About This Activity

Due to COVID-19, changes have been made to this year's CAST Mighty North Fork Triathlon.

Participate in a virtual duathlon: Run 2 miles, Bike: 7 miles, Run: 5k.  You will have one week, May 25th – May 31st, to complete this and then would send your results to us.  After you upload your results you will receive this year’s finisher medal, t-shirt, goodie bag and 30% off of next year’s race.  In addition, you will receive a custom pair of socks and a custom visor. 

All finishers will be entered into a post race raffle to win: a $50 Runner’s Edge Gift Certificate, a Bicycle Makeover Spread the Love front door decal and a sprint race passport for the 2021 season.


This is one of the best first timer courses with a calm Peconic Bay swim, a mostly flat, scenic 7 mile bike and an equally scenic 3.5 mile run. Held in the heart of Long Island’s wine region, this event has something for both athletes and spectators alike. 

Swim: 500 meters, Bike: 7 miles, Run: 3.5 miles

Start Time: 6:50am
