Recovery Speed: Measuring Training Effectiveness

Indicators of Good Form and Endurance

The rate and quality of recovery between speed sessions are indicative of an athlete's form and endurance. Developing a recovery strategy that includes a medium pace, rather than just a slow pace, can enhance aerobic capacity and improve overall speed endurance.

Discerning Training: Avoiding Unproductive Workouts

Identifying and Eliminating Inefficient Training

Athletes should be wary of incorporating too many 'gray area' sessions that don't effectively contribute to threshold stimulation or aerobic capacity enhancement. These sessions can lead to stagnation and hinder speed development.

Speed Work: The Strategic Use in Training

Balancing Speed in the Training Regimen

Speed work should be incorporated into training like seasoning in cooking – used judiciously to enhance overall training flavor. Overuse can overwhelm an athlete's ability to adapt, while the right amount can significantly improve functional speed and performance.


Aerobic speed is a critical aspect of an athlete’s toolkit, especially in endurance sports. It's a simple yet profound principle: the faster you can move at an aerobic level, the higher your top-end speed potential. This long-term development of aerobic speed hinges on the disciplined nurturing of the aerobic system through consistent, steady training. Here's a deep dive into the strategies and benefits of enhancing aerobic speed.

Utilising Measured Distances for Aerobic Threshold Testing

Regular Time Trials

Conducting regular time trials, like a 5km run, at your aerobic threshold (AT1) speed is an effective way to track and improve your aerobic speed. This consistent testing helps in gauging progress and making necessary adjustments to your training plan.

Implementing Checkpoints in Long Runs

Incremental Speed Development

Incorporating checkpoints during long runs, where you maintain a consistent heart rate while gradually increasing speed, can significantly boost your aerobic capacity. This method not only enhances your endurance but also builds confidence as you witness improvements in your form and speed.

Measuring Watts at Aerobic Threshold

Power Tracking on the Bike

While many athletes are adept at measuring Functional Threshold Power (FTP), focusing on AT1 power (in watts) can yield substantial benefits. The ability to ride faster at AT1 wattage enhances your overall aerobic engine, a key component in sustaining higher speeds.

Developing Swim-Based Aerobic Speed

Focus on Longer Repetitions

For swimming, prioritize longer repetitions like 400m, 600m, and 800m sets, concentrating on rhythm and relaxation. This approach helps in building sustainable water speed, as tension in the water significantly hinders movement.

Training for Sustainability: Aerobic Speed Across Disciplines

The Importance of Sustainable Training

Training for aerobic speed across different sports disciplines is crucial for sustainable performance. As your aerobic capacity develops, so does your ability to maintain higher training paces over longer periods.

Enhancing Lactate Tolerance
