Every marshal on the course, one button away
A push-to-talk room for each team — course, finish, first aid, parking — on the volunteers' own phones. No radios to hand out at dawn and count back in the evening.
How it works
Create a room per team
Up to 20 people each; keep the rooms permanent and reuse them every year.
Send the links in the volunteer briefing
Volunteers open them in the phone's browser — or the Android app, to keep talking with the screen locked.
Press and talk
Hold the button to report; the coordinator's call to everyone cuts in when it matters.
Why organizers use SpeakMic
Rooms per team
Course, finish, first aid — each team on its own channel, without crosstalk.
Private calls
A marshal and the coordinator can talk one-to-one without tying up the channel.
No radio range limit
A 42 km course works as well as a stadium, as long as there's mobile coverage.
Frequently asked questions
How many volunteers can be in one room?
Up to 20 per room. For a bigger crew, create a room per team or sector — the coordinator can be in several.
What happens where there's no mobile coverage?
Online rooms need mobile data. For a sector without coverage, SpeakMic Offline for Android connects nearby phones directly over WiFi Direct and Bluetooth.
Can the coordinator reach everyone at once?
Yes. The room's host has a call to everyone that takes the floor from whoever is speaking — and reaches people in private calls too.
Does it work with the screen off?
In a phone browser the audio can stop once the screen locks; the SpeakMic Android app keeps the room running in the pocket.
