The entire four days of events will be located at Arvesta Sports Complex, at Lake Arvesta Farms, in picturesque South Haven, Michigan.

The festival also includes a celebration of the sport with community events, vendor expos, and opportunities for athletes to connect and represent Age Group Team USA at international championships.

REGISTER

All races take place independently of one another, except the slide-tri and aquathlon.

All times should be considered preliminary.  Days and start time should be relatively firm. Additionally, we have included the average, maximum, and minimum air temperature from the last five years for each event start time.  Information for things like the Team USA Lounge, USAT Foundation VIP Tent, etc. will be added to the schedule at a later date.

Contrary to what you might read on the internet, there is no snow and the lakes are not frozen. The month of May is PR weather in South Haven!
