Our exclusive TRI – One program was launched many years ago when athletes raced as part of their training, rewarded themselves for all the training they were doing and to gain all that important race day experience you cannot simulate.   As the multi-sport community has evolved to the opposite now we are bringing back the program.  It is really simple, you need more open water swim training? Great, cmon out and get it with our lifeguards and courses.  Want to get a nice hard time trial on the bike in?  Cmon out and race on our course.  Need to get a run in and want to do so with aid stations?  Cmon out and join other runners.  

Each TRI – One will have a designated start time, you will simply head to the TRI – One start flag for the discipline you choose, line up, and when the clock strikes and the horn sounds you are off.  With our events, time trial swim starts now you will line up accordingly.  Or if you want to take the Kayak or SUP out for a nice paddle with others where offered.

The cost for these is a flat $30.  For that, you get a finisher’s medal and access to the post-race food tent.  You may purchase a shirt for $10.  

You can register online or onsite.  If onsite it is cash only!
