Can Runna track rowing workouts?

No. Runna is exclusively a running app. It does not support rowing, erging, or any non-running activity. For erg tracking, you need a dedicated rowing app like Watta.

I row and run — should I use both apps?

Yes. Watta for your erg sessions gives you AI-powered capture and rowing-specific Effort Scores. Runna for your running gives you adaptive training plans. Both sync to Strava if you want a unified activity feed.

Is rowing a good cross-training activity for runners?

Absolutely. Rowing builds cardiovascular fitness with minimal impact stress, strengthens the posterior chain, and develops core stability. Many running coaches prescribe erg sessions as cross-training, especially during injury recovery.

Watta vs Runna: The Erg App vs the Running App

By the Watta Team · Updated March 2026

Quick Verdict

Runna and Watta serve different sports entirely. Runna is an adaptive running plan app that builds personalised training schedules for 5K through marathon distances. Watta is an AI-powered erg workout tracker for indoor rowers. If you row and run, you likely need both. If indoor rowing is your primary training, Watta provides the erg-specific analytics that Runna simply does not offer.

Watta vs Runna: Watta is a free, AI-powered rowing workout tracker purpose-built for erg athletes. It features OCR screen capture, a 0-100 Effort Score (cardiac load 40%, work output 35%, pacing 15%, economy 10%), Karvonen heart rate zones, clubs, squads, and Strava sync. Available on iOS.

Detailed Breakdown

Runna and Watta are not direct competitors — they serve different sports. The comparison is relevant for the many athletes who cross-train between rowing and running. Runna is excellent at what it does: building personalised, adaptive running training plans that respond to your progress. If you are training for a 5K, 10K, half marathon, or marathon, Runna's AI-driven plan adjustments are genuinely useful. However, Runna has zero erg tracking capability. It cannot read a Concept2 screen, it does not understand split time or stroke rate, and it has no concept of rowing-specific metrics like watts per stroke or pacing consistency. If you are a rower who also runs, the ideal setup is Watta for your erg sessions and Runna for your running plan. If indoor rowing is your primary training modality, Watta is the only app in this comparison that can actually capture and analyse your workouts.
