Marathon - 25 euro

Half-Marathon - 25 euro

5000m - 20 euro

2000m - 20 euro

500m - 15 euro

The events are the Marathon, Half-Marathon, the 5000m, the 2000m and the 500m (sprint). Team of 4 can also participate in all events, except the 500m.

ErgZone is the ONLY mobile app that allows coaches and athletes to program a custom ergometer workouts. I also invite athletes and teams to train virtually using the same platform. The application also allows results to be ranked globally via an online leaderboard, and racing LIVE (head-to-head).

For 2026, Teams of 4 men or 4 women can join. The reasoning is to create a collective LIVE sloep rowing experience in a virtual environment. At the moment, individual results are averaged to create a boat position (rank) amongst other boats at the end of the LIVE race.

The software team is currently developing the ability for individual results to be averaged LIVE during head-to-head racing; effectively creating boat vs. boat LIVE action.

Online documentation is accessible. Please inform info@robox.fitness so the development team is aware.

Good question. To become comfortable working in and connecting your rowing machine with ErgZone takes a little practice. Believe me, just ask any member of my classes! If you choose to train with us (starting in January) you will have plenty of time to become comfortable.

ErgZone has suggested creating formal practice sessions along the way; where registrants will connect together and learn together.

Training for a row marathon using heart rate zones (with an approximate MHR from the 500m base) and limited time (2 x 45 to 60-minute rows per week) provides several specific and strategic benefits—especially for beginners or busy individuals.

Heart rate zone training with a time-efficient structure helps beginners:

• Build endurance smartly
• Minimize injury
• Maximize performance gains
• Develop discipline for row marathon pacing

There will be no refunds. Please know this upfront. We count on your entry fee to support this event and all its associated costs.

Row submissions and leaderboards open at 0900 CET January 18th 2026, and end in late February 2026. Row submissions during the leaderboard open will be ranked along with the final submissions.

Yes! It's definitely possible. Although we have limited spaces available for 2026, please contact me as soon as possible to make arrangements.

If you are rowing on machine that does not interface with ErgZone, or on a Concept2 RowErg with a PM older that the PM5, you can still compete! You won't be able to connect to live racing on ErgZone, but you can manually submit your score on the ErgZone app. It will count in our official results and rankings.

‍

We are still working on this. Locally in Terschelling, we are trying to find budget to provide participant medallions and Terschelling flag headbands! Concept2 also provides a certificate for those who submit their race via the Concept2 logbook.

This is my first year organizing the Rondsje Om. I hope to get better at this in the next few years.. so you get better stuff!

Rowers  IN OTHER TIME ZONES may compete independently at their local time while the leaderboards are open.
