This race is the opposite of leapfrog. Instead of jumping over the backs of his teammates, the last person in line tunnels through their legs toward the finish line. For adults, this is the most tiring event by far.
WHAT YOU NEED:
A start and a finish line.
WHAT YOU DO:
Line up families so they're facing the finish line. At the start of the race, the last person in line drops to the ground and crawls through the legs of everyone in front of him. Not until he stands up and spreads his feet can the next person at the end of the line start crawling. The team continues tunneling in this way until it reaches the finish line.
