About
Runalyze is a manufacturer-independent analysis platform built for endurance athletes who want to make data-driven decisions about their training. At its core, Runalyze estimates your effective VO2max — a scientifically validated metric for maximal oxygen uptake — and uses it alongside a unique marathon shape calculation to deliver up-to-date race predictions for distances from 3K to ultra-marathons. The platform models both acute and chronic training load using heart rate data, enabling athletes to understand their current fitness state and avoid overtraining. A dedicated equipment tracker ensures you never miss replacing worn-out running shoes or bike components. Runalyze offers rich visual statistics including trend analyses, boxplots, dynamic histograms, and performance curves (power, heart rate, and pace) for the last 90 days. Athletes can compare competition results by age grade, effective VO2max, or speed, and dive deep into historical training data via progression graphs and ANOVA analysis. Additional features include hill and climb categorization (mirroring Tour de France categories), activity heatmaps, calendar and grid views, and a poster generator for sharing training highlights on social media. Premium subscribers unlock best-segment analysis, quality session reviews, moving average mileage tracking, a tiles counter, and historic HRV value plots. Runalyze is free to start, privacy-first by default (your data is never sold), and compatible with a wide ecosystem of GPS devices and fitness apps.
Key Features
- VO2max Estimation & Race Prediction: Calculates your effective VO2max from activity data and uses it alongside a marathon shape model to predict race times across distances from 3K to ultra-marathon.
- Training Load Monitoring: Models acute and chronic training load from heart rate data so athletes can monitor fatigue, fitness, and readiness at a glance.
- Performance Curves: Visualizes power, heart rate, and pace curves over the last 90 days, allowing athletes to identify performance trends and peak efforts.
- Equipment Tracking: Tracks usage of running shoes, bike parts, and other gear so you know exactly when equipment needs to be replaced.
- Activity Visualizations & Poster Generator: Generates heatmaps, calendar views, and shareable training posters from your complete activity history, including climb categorization inspired by Tour de France ratings.
Use Cases
- A marathon runner uses Runalyze to monitor acute and chronic training load and ensure they peak on race day without overtraining.
- A triathlete tracks equipment usage across running shoes and bike components to schedule timely replacements before gear failure.
- A competitive runner compares historical race results by age grade and effective VO2max to identify their strongest disciplines and untapped potential.
- A fitness enthusiast generates an annual training heatmap poster to celebrate a year of consistent workouts and share it on social media.
- A cycling coach uses Runalyze's hill and climb categorization to evaluate riders' performances on categorized climbs throughout the season.
Pros
- Privacy-First Design: All data is private by default and never sold, giving athletes full control over what they share.
- Manufacturer-Independent: Works with a wide range of GPS devices and fitness apps, so athletes are not locked into a single ecosystem.
- Scientifically-Grounded Metrics: Uses validated sports science models for VO2max, training load, and race prediction rather than generic estimates.
- Free Tier Available: Core analysis features are accessible at no cost, making professional-grade training analytics available to all athletes.
Cons
- Niche Use Case: Runalyze is built exclusively for endurance sports, limiting its appeal to athletes outside running and cycling.
- Advanced Features Behind Paywall: Power features like best segments, quality session analysis, HRV history, and the poster generator require a Premium subscription.
- Steep Learning Curve: The depth of metrics and analytics can be overwhelming for casual athletes unfamiliar with sports science terminology.

Is Runalyze free to use?
Yes, Runalyze offers a free account that includes core training analysis features such as VO2max estimation, race prediction, training load, and visual statistics. A Premium tier unlocks additional features like the poster generator, best segments, HRV history, and moving average mileage.
What devices and apps is Runalyze compatible with?
Runalyze is manufacturer-independent and supports a broad range of GPS devices and fitness platforms. You can check the full list of compatible devices and apps on their website.
How does Runalyze calculate VO2max?
Runalyze estimates your effective VO2max using data from your recorded activities, including heart rate and pace information. This value is correlated with your maximal running performance and is continuously updated as you log more workouts.
Is my training data private on Runalyze?
Yes. Runalyze is privacy-first — all default settings are set to private, your data is never sold, and you have full control over what information is shared publicly.
Can I use Runalyze for sports other than running?
Runalyze supports multiple endurance disciplines including cycling and other activities where GPS and heart rate data are available. Features like climb categorization are especially relevant for cyclists.
