JSET works by understanding the relationship between weekly mileage and weekly pace, and combining these two factors into a measure of training load. JSET builds your training program slightly differently depending on what your goal is.
If your goal is to improve your fitness and become a better runner then JSET assesses your recent training and sets a target at the start of the week that is a little higher than the training load you have recently managed. Each week JSET repeats this process. In this way JSET adapts to how well your training has been going. For example, if you are progressing quickly JSET ‘learns’ this, and pushes you a little harder than it would for someone who has had some time off running.
If you have a specific race goal, JSET quantifies your fitness using data from recent runs, and compares that to the required fitness level for your target race time. Knowing the difference between where you are and where you want to be, JSET sets out the required training load for each week between today and race day. This gives you a clear roadmap that will allow you to gain the fitness required to achieve your race goal.
By only prescribing training load each week, JSET allows you to tailor your training to your preferences. This means that you are able to run:
- Short and sharp
- Long and slow
- Any combination of the two – as long as you meet the required training load.
In practice, this means that the further you run each week, the slower your average pace can be in order to achieve any given race time. Importantly JSET won’t dictate how you should run these miles, it’s simply about the total training load. Realising that it doesn’t matter how you achieve your miles is a game-changer. There’s no one ‘right’ way to train.
