London’s biggest sporting event is upon us. For every one of the 59,000 runners in this year’s London Marathon, there will be plenty of eagle-eyed watchers at home keen to follow their updates.
If you’re at home wondering how your loved one is faring in the race, never fear! The TCS Marathon App has all the information you need about your friend or family member’s progress at your fingertips.
Simply download the app (available on the Apple App store or Google play store). If you cannot download the app, you can use the tracker on the official London Marathon website.
Then, simply enter the name or preferably, the bib number, of whichever racer you’re looking for. You can find out where they are on the interactive map as well as receive notifications when they have crossed certain timing mats.
The app has a feature called "Wayfinder" for spectator tracking, and the "TCS Marathon Boost" allows supporters to send heart-warming messages on the huge screen monitors the appear throughout the course.
In order for the app to work effectively, your runner must ensure they have GPS switched on their device participating in the race.
