We are committed to helping swimmers develop life skills through swim lessons. What CRA level should you sign up for?

For returning families:
Lessons - Check your swimmer's iClass profile for their skill stars. If they still have skills to achieve in a level, then register for that level
T3U - If you participated in our T3U program this past year, you are welcome to continue with that program. If you are interested in switching to lessons, sign up for level 3+

For new families:
Lessons - Splash is for 3 year olds, all other swimmers new to CRA should sign up for level 1/2 UNLESS your swimmer has prior competitive swim team experience (not rec team). CRA's lessons focus on building proper technique and our levels are unique to CRA, so their level in a different program has little bearing on their level here at CRA. T3U - Please refer to the link below before signing up for T3U: https://charlesriveraquatics.com/technique-training-tune-up/

CRA staff are constantly evaluating the progress of our swimmers and will adjust class enrollment as we see fit, however, this will not impact the day and time of your enrollment

This one hour high intensity class combines both swim and run workouts. The first 30 min will be a coached swim workout focusing on swim technique, intervals, and endurance. It will be followed by a 30 min high intensity deep water run workout. Water running is a great way to develop and improve aerobic fitness and build strength while minimizing joint stress.

This class is taught by Jen Scalise-Marinofsky, CRA Masters head swim coach. Jen is also an accomplished triathlete competing in the sport for over 30 years and coaching for 17. She is a perennial USAT All American triathlete and has qualified for the Ironman World Championships in Kona 10 times.
