The Paris Marathon is big. With 52,078 starters in 2023 it was bigger than the London Marathon and Chicago Marathon. If you’re turning up to cheer on a friend or loved one from the sidelines, it helps to know when they’re approaching the area where you’re standing, or if you’ve missed them and need to hightail it to the next viewing spot.
To do that, your best bet is to use live tracking feature of the Paris Marathon app, which is available to download on iOS and Android. It’s also useful for people cheering on from afar, who want to see how their runner is progressing.
