How can my friends and family view my live location?

The following information only applies to participants in the virtual TCS London Marathon: you can add two supporters to view your live location on Event Day in the ‘Live location’ section of the Official App powered by TCS. You’ll need to set them up by 23:59:59 BST on Sunday 2 October. Please note this function relies on you having a successful GPS connection on Event Day.
