The world of ultrarunning demands athletes to push beyond their perceived limits. In this challenging discipline, trail and ultrarunners engage in meticulous training to measure and understand exercise intensity. While technology has significantly influenced the training methods across various endurance sports, including heart rate monitoring, there’s a growing recognition among experts and coaches of the efficacy of Rate of Perceived Exertion (RPE).

The Role of Heart Rate Monitoring

The technological evolution in sports training has been remarkable, providing valuable biofeedback to athletes and coaches. Heart rate monitoring, in particular, has been a cornerstone for assessing an athlete’s exertion, offering insights into exercise intensity, aerobic fitness, training zones, and overall cardiovascular health. This method involves observing an athlete’s heart rate during training sessions and recovery periods, enabling them to fine-tune their training regimens based on this data.

Modern training programs have embraced the five-zone model, a fundamental framework applicable to athletes of all skill levels. This model empowers athletes and coaches to customize workouts according to specific physiological adaptations, proving invaluable for improving endurance sports performance. Zone 2 training, in particular, has gained popularity for fostering aerobic fitness and endurance. In addition to Zones 1 and 2, Zones 4 and 5 cater to higher, less sustainable efforts, crucial for lactate threshold and VO2 max refinement.

Despite the advantages, heart rate monitoring has its limitations. In particular, wrist-based heart rate monitors often use photoplethysmography (PPG), measuring changes in blood volume to estimate heart rate. While it provides convenience, this technology can introduce inaccuracies. For precise measurements, chest strap monitors are preferred but can be cumbersome for trailers and ultrarunners seeking simplicity during their activities.

Balancing Act with Rate of Perceived Exertion

The overreliance on heart rate zones may lead athletes to become hyper-focused on minute data points, neglecting their overall physiological responses to exercise. Awareness of these limitations is essential. Furthermore, for trail and ultrarunners, the technology’s practicality can be questionable.

Cycling introduced power meters in the 1980s, a game-changing innovation for measuring mechanical force applied to the pedals. This precise measurement transformed training and pacing strategies in cycling. However, the application of power meters is more complex for trail and ultrarunners, as they estimate power-related metrics based on biomechanical factors, which can be challenging to implement on variable terrain.

The Benefits of Rate of Perceived Exertion (RPE)

Amidst these technological advancements, the Rate of Perceived Exertion (RPE) stands as an invaluable tool. Developed by Swedish psychologist Gunnar Borg in the mid-20th century, RPE is a subjective measure of one’s perception of effort during physical activity. It fosters a deep understanding of one’s body, leading to more effective training and pacing strategies. RPE is highly adaptable and well-suited for the ever-changing nature of trail and ultrarunning, where terrain and weather can shift rapidly. This approach empowers athletes to tune into their bodies and exercise confidence in their instincts. Best of all, it requires no additional equipment or technology, making it a simple and pragmatic tool for trail and ultrarunning enthusiasts.
