Teams who wish to register
for the eco challenge may sign up at registration, at no cost.
These teams must start and finish Saturday's competition with
a full tank. At the start of Saturday, once the tank is filled,
a seal will be affixed to the fuel filler. At each refueling stop,
and at the final MTC, the seal will be inspected, then broken
to refuel, and a new seal affixed. The team's fuel cans will be
weighed before and after the refueling, and this weight will be
recorded as a measure of the fuel added. The fuel zone marshals
will be judges of fact for verifying the seals and weight of fuel
added, and verifying that the tank is full at the finish.
