Short answer - no! Although CHALLENGE: Basic was designed for young men ages 13-18, we have had much interest from young men outside those ages, as well. For eleven and twelve year olds, there is an "Intro" track where they can participate in the training and instruction, but their routine is slightly more relaxed. They receive a lot of benefit from learning spiritual lessons and teamwork from a young age, and they become more prepared to keep up with the rigors of CHALLENGE (and life) as full recruits when they get older.
