The running supporter is back!

At the 40th edition of the NN Marathon Rotterdam, supporters will once again be able to submit a personal video encouragement for their marathon heroes via hardloopsupporter.nl. The videos will be shown on four large screens positioned at the 34 kilometre point, the toughest point in the marathon. A record number of 8,105 videos were submitted for the 2019 edition, giving participants the last little push to get them over the finish line.

Go to hardloopsupporter.nl and upload your video.

Come watch at the Boszoom!
Supporters are welcome to visit the Running Supporter to cheer on your heroes and to watch the thousands of encouraging videos live and in person.
