be inclusive for wheelchair users and hand cyclists, with a dedicated wheelchair race. If you're a wheelchair participant or spectating with accessibility needs, the official website has specific guidance on accessible routes and finish area facilities.

Other useful bits:

• Free travel on the London Underground is typically offered to marathon runners on race day
• Facilities at the finish include breastfeeding spaces, multi-faith prayer rooms and a sensory area
• Best spots for spectators: Cutty Sark, Tower Bridge and the Embankment offer the best atmosphere and are straightforward to reach by public transport. Plan ahead – it gets very busy
• Water, Lucozade Sport and energy gels are available at regular intervals along the route, along with bottle refill points. Toilet facilities are also dotted throughout – check the official route map before race day for exact locations.

FINAL THOUGHTS

Whether you're lining up at the start in Greenwich or cheering from the sidelines at Tower Bridge, the London Marathon is one of those rare events that genuinely lives up to the hype. The route winds through some of the most iconic parts of the capital, and it has a way of making even the toughest miles feel worthwhile.

If you're running it this year, you've put in the training and earned your place on that start line. Soak up every mile – the crowds, the landmarks, the noise – and enjoy the moment when Buckingham Palace comes into view. There's nothing quite like it.

Good luck, and enjoy every step of those 26.2 miles.
