Here’s a sample of a challenge included in London’s Race to Erase last year:

Covent Garden Market
The Covent Garden Market wanted to spotlight the variety of vendors they had, and for the teams to have some fun. Each team was required to find six vendors in the Market. Three of the vendors had song sheets and three had action sheets. Once the team had found all six vendors, a volunteer got the attention of everyone in the food court and they sang “Itsy bitsy spider”, “I’m a little teapot” and “Skinamarinky dinky dink” with the actions.
