Jennifer Conroyd

Chicago-based Jennifer Conroyd is the founder of Fluid Running. With a background as an athlete, Boston Marathoner, and Ironman, Jennifer’s journey into pool fitness began when she tore her calf muscle while training for the Chicago Marathon. Unable to walk, much less run, Jennifer turned to the pool, dedicating herself to deep water running exclusively in the six weeks leading up to the marathon. Her successful completion of the race showcased the amazing benefits of water running. This fueled her desire to share its benefits with everyone, especially with people who are struggling with pain, injury, or conditions which make exercise painful.

Jennifer is certified as an A.C.E personal trainer, a USA Track and Field coach and she holds the Exercise is Medicine credential.  Jennifer is passionate about helping others live healthier, and therefore happier lives.


For me, it has been a lifesaver because it’s the only workout I’m able to do. I recommend it to everybody, at any age. There is no impact.

Gayle Ditchmen

I have Rheumatoid Arthritis, so have not been able to exercise very well.
The first time I got into the pool with it, and I was able to move my body, pain-free, it was a revelation.

As a professional athlete coming back from injury, I kept my mind open and instituted a few new components to my recovery and build back to full health.
