Charity runs, toy runs and memorial drives
Charity drive organiser
Big drives need calm organisation. Share one route with everyone, assign marshals as sweeps and keep the whole drive visible.
The problem
Large charity drives mix experienced and first-time group drivers, and one missed turn can send dozens of people the wrong way.

How Tarmac helps
How it works
- Step 1
Public group, easy joining
Make the drive public so participants can self-join with a link.
- Step 2
Marshals as sweeps
Assign several sweep roles to marshals spread through the drive.
- Step 3
One route, no drift
Everyone follows the same canonical route with no automatic rerouting.
