Runalyze

Runalyze is a German training analysis platform for runners and triathletes that goes deeper than Strava's feed ever will: effective VO2max estimation, marathon shape tracking, race-time prognosis, and TRIMP-based training load and fatigue metrics turn raw workouts into an actual training picture.

Data flows in from Garmin and other devices or file uploads, and comes out as detailed pace, heart rate, and elevation analysis across seasons. The core service is free and stays free, with a Supporter tier removing ads and a Premium tier around 6 euros per month adding advanced tools. There is no social pressure engine, no segments to chase, just your physiology over time.

Key features:

• Effective VO2max estimated from every run automatically
• Race-time prognosis projecting current shape onto race distances
• Training load metrics with TRIMP, fatigue, and form tracking
• Garmin import plus standard file formats from any device
• Season-level analysis of pace, heart rate, and elevation trends
• Free core service with all main features, no paywall creep
• Community-driven roadmap through a public ideas portal

Runalyze is operated by Runalyze GmbH in Germany, built from Kaiserslautern and Kiel, and processes athlete data under GDPR. Your training history stays with a small German company rather than feeding a US social network's engagement metrics.

Ideal for data-driven runners who care more about their VO2max trend than their kudos count.
