“Speed work” may be my least favorite training term because, for most runners, it does not accurately describe the workout in question. Most runners use the term incorrectly because they use it to describe running that, while faster than their normal easy day pace, is not speedy. For example, repetitions – regardless of the distance and rest – done at 5k pace is not speed work. A true speed workout has you running near your maximal, yet most runners refer to track workouts done at 5k pace as “speed work.” Repetitions done at 5k pace, 10k pace or half marathon pace are can’t be considered “speed work” because you’re not running near your maximum. Think about this scenario: What could you run if you had to race across a busy street to save a loved one? The sprinting you’d do to save the loved one is speed work, running that’s at or near maximal. Obviously you couldn’t sustain that sprinting pace for a 5k (or even 400m) so you shouldn’t call you your 10 x 400m workout a speed workout. Instead, refer to workouts done at race pace and be familiar with your race paces for 5k, 10k and half marathon distances. While there is a place for speed development in competitive distance running, most of you will be well served to simply run some strides (100m or so) that are faster than 5k pace a couple of times a week, then run race pace workouts as your training schedule suggests. So take “speed work” out of your vocabulary and simply do workouts at race pace and strides faster than 5k pace.
