The 29th Annual TINMAN starts with 5K Walk/Run around the beautiful CSUSB campus.  Triathletes continue with a bike ride, approximately 9 miles, featuring a challenging grade into Devil's Canyon topped off with 100 yards in the pool, topped off with a sprint to the finish line.  Relay teams are welcome!  Medals 3 deep in each category, plus every finisher receives a medal.  (All kids 4-12 receive medals.)

Proceeds benefit the many San Bernardino Sunset Rotary Club projects from local scholarships, feeding the hungry and homeless to stopping POLIO NOW.

One of Southern California's premiere athletic events, The "Original" TINMAN has something for everyone:

Triathletes, 5K Runners and Walkers, Disabled Athletes, Tri-Teams, and of course, Kids and Tiny Tots.


Hosted on the beautiful campus of Cal State San Bernardino, join us for a morning of great competition, prizes, refreshments, vendors, and FUN!
