Relay race:
A cleared out area is presented to each team. There are the runners, the gatherers, and the builders. The gatherers collect resources such as trees, water for the builders and runners, and stones for the foundation. The runners put logs into carts and race them to the builders. The builders take the resources and create a cabin as quickly as possible.
Treasure hunt:
At a starting point, each team receives a clue to be read on a runestone. Each time must uncover what the clue means and travel to the next checkpoint. After a while at the end, a chest full of good stuff is at the end. The team decides how to divide the goods.
