Track your erg training for HYROX race day

By the Watta Team · Updated 10 August 2026

The 1,000m row is one of the most decisive stations in HYROX. Watta helps you prepare by logging every erg session with AI-powered OCR, tracking your pacing consistency, and building the aerobic base that separates finishers from podium athletes.

Erg App for HYROX Athletes: Watta is a free, AI-powered rowing workout tracker. Snap your erg screen to capture data instantly. Get a 0-100 Effort Score combining cardiac load, work output, pacing, and economy. Track heart rate zones via the Karvonen method. Join clubs and squads to train with your crew.

The Problem

The 1K row can make or break your HYROX time

Many HYROX athletes underestimate the rower station. Going out too fast leads to devastated legs for the remaining stations. Without tracking your erg pacing in training, you are guessing on race day.

Erg-specific training data is scattered

HYROX athletes use multiple tools for running, strength, and functional fitness but rarely have dedicated tracking for their rowing sessions. Erg data ends up in screenshots or forgotten entirely.

No pacing feedback for race simulation

Most fitness apps treat rowing as generic cardio. They do not capture split times, stroke rate, or pacing data that HYROX athletes need to develop a consistent and repeatable 1K row strategy.

How Watta Helps

📷

AI Photo Logging

Snap your Concept2 screen after every rowing session. Watta reads your 1K time, split, stroke rate, and more automatically. Focus on training, not data entry.

⏱️

Pacing Analysis

The Effort Score's pacing component (15% weight) rewards consistent splits. Train yourself to hold an even pace on the rower so you arrive at the next HYROX station ready to perform.

🎿

SkiErg & BikeErg Support

Watta tracks all three Concept2 machines — RowErg, SkiErg, and BikeErg. If your HYROX training includes ski erg work for the SkiErg station, log it all in one place.

How It Works

Snap your erg screen

Take a photo of your PM5 display after your workout. Gallery upload works too.

AI extracts your data

Watta reads every metric — time, split, distance, stroke rate, heart rate, and calories.

Get your Effort Score

A 0-100 score combining cardiac load, work output, pacing, and economy shows exactly how hard you worked.

Frequently Asked Questions

Can Watta track my 1K row times for HYROX training?

Yes. Log every 1,000m row piece by photographing your PM5 screen. Watta extracts your time, split, and stroke rate. Over time, you can see your 1K consistency improve.

Does Watta work with SkiErg as well?

Yes. Watta supports RowErg, SkiErg, and BikeErg. You can log all three machine types, which is useful for HYROX athletes who train across multiple Concept2 stations.

How does the Effort Score help HYROX training?

The Effort Score gives you a 0-100 rating for each rowing session. You can use it to ensure your erg sessions are at the right intensity — hard enough to build fitness without destroying your legs before the rest of your HYROX training.

I am new to rowing. Is Watta still useful for HYROX prep?

Absolutely. Watta captures all the erg data you need to build rowing fitness for HYROX. The OCR logging means you do not need to understand every metric — just snap and train.

Every erg counts.
