The London Marathon is one of the biggest distance-running events in the world, bringing together people of all ages and abilities on one course.
Such an epic 26-mile undertaking means that entrants need all the support they can get, and thanks to advances in technology it’s now a great deal easier to track your friends’ progress than it was back in 1981, when the Marathon was born.
So whether you’re at home, on the go, or spectating around the course, here are a few tips on how to follow your runners throughout the day.
Official app and online tracker
The Virgin Money London Marathon ran its own mobile app for the first time in 2015, to make it easier for friends and family of participants to track the race as it progresses.
2017 is supposed to be the first year that this service will be available on Android, having previously been an iPhone exclusive.
