The SpeedCoach SUP 2 is the only product on the market with a SUP-specific calorie equation. No other performance monitor offers an equation based on the precise motions of stand-up paddling.The experts at NK have partnered with researchers from the University of Montana to bring SUP paddlers an equation that takes into account three distinct SUP profiles based on different levels of paddling techniques and energy expenditure based on oxygen consumption.

The NK SUP-Specific Calorie equation gives you a real-time accurate answer to the question, "How many calories did I burn during that SUP workout? Learn More »

Reviews & Testimonials

  • Renick W

    “I use the SUP SpeedCoach all the time. The first one was great, and the second one is even better! Nielsen-Kellerman kept all the reasons I loved the first edition and added great new features. You can now program in intervals and upload your data after your workout! As always, it has fast feedback per stroke, the big screen to actually read numbers and speed as you paddle, and the light for night/morning paddles. I could go on and on about other things that make it great, but I'll keep it short. The SpeedCoach is hands-down a very solid piece of equipment, and if you're serious about paddling and improving, it should be a tool in your arsenal. You'll be hard-pressed to find a better GPS out there.”

  • Joel & Coli

    J “I really enjoy using the Speedcoach SUP 2 for training and racing with Coli. She enjoys checking our speeds to make sure we're on track while we're tandem SUP training and racing. Best of all is when she glances at the display, notices improvement, and lets out a soundquake of excitement mid-paddle stroke!”

    C "I like knowing what speeds we're going. The Speedcoach keeps me on track, and we don't have to slow down like we used to when daddy used to check his watch."

  • Chuck G

    “Thanks, NK, for the technology to be able to read the data while paddling to find better currents during a race”

  • Distressed Mullet

    The first generation SpeedCoach SUP was great, and NK solicited a lot of feedback for the new version. Here is where it gets really crazy…they actually listened. The bottom line is NK hit a home run with the new version.”
