The InterChallenge has been designed as a step up from playgrounds. Suitable for ages 11 and up (yes, even adults can use the InterChallenge) we have installed many InterChallenges at Intermediates and Secondary Schools nationwide. The InterChallnge is built to withstand any amount of use by the older kids, teenagers and adults that we know will be seriously tested by the long, higher and harder events that the InterChallange presents.
