Understanding Threshold Training in Cycling

Threshold training is a cornerstone of cycling performance improvement. It focuses on enhancing a cyclist’s ability to sustain high-intensity efforts over time. The idea is to train near the cyclist’s lactate threshold. This is the point where lactate accumulates in the muscles faster than it can be removed.

Knowing your threshold is crucial. It helps tailor your training sessions to achieve the best results. Cyclists often measure this through Functional Threshold Power (FTP). FTP represents the maximum power a cyclist can sustain for approximately one hour. Many cyclists use devices like power meters to measure FTP on the road or in controlled environments.

The Science Behind Threshold Training

The human body relies on two primary systems for energy during exercise: aerobic and anaerobic. The aerobic system uses oxygen, while the anaerobic system works without it. At lower intensities, metabolism is primarily aerobic. As intensity increases, the anaerobic system contributes more.

Lactate threshold marks the shift towards more significant anaerobic energy supply. When exercising at or just below this threshold, athletes can maintain effort for longer durations. Going significantly above this point leads to quicker fatigue and a need for recovery.

Benefits of Threshold Training

• Improved aerobic capacity: Training near threshold intensifies aerobic ability.
• Increased endurance: Cyclists can maintain higher powers over extended periods.
• Better pacing strategies: Understanding limits aids in pacing during races or long rides.
• Enhanced lactate clearance: Regular training helps the body remove lactate efficiently.

How to Determine Your FTP

Assessing your FTP provides a benchmark for threshold training. A common method is the 20-minute test. After a comprehensive warm-up, cyclists ride at maximum sustainable effort for 20 minutes. The power average during this time is multiplied by 0.95 to estimate FTP.

More accurate results come from professional tests in laboratory settings, involving gas analysis and blood lactate measurements. However, at-home FTP tests are sufficient for most cyclists. Regular retesting is recommended as fitness levels change.

Structuring Threshold Training Sessions

A well-rounded training plan includes threshold sessions. These workouts typically feature intervals at or near FTP. Here’s a basic structure:

• Warm-up: 10-20 minutes at an easy pace to prepare muscles.
• Threshold intervals: Several sets of high-intensity efforts with recovery periods.
• Cool-down: 10-15 minutes of light cycling to aid recovery.

For example, a workout could involve 4×10-minute intervals at FTP with 5-minute recovery between each. It’s crucial not to overreach. Train at your assessed threshold, gradually increasing duration or intensity over weeks.

Monitoring Progress

Tracking improvements is essential for motivation and progression. Use power meters or heart rate monitors to evaluate performance. Notice changes in average power during intervals over time. As FTP increases, adjust training loads accordingly.

Keep detailed records of each session. Log power outputs, how you felt during efforts, and recovery quality. This helps to fine-tune future sessions and recognize patterns in performance.

Common Challenges and Solutions

Threshold training can be demanding. Many cyclists face challenges like fatigue and motivation loss. It’s important to balance intensity with ample recovery. Include rest days and lighter weeks in training plans.

Nutrition plays a vital role. Fuel workouts with carbohydrates for energy and proteins for recovery. Hydration before, during, and after sessions is equally important. Adjust food intake based on workout intensity and duration.

Equipment for Threshold Training

Investing in good equipment can enhance training. Power meters offer precise data essential for training at the correct intensity. Smart trainers provide consistent conditions for indoor sessions, eliminating variables like weather.

Heart rate monitors offer additional insights, although heart rate can fluctuate due to various factors like stress or temperature. Use heart rate data alongside power for a comprehensive view.

Incorporating Threshold Training into a Broader Plan

While essential, threshold training is only one part of a complete cycling program. It should be combined with other training types, like endurance rides and high-intensity intervals. A periodized approach often yields the best results, adjusting volume and intensity throughout different training phases.

Mixing threshold sessions with varied workouts prevents monotony and overuse injuries. It also addresses different aspects of cycling fitness, making riders more well-rounded athletes.

Threshold Training: A Key to Cycling Success

Threshold training helps bridge the gap between everyday riding and competitive performance. Cyclists, whether novice or experienced, can benefit from structured threshold sessions. The balance between hard work and adequate recovery drives improvement.

Focusing on the science behind training, staying consistent, and adjusting according to progress are all part of this journey. As the cycling community grows more tech-savvy, threshold training continues to evolve, offering endless opportunities for advancement.
