Row on scenic water routes
in your living room

Row scenic water routes in 3D — right in your browser. Pair a Concept2 PM5 or an FTMS rower when you have one; the Willowbrook demo row needs neither. Open-source, no account, no subscription.

Everything you need

Professional rowing experience,
no gym required

From real Bluetooth hardware integration to rownative.icu route imports, VirtualRow focuses on route selection and live on-water activity.

Scenic Water Routes

Row the bundled Willowbrook River (~5 km), or bring in a real-world course from the rownative.icu catalogue. Here is the whole flow:

  1. Sign in with intervals.icu. No rownative.icu account is needed, and there is nothing to link.
  2. Find a course. Search the rownative.icu catalogue by name from inside VirtualRow, or paste a course ID or a https://rownative.icu/… course link.
  3. Share it. A course opens directly from a link too: ?rownativeCourseId=<id>.
  4. Row it. The course joins the routes list beside the Willowbrook demo, badged rownative.icu with its Established or Provisional status, plus a gates only badge when the course is defined by its start and finish gates rather than a surveyed line.

Compatible rowers (PM5 + FTMS)

Pair a Concept2 PM5 or an FTMS-compatible rower over Web Bluetooth — pick which one you own in the device panel. Live pace, distance, power, stroke rate, calories and splits, no bridge device.

Today's workout from intervals.icu

Sign in with intervals.icu and load the structured workout your coach (or your own plan) has prescribed for today — VirtualRow searches a ±14-day window. A block panel runs the warmup, intervals and recovery while prescribed-vs-actual tiles show pace, power and heart rate against target.

One-click upload to intervals.icu

When you finish a row, the Session Summary offers a single-click FIT upload straight to your intervals.icu activities. Nothing syncs in the background without you — you see every file before it leaves the browser.

Race yourself

Pick any previous session on the same route and watch it row beside you as a ghost boat. A verdict at the finish line says by how much you beat (or missed) your earlier self. It's a solo time-trial — no live multiplayer, no accounts, no servers.

Scales to your hardware

A quick GPU probe picks one of five quality tiers — basic, low, medium, high or extra-high — the first time you row, so a typical laptop stays smooth and a desktop GPU gets the full scene. You can override the pick from the debug panel if the automatic choice is not what you want.

Heart Rate Monitoring

Pair any standard BLE heart rate monitor for live BPM plus average/max heart rate session stats.
