At one end of a shuttle course, athletes will be given a list of 42 words. They may try to store up to three at a time in short-term memory.
They run a full shuttle course, and attempt to find the three words in a large word search puzzle. When found, they return to the start.
If they don’t find all three quickly, they may elect to return to the start and find three more words. But the athlete can only circle a maximum of three words per round.
