Push to Talk Communication at Roparun 2025

When hundreds of teams and thousands of participants take on a 500 km relay race like Roparun, reliable communication is essential. That’s why our partner Flash selected GroupTalk as the communication platform to secure voice coordination across both the French and Dutch routes during this year’s event.

“This year we wanted to take another step in professionalizing our operations,” said Hugo van Hees, Race Director at Roparun. “We had been using two-way radios, but the lack of channel separation in the control room created chaos. With the new solution from Flash and GroupTalk, everything worked flawlessly.”

Using the GroupTalk app and PC dispatch (command & control), the Roparun control room gained full control over communication flow—separating channels between team leads and general participants, and gaining real-time GPS visibility of all units on the course. With just one button press, field users could instantly get in touch with dispatchers.

“Especially during incidents, you want communication to be fast and easy,” van Hees explained. “GroupTalk made that possible, and Flash supported us on-site throughout the race to make sure everything was working perfectly.”

“We’re extremely satisfied with the collaboration,” said van Hees. “The communication solution significantly contributed to the safety and success of this year’s Roparun.”

GroupTalk is proud to support safe and efficient communication during large-scale events like Roparun—enabling our partners to deliver operational excellence when it matters most.
