The 2026 London Marathon is set to take place on Sunday, April 26, with a record-breaking number of entrants. With 50,000 runners participating in the 26.2-mile race, spotting a specific person among the crowd can be challenging. However, the official London Marathon app makes it easy to track loved ones or celebrities in real time.
Download the Official App
The 2026 London Marathon tracker app is available for free on both iPhone and Android devices via the App Store and Google Play. It is essential to delete any previous versions, such as the 2025 app, and install the current one to ensure proper functionality. The app is designed for both runners and spectators, offering a range of tracking features.
How to Track a Runner
Once the app is downloaded, navigate to the tracking section. You can search for a runner by entering their name or bib number. After finding the desired runner, simply press the 'add' button, and they will appear on your personal tracking list. There is no limit to the number of runners you can track simultaneously.
The app sends notifications whenever a tracked runner passes a 5-kilometer split point. It also provides an estimated finish time based on the runner's current pace, allowing you to plan your cheering schedule accordingly.
GPS Live Location Sharing
If the runner is carrying a smartphone, they have the option to share their live location with up to three spectators. This feature uses GPS technology rather than the chip attached to the bib, offering continuous real-time updates instead of only at 5K intervals. This is particularly useful for spectators who want to move along the route to catch glimpses of their runner at multiple points.
Wayfinder Feature
The app includes a Wayfinder tool that helps spectators identify when tracked participants are expected to reach specific landmarks along the marathon route. Wayfinder provides detailed information about each landmark and gives live directions to those locations via public transport or on foot, using integrated Google Maps or Apple Maps. This feature ensures you can be at the right place at the right time to offer support.
With approximately 800,000 spectators expected along the route, being prepared is key. The official London Marathon app is an indispensable tool for anyone planning to follow the action and support a runner in the 2026 event.
