Your support is their fuel!
Personalize your messages for your favorite runners with the TCS Marathon Boost and submit them via the official app to send real-time encouragement.
On race day, your messages will shine on a giant screen between kilometers 28 and 29, at Quai des Tuileries.
Send as many Boosts as you like to support one or more runners.
We can’t wait to see your messages of encouragement!
