Understanding Cardio Zones
So, what are cardio training zones? Cardio zones refer to different intensity levels of exercise, each targeting specific energy systems based on heart rate or perceived exertion. These zones are determined as a percentage of your maximum heart rate (MHR) – which can easily be estimated using the formula:[i]
220 – your age = max heart rate
There are different ways to categorize training zones, with common models using either 3 or 5 zones. Physiological markers like VO2 max – the mount of oxygen your body can use during intense activity – help define these zones.i Essentially, the higher your heart rate, the higher the heart rate zone you’re in, meaning your body is working harder to sustain the effort.
Let’s look at the 5 different heart rate zones:ii
- Zone 1 (warm-up): 50-65% of VO2 Max or 60-72% of Max Heart Rate
- Zone 2 (aerobic, endurance, base, light effort): 66-80% of VO2 Max or 72-82% of Max Heart Rate
- Zone 3 (tempo, threshold, moderate cardio): 81-87% of VO2 Max or 82-87% of Max Heart Rate
- Zone 4 (lactate threshold, hard effort): 88-93% of VO2 Max or 88-92% of Max Heart Rate
- Zone 5 (anaerobic, peak, maximum effort): 94-100% of VO2 Max or 93-100% of Max Heart Rate
Benefits of Cardio Zone Training
Let’s talk about how the different zones come into play when on a hike.
Zone 2 training can improve aerobic capacity when it comes to long hikes. This zone is also considered our fat burning zone and is the foundation of endurance. In this zone, our body uses fat for fuel, which is crucial during a long hike where energy conservation is key. Hikers who train in Zone 2 can maintain steady paces for hours with less fatigue, making uphill treks and multi-day hikes feel more manageable.i
Training zones 3 to 4 will increase your stamina and push through discomfort for those steep climbs. This zone will train your body to clear lactic acid efficiently, reducing muscle fatigue and helping you hike at a brisk pace without burning out.ii Training in these zones helps prepare you for those high-effort moments before fatigue sets in, making it easier to tackle challenging terrain.
While zone 5 is not commonly used when training for a hike, it can be helpful when approaching sudden steep inclines, scrambling over rocks, or carrying extra weight when needed. This zone enhances your power, agility, and fast-recovery response.
Training in all zones will help you build endurance, strength, and resilience, ensuring that you are able to handle anything that the trail throws at you. Off the trail, this translates to better heart health, improved energy levels, and greater overall fitness, making daily activities—like climbing stairs or keeping up with an active lifestyle—effortless.
How to Monitor Your Heart Rate
Now that we’ve gone over which heart rate zones to train in when preparing for your hike, you might be asking yourself, how do I know if I’m in the right zone?
Wearable technology such as heart rate monitors, smartwatches, and fitness trackers, has revolutionized cardio zone training by providing real-time data on heart rate, exertion levels, and overall performance. These devices help hikers stay within their target heart rate zones, ensuring they train efficiently without overexertion or undertraining.
By tracking metrics like VO2 max, recovery time, and calorie burn, wearables offer valuable insights that allow hikers to optimize their endurance, improve stamina, and monitor progress over time. Whether on the trail or in training, wearable tech makes it easier than ever to fine-tune workouts and maximize performance.
If wearable tech is not your thing or if you prefer a more hands-on approach, manually checking your pulse is a simple and effective way to monitor heart rate during cardio zone training.
To do this, pause briefly and place two fingers (not your thumb) on your wrist (radial artery) or neck (carotid artery). Count the beats for 15 seconds, then multiply by four to estimate your beats per minute (BPM).iii
Comparing this number to your target heart rate zone ensures you’re training at the right intensity. While not as precise as wearable technology, manual pulse checks are a great backup method, especially in remote areas where devices may lose battery or signal.
Common Mistakes to Avoid When Cardio Zone Training
One of the most common mistakes in cardio zone training is ignoring rest and recovery, which can lead to burnout, fatigue, and even injury. Many hikers focus on pushing harder without allowing their bodies time to rebuild, but recovery days and lower-intensity Zone 1 training are just as important for endurance and muscle repair.
Another mistake is overemphasizing a single zone, such as always training in Zone 3 for moderate effort without incorporating lower or higher intensities. This can limit progress by neglecting endurance-building in Zone 2 or power development in Zones 4 and 5.
To avoid these pitfalls, hikers should follow a balanced training plan that includes a mix of all zones, along with proper rest, to ensure steady improvement and long-term performance gains.
Conclusion: Elevate your Hiking with Cardio Zone Training
So, all of this is to say, cardio zone training is a game-changer for hikers, offering a structured, efficient way to build endurance, improve stamina, and tackle challenging terrain with confidence. By training across different heart rate zones, you can hike longer with less fatigue, recover faster, and develop the strength needed for steep climbs and technical trails.
Monitoring your heart rate – whether through wearable technology or manual pulse checks – ensures that you’re training at the right intensity to maximize results while avoiding burnout. Incorporating cardio zone training into your routine will not only enhance your hiking performance but also improve overall cardiovascular health and energy levels in daily life. So, if you’re ready to take your hiking to the next level, start training smarter, listen to your heart, and experience the difference on the trail!
