  • Masters Swimming Naperville – October 2 – October 27

    ET Masters is a weekly adult swimming program designed for triathlon and fitness swimmers. ET Swim coaches will provide structured workouts and stroke improvement tips at each group session.


    Program pricing is reduced each week so that swimmers only pay for the remaining weeks of the session when they do sign up.


    Swimmers have the option of one day a week, two days a week, or just a single-day drop-in registration!


    Dates:   October 2 – October 27 (4 weeks)


    See tabs below for days/times/location and program info


    Is Masters only for Advanced swimmers? 

    Actually, the word Masters does not have anything to do with your level of swimming.  It’s a term that USA Swimming uses to describe “adult” swimmers vs “youth” swimmers.  Our program is filled with intermediate and advanced swimmers of all speeds, abilities, experience levels.  If you can swim laps freestyle in the pool and do at least a total of 1000 yards with many rest stops over the hour-long session, you’ll be fine.  If you’re still learning to swim and struggle to get across the pool for a lap or two, our Swim 101 Learn to Swim or private lessons are the way to go.



  • Swim 101 – Learn to Swim – October

    ET Swim 101 is the perfect class to bridge the gap between ET private swim lessons and ET Masters. Participants should be able to swim one length of the pool without stopping. If you can’t, please consider a private swim lesson with us!


    ET Swim 101 provides adult learn-to-swim instruction and practice in a small class format. Participants will be introduced to lap swimming with the goal of eventually joining the ET Masters Swim program.

    • Develop proper kicking and breathing technique
    • Improve stroke efficiency
    • Learn and practice the common swim stroke improvement drills
    • Build endurance


    Whether you want to start a lap swimming program or do a triathlon, ET Swim 101 can help you reach your goal. This program is coached by Joe LoPresto and Christa Krause.
