Do I need to use the Official App for the virtual event?

We encourage all virtual TCS London Marathon participants to use the Official App as this provides the best experience. However, you're welcome to use any tracking device to record your 26.2 miles. We'll email all virtual participants with instructions on how to upload a time via an alternative device in the build-up to Marathon Day.
