I need someone to list some creative "tribe" names for Youth Bootcamps/Residentials

I would like someone to come up with some creative names for youth bootcamps residentials. We already have 2; one for creatives, and one for aspiring entrepreneurs.

Now what we need is a list of 10 names for a sports bootcamp, and 10 names for a general outdoor activities bootcamp. Names need to be creative and represent a group of people, and must end with an 's' (e.g. ballers, challengers, rangers).

Need 20 names total; 10 for sports bootcamp and 10 for general outdoor activities bootcamp.

Would ideally like this done within the next 6 hours (by 3.30 / 4pm GMT, Friday 13 March '15).
