Each team would have 4 people in the 100, 4 in the 200, 4 in the 400, 4 in the 800, 4 in the 1600, 4 in the 3200. They could start with the 3200 so teams could be spread out and each person runs their leg and passes the baton.
A runner could only do 3 legs max for his team.
They could run the field events as normal on the field.
Hurdlers would have to forego their events for this meet and be part of the relay event.
