The Course - TCS London Marathon
The London Marathon will use bib chip technology to time all participants in the mass event for the first time in 2021. The timing chip is affixed to the back of the participant’s bib number (running number.) The chip is read when a participant passes over mats at 5K, 10K, 15K, 20K, halfway, 25K, 30K, 35K, 40K and at the Finish.
