A free program for Android, by London Marathon Events.

If you are taking part in the London Marathon, you can use the Official TCS London Marathon App to track your progress and keep up with the latest running information for the event.

You can also get all the information you need in order to prepare for the race, such as:

How long the course is

When the race starts and ends

Where you will be on the course

How many miles you have covered

Who you will be competing against

The Official TCS London Marathon App has an interactive map so you can check out where all the runners are on the course, as well as keep an eye on the weather forecast and any potential route changes.

This app is also perfect for anyone who wants to track their progress in their own marathon or who is supporting an athlete competing in the event.
