Like the recipe of your favorite dish, your runcoach training plan combines many difference types of ingredients. Each of these ingredients are important, even as some of them come in large quantities and some are just a pinch of salt on top of a mound of flour in the bowl.
Your runcoach pace chart provides a wide array of paces for various types of workouts prescribed on your individualized schedule,. Your marathon, maintenance, 80% and half marathon paces are paces your body should be able to handle for long durations – paces at which your cardiovascular system can keep up with the oxygen demand of your muscles for extended periods of time. Even though you may not be out of breath during this type of running, your muscles are building more extensive and efficient pathways for oxygen and energy delivery. In addition, your mind is preparing for the lengthy race task ahead. If you are using a heart rate monitor, this running is done somewhere in the range of 65-85% of your maximum.
While some “Pace Runs” on your schedule might be prescribed at slower paces, “threshold” running is designed to challenge you at a comfortably hard level. This pace should be sustainable for a shorter period of time, say 20-25 minutes, but should not feel easy to continue much beyond that duration. It should also not feel hard after just a few minutes of running. This area of pacing helps to challenge your body to become more efficient with handling a steadily accumulating blood lactate level (something you will have to do in races shorter than a half marathon). Threshold workouts are ideally executed at about 88-92% of your maximum heart rate.
Crossing the “threshold” literally and figuratively, leads us to paces that can only be performed for shorter, more challenging periods of time. Balancing intervals or repetitions with just enough rest or active recovery allows an athletes to spend a significant cumulative period of time at a quick pace and high heart rate, conditioning the body and mind to operate effectively and efficiently at that level of demand, which is ideally in the mid to high 90s of maximum heart rate percentage. If one ran a series of 800m intervals at 4:00 with 90 seconds recovery, each successive interval would see the athlete’s heart rate shoot up more and more quickly within the 4:00, but ideally not so quickly that the athlete could not complete the interval at the prescribed pace. This effect may result in the first couple intervals of a workout feeling slightly easier than anticipated, tempting the athlete to run faster than the prescribed paces. While this may seem logical – to run harder initially and shoot the heart rate to the moon on the first interval – the workout is designed to create its effect by the end of the session. What may seem like a comfortable pace on the first interval turns out to be a misguided assessment as the athlete slows down precipitously at the end or requires way more rest than assigned.
Some athletes may wonder why an 800m or 1500m pace might even be assigned to them as they train for a half or full marathon. Although the bulk of an endurance race training schedule includes work preparing for the paces, energy efficiency, heart rate demand, and mental effort of the longer races, workouts prescribed with some quicker paces allow an athlete to work on running economy. Workouts or even strides on your schedule at 800m or 1500m pace provide a valuable opportunity for athletes to challenge the fundamentals of their running stride, to teach their legs to have a bit more range of motion in the stride, to strengthen their feet to push off the ground more effectively, quickly, and with strength. Although they may seem inconsequential in the larger picture, even small improvements in this area can result in large gains considering how many thousands of strides we take during the course of our general training.
While it is normal and natural to feel more at home with one type of workout over another, avoid the inclination to slough off the types of workouts that seem unfamiliar or not in your wheelhouse. Each of the paces prescribed in your schedule has a purpose. Commit to executing each workout with mindfulness and a sense of purpose. This is your best chance of turning out a race day “dish” you’ll remember for years.
