Stop Wasting Your Speed Work: Do These 3 Things First
Speed training is not just about running faster intervals or pushing harder every week. True speed comes from building the right foundation, strengthening the body, and mastering control through sustained efforts. These are the same principles behind the #RedLineProject, a program built to help runners achieve breakthrough performances without burning out.
Build the Floor Before You Raise the Ceiling
If your aerobic base is weak, your speed will always have a limit. Before structured speed work begins, it is important to complete about 12 to 16 weeks of consistent aerobic training. This foundational phase builds the physiological “floor” that supports higher-intensity workouts later on.
When runners skip base training and jump straight into intervals, they miss vital adaptations such as improved capillary density, greater mitochondrial efficiency, and increased stroke volume. These changes enable the body to deliver and use oxygen more effectively during hard efforts (Joyner & Coyle, 2008).
The stronger the aerobic base, the more efficiently the body can handle and sustain intense efforts.
Power Is the Key to Speed
Running alone will not make you as fast as you could be. Speed requires power, and power comes from the muscles, not just the heart and lungs. Strength training is a crucial part of becoming a faster, more efficient runner because it improves running economy and force production.
Incorporating strength exercises such as squats, lunges, plyometrics, and hill sprints builds the musculoskeletal strength needed to convert aerobic capacity into speed. Studies show that adding strength work to an endurance program improves running performance and efficiency without adding unnecessary muscle mass (Blagrove, Howatson, & Hayes, 2018).
Intervals and progression runs may build your endurance engine, but if your body is not strong enough to support that engine, you risk breaking down. It is like installing a Formula 1 engine into a fragile wooden frame. It might start fast, but it will not last long.
Find Your Tempo
Easy runs build endurance, and intervals sharpen speed, but tempo runs are where everything connects. Tempo pace, often described as “comfortably hard,” helps you train in the sweet spot between aerobic and anaerobic effort. It is sometimes called the “Goldilocks zone” of training because it gives the best mix of efficiency, endurance, and speed.
Tempo runs improve your lactate threshold, the pace at which fatigue begins to accumulate faster than it can be cleared. According to Billat et al. (2001), threshold training enhances endurance by teaching the body to sustain faster paces for longer periods.
For runners short on time or looking to build aerobic power effectively, tempo runs offer one of the best returns on training investment. They help you run faster for longer, improve efficiency, and build confidence for race day.
