🖥️ Running-X Training Tool: HRmax and Training Zones for Better Running
Training is not just about running more, but run at the right intensity.
Running-X Training Tools were created to help runners and trail runners measure, understand and use heart rate in a scientific way, transforming raw data into a real training strategy.
There are currently two essential tools online:
- HRmax Calculator
- Heart Rate Training Zones Calculator
In the coming months, the Training section will be further expanded with new advanced tools.
📊 What are Running-X Training Tools?
Running-X Training Tools are exercise physiology-based calculators, designed for:
- estimate the maximum heart rate (HRmax)
- to define personalized training zones
- manage loads, intensity and recovery consciously
👉 The goal is train better, reduce the risk of overtraining and improve performance, both on the road and trail running.
Each tool integrates a section Scientific help, which explains not only how to calculate a value, but why it's important.
💓 HRmax Calculator: What it is and why it's essential
What is HRmax?
The Maximum Heart Rate (HRmax) is the maximum number of beats per minute that the heart can reach during intense exercise.
It's the main reference point for:
- calculate training zones
- control the intensity of efforts
- schedule loads and recovery
An incorrect HRmax leads to the wrong zones → ineffective training.
How the Running-X HRmax Calculator Works
The HRmax Calculator Running-X allows you to estimate your HRmax using the most accredited formulas in literature, including:
- Haskell & Fox (1970) – quick estimate (220 − age)
- Cerretelli (1988) – suitable for endurance sports
- Tanaka (2001) – ideal for adults and over 40s
- Gellish (2007) – one of the most accurate
- Gulati (2010) – specifically for women
- Because (2013) – based on recent studies
👉 The tool shows more estimates, allowing you to compare them and choose the one that best suits your running profile.
📌 Alternatively, Running-X also explains the direct field tests (maximal tests, Conconi, uphill tests), more precise but must be performed with care.
⏱️ Heart Rate Training Zones Calculator: Train in the Right Zones
Why training zones are crucial
The heart rate zones allow you to:
- stimulate different energy systems
- improve endurance, threshold and VO₂max
- avoid overly intense workouts on the wrong days
- better manage recovery and fatigue
In trail running, where pace and gradient vary continuously, heart rate is often more reliable than speed.
What does the Training Zones Calculator calculate?
The Heart Rate Training Zones Calculator Running-X allows you to define zones with different scientific approaches:
- Percentage of HRmax (simple and widespread method)
- Method Karvonen (more precise, includes resting HR)
- Lactate Threshold Method (LTHR) for advanced athletes
- RPE – Perceived Exertion to train even without a heart rate monitor
👉 You can choose between classic areas, alternative or customize them manually.

The 5 Heart Rate Zones in Running
In simplified terms, the main areas are:
- Zone 1 – Recovery: regeneration and health
- Zone 2 – Endurance: aerobic base and fat utilization
- Zone 3 – Time: improved endurance
- Zone 4 – Threshold: lactate management
- Zone 5 – VO₂max: speed and power
A good training program includes a lot of work in Zone 1–2 and targeted stimuli in the higher areas.
💡 The added value of Running-X Training Tools
✔ Based on real physiological models
✔ Suitable for runner e trail runner
✔ Can also be used from mobile, on the field
✔ With Integrated scientific help to really understand what you're doing
Running-X doesn't just tell you how often should you train?, it teaches you why.
🔥 Training on Running-X is just beginning
The Training Tools represent the first step towards an increasingly complete platform, where training, health and performance they talk to each other.
