The best choice depends on your audience. For competitive teams, team sports tournaments like football, volleyball or padel work well. For broader groups, mixed formats are more popular. Combinations of sport, puzzles and creative tasks make sure non-sporty team members join in too.
Popular choices are obstacle runs and bootcamp formats with humour. City games with sporty elements and bespoke relay races also work well. Ask your team beforehand what appeals to them. That gives turnout and enthusiasm a real boost.
