Look into Centreville Swim Club. Very nice coaches and flexible in terms of number of practices per week.

Herndon Aquatic Club has two "low maintenance" programs for the middle school/high school age groups at Herndon Community Center.

Age Group Gold 2 is for 11-14 and meets 4x week after school (although they are not strict about attending every session).

Senior Bronze is for 14-18 and meets 2x week at night.

HAC has had coaching issues for a number of years with a horrible head coach, but now has a new head coach who is light years better.

York, Tuesday/ Thursday at Yorktown or the 3x a week evening program at Oakmarr. Mostly HS swimmers who like swim, and don’t want to be competitive.

Potomac Marlins at Cub Run have programs for 2-3x a week for teenagers.

I was going to recommend York as well. Good club, great philosophy.

are you with machine now? did you look at their mechanics and maintenance program? it seems like exactly what you are looking for.

York swim has a similar program and practices at Oak Marr and Reston.

If you are trying to not be part of a club swim team- you could try something like Norman swimming, but honestly at ages 13 and 15 I think you would be better off just planning to go to the rec center and let them swim for an hour 1-2 x a week.

Next year we will be ready to transition from club swim with lots of meets and an unhappy coach to more of a maintenance schedule to allow kids rest and flexibility to do other activities but be in shape for summer and HS swim. So maybe practices 2-3 times per week for 13 and 15 year old.

Machine seems too pricey for that ask. Other ideas?

Reston, Herndon, Oakton, Chantilly area.
