Are you a "frequent tri-er"? 

Join LAKESHORE LANDSHARKS (powered by 4 STAR ENDURANCE) - our downtown Chicago-based SWIM-RUN and TRIATHLON "racing club" membership!  Enjoy 20% off your indoor triathlon race registrations all year long + enjoy discounts on gear, training, and receive a piece of bonus team swag at our next event! 

Even if you don't live or train with us in downtown Chicago, you're welcome to join our "RACING CLUB" membership to become part of our team on race days at both our indoor triathlons and outdoor races like the Chicago Triathlon where we have a private TEAM TENT at both the SWIM START and FINISH LINE!

We also offer training programs including swim classes, performance cycling, outdoor tri clinics, open water swims, and our popular 16-week CHICAGO TRIATHLON training program that is open to all ages and ability levels including beginners up to Iron distance!
