How do I log into the Official App powered by TCS?

To log into the Official App powered by TCS you need three pieces of information:

  1. Your Booking Reference Number – we last emailed this to all participants on Tuesday 28 September when we announced that the App was available to download
  2. Your email address (the one associated with your TCS London Marathon entry)
  3. Your date of birth

Once you have downloaded the Official App powered by TCS from the App Store or Google Play, open it and click on ‘I am a participant’ and then ‘next’. You will be asked to choose three Quicklinks for your homescreen (you can skip this step if you prefer).

Then, to log in for the first time, click on ‘My Marathon’. You will be prompted to add in the three pieces of information listed above and then you’ll be good to go.

Once you’ve logged into the App you want need to do this again, unless you log out.
