If you want to improve your running speed, it's essential to know which workouts are effective. Threshold training can be a great way to increase both endurance and speed. Intensity: Reps are fast, but not necessarily "hard", because workbouts are relatively short and are followed by relatively long recoveries. Recoveries should be long enough that each run feels no more difficult than the previous run, because the purpose of Reps is to improve speed and economy and you cannot get faster (nor more economical) if you are not running with relaxed form. If it takes 3 minutes recovery between 400m Reps, then that is what is needed. Reducing rest time between individual workbouts does not make for a better workout, in fact it probably makes for a worse workout because the short rests could increase the stress and lead to poor economy. Think of Reps as similar to current 1500m or mile race pace. Running puts stress on the body, and the body reacts to this stress by adapting and becoming stronger. Specific types of stress will bring on specific responses, so you should target your training. Everything that follows is either based on or directly follows these principles. Sometimes there is a balance game that must be played between conflicting principles. Intervals (I) are even more intense. These runs should be around the velocity you can run at VO2 max, or the pace that you could maintain for 10 to 15 minutes. Think about something a little faster than your 5k time. The goal is to bring your body to a state of VO2 max and keep it there. The intervals are of a medium duration (3-5 minutes) with a short recovery period (2-3 minutes).

These six training goals are now the direct purpose behind the training elements presented later in the Formula.There are pretty strict pace suggestions, based on efforts relative to VO2 max. The VDOT calculator adds to the precise nature of this, suggesting very precise paces for each intensity based on a recent performance. As with all base building, you should be increasing your weekly mileage conservatively, increasing by about 10% per week, unless you are an experienced runner. Then you can increase the mileage at a faster rate, just be sure to pay attention to how your legs and body feel. Workouts for this zone should not last more than 90 minutes or 16 miles on long days, but are usually of shorter duration.

Multiplying the total minutes of each workout by corresponding point factors results in training points, Daniels’ new measure of training stress. The VDOT calculator can help you identify the most efficient and effective threshold running workouts tailored towards your individual needs. However, keep in mind that each plan differs, so you may need to adjust it according to your objectives. The transition quality phase is the most stressful and is designed to optimize the components specific to the event being trained for, in this case the marathon.Aerobic capacity defined as the maximal amount of oxygen your body can take in and use during vigorous exercise.

The types of workout for these two to three days of emphasis can vary week to week and phase to phase. A table of recommended workouts for marathon runners is shown in the table below.The season could even attempt to include multiple marathons, but the goal here is to just train for and run a single marathon.
