Douglas County has moved to Level Red in its effort to slow the COVID infection rate. Because this limits the number of people we can have in the gym at any given time, we will be pausing ALL Rec classes, effective immediately, until we can safely host them again. Our team program can continue, but capacity limits may require some practice times to change. Coaches are contacting families with additional information. We look forward to the return of all our classes and programs as soon as it's safe to do so. ... See MoreSee Less

Douglas County is now at LEVEL ORANGE in its efforts to reduce the coronavirus spread. This new level lowers the number of people who may gather in a facility at the same time. For that reason, we will TEMPORARILY SUSPEND the majority of our REC CLASSES, effective Nov 30 (the Monday after Thanksgiving). This WILL NOT affect our Morning Pre-school program or our Team Classes. Please know we will resume all paused Rec classes as soon as the State and County feel it is safe for us to do so. The well-being of our gymnasts, your family and our staff are of the upmost importance. We greatly appreciate your understanding and continued support. ... See MoreSee Less

Douglas County is now operating under Level Red in the state’s efforts to reduce the spread of coronavirus. This new level means we must suspend all REC CLASSES, effective Friday (November 20).

This will impact some Team Classes, as we will be adjusting a number of our practice times to meet the new occupancy constraints.  Team members will be contacted by their coaches with additional details.

Our plan is for the return of our Rec classes and  programs as soon as the State and County feel it is safe for us to do so. The safety of our gymnasts, your family and our staff is of the upmost importance and we appreciate your understanding.

  • “20 mile has been a great impact on my daughter. Greatest level 4 coaching I have seen in a few years. My daughter has excelled in every area she has trained in. She is having fun but working hard!!”

  • “Our kids have been a part of 20 MAC since 2009. When you become part of this gym – you are part of a FAMILY. This facility doesn’t just promote that type of environment though – they demonstrate that in EVERYTHING they do with these kids. Over the last 4 years we’ve experienced summers filled with team outings to amusement parks, swimming pools and family BBQ’s; to winters random celebrations and holiday parties. The coaches are exceptional. They are not only producing elite gymnasts, but also instruct these kids on life skills;self respect, support & respect for their team, discipline to work hard and the importance of being considerate to others. The coaches are always accessible and communicate constantly with parents, keeping us informed of any challenges our kids may be experiencing and goals they may have set. This is a supportive community that we are proud to be a part of, that our kids love to attend, and that we encourage anyone looking for a place to call home – to join.”
