What should I do if there is an obstacle in the water and I can't swim?

In some of our events there will be obstacles in the water . Most of these will be in shallow water and crossable by walking (in case you are unable to swim). If there should be any water obstacles that require swimming , you can talk to the marshals who will advise you to either complete the obstacle with a life jacket or the option of completely skipping the obstacle by performing burpees as a penalty.
