Although there will be many people taking to the streets of London to share support to the many runners, not everyone will be able to make it.
However, there is still a way for you to show your support to the hard-working runners taking on the 26-mile run.
The BBC is showing full coverage of the London Marathon throughout the morning and afternoon, meaning you can stay warm and watch from home.
How to watch the London Marathon from home
The BBC will be hosting special coverage hosted by Gabby Logan as 50,000 runners take on the London Marathon.
The coverage will cover both the men’s and women’s elite races, which were both won by Kenyans last year in the form of Alexander Mutiso and Peres Jepchirchi.
While in the wheelchair races, Swiss athletes Marcel Hug and Catherine Debrunner took the crowns.
Joining Logan will be Andrew Cotter, Steve Cram, Paula Radcliffe and Tanni Grey-Thompson with commentary.
Plus, there will be reports from Abby Cook, JJ Chalmers, Jeanette Kwakye and Sarah Mulkerrins.
The BBC coverage of the London Marathon starts at 10am on Sunday April 27 on BBC One and BBC iPlayer and ends at 2pm.
How does the London Marathon tracker app work?
When you download the app, you will be taken to the homepage that gives you all the options and features available, including how to track a participant.
The app is available to download for both iPhone and Android users, and you can download it for either device via the website here.
You just head to the ‘Tracking’ section and search for the runner by their name or bib number.

It will then show the progress made along the route, and if you enable your GPS, the position of the runner will be more accurate.
Along with being able to track a runner, you can also find expert tips and advice, keep up-to-date with the Elite Leader board and find out results.
If you still have the app from the 2024 London Marathon, you will need to delete it and download the new app.
