As Co-Race Directors of the “Tri” For Acts of Kindness Sprint Triathlon/Duathlon and 5K Run/Walk, Andy Kunsberg and I have had the pleasure and exceedingly good fortune to have On Your Left Fitness and Timing manage and service our event on Saturday, September 17, 2016.  

 The professionalism, expertise, insights and recommendations that Julie and Mark Stark provided brought our event to a new and higher standard which was evidently appreciated by the athletes who took time to find and compliment Andy and me. These compliments rightfully and deservedly belong to Julie and Mark at On Your Left who were always accessible, punctual in their follow-up and dedicated to meeting the requirements of our fundraising efforts.

We eagerly look forward to next September and our continued partnership with On Your Left Fitness and Timing.

 "I was excited with the opportunity to race the SPRING into TRI as my first triathlon in 2015.
 It was a very safe and extremely well organized event, the perfect early season race for the seasoned triathlete to the beginner. Julie and her team makes this event high energy and fun for athletes of all levels.  I would highly recommend adding it to your race calendar."

Tom Armer (Yuma): Just to let you know that I enjoyed your race, very well organized.   We came in from out of town and I did the Duathlon.  Although we love Tucson we never left Oro Valley.  Was impressed with the way the pool swim was managed.  Thanks for allowing us to race and to all the wonderful volunteers.
