Ride leaders, marshals and sweep riders
Lead and sweep roles
Organiser, lead, rider and sweep — Tarmac gives each role the controls and view it needs.
The problem
Leading and sweeping a ride is hard work. Without shared positions, sweep only knows someone's missing when they arrive at the stop without them.

How Tarmac helps
How it works
- Step 1
Organiser
Creates the group, invites people and edits the route before the start.
- Step 2
Lead
Starts and pauses the ride for everyone.
- Step 3
Sweep
Sees who is behind and where, so nobody is left behind.
