Of all the different types of training you can do, hills are the most natural way to train on roads and trails. But if it is easy for people living in the hills or mountains to choose between different types of climb, the possibilities are much fewer on the flat, despite the use of overpasses or subway near your home to vary your running. But in both cases, it is impossible to find climbs that are perfectly suited to all needs and that are perfectly even and long enough to do all kinds of training. The possibilities are however endless with the flexibility of a treadmill.
Running on a treadmill allows you to adapt each training session to your needs, varying the percentage of the treadmill's incline, increasing and decreasing the speed of running both uphill and downhill, and extending the distance without being tied to a predefined space. But also by alternating different types of exercise within the same session.
Why running uphill?
Running uphill develops endurance, speed and muscular power, which are important and fundamental characteristics for all distances, from five to ten kilometres, up to half a kilometre and a marathon. To do this, you can use various types of sessions, which allow you to combine several variables, such as the length of the uphill stretches, the number of repetitions to be performed and the inclination of the road. Running uphill develops specific strength, making the leg and foot muscles more powerful. And by increasing the heart rate exponentially, it promotes the heart's ability to pump blood to the muscles and the resulting oxygenation of all the tissues.
How to train uphill
Most runners tend to change the type of foot strike as soon as the road inclines slightly and try to maintain (or even increase) the width of their stride. Nothing could be more wrong, if not done in a controlled manner. By putting your body weight only on the forefoot, you stop running naturally and overload muscles that are not normally recruited so heavily, leading to inevitable injuries.
The first rule is to continue running naturally, bringing your centre of gravity slightly forward, keeping your shoulders straight and shortening your stride. The greater the percentage of incline, the smaller the surface area of the foot that rests, at the same time balanced by an increasing stride frequency.
Running uphill on a treadmill
As mentioned above, running uphill on a treadmill offers advantages that you will not have on a road or path. On a treadmill you can control all the variables of uphill training: distance, speed, incline, variability. It is therefore easy to do a 200-metre repeat training session or a 10-kilometre-long run. Just select your preferred distance and run. Unlike outdoor training, with a treadmill it is also possible to manage the running pace, which can be programmed and controlled throughout the session to know how fast you are running.
How to structure your training
Normally, hill training is carried out by means of long repetitions. There are three possible types of training, each with very precise and different characteristics: short climbs, medium climbs and long climbs. The percentage gradient associated with the distance, the speed of execution (which must always be around 85-90% of your maximum depending on the distance) and the number of runs is also different. Every uphill training session should always be preceded by a 15-20 minute warm-up on the flat, followed by a series of about ten 100/150 meter stretches, always on the flat.
Short climbs can vary in length from 50 to 200 metres and should be run at an incline of between 6 and 10%. The number of repetitions can vary depending on the distance of each individual repetition, from 10/15 times for the shorter ones, with a 60 second recovery, to 8/10 times for the longer ones, with a recovery of up to 2 minutes. This type of training serves to improve running efficiency and therefore to increase leg and foot strength, VO2 Max, cardiovascular system and also running technique.
As for long climbs, it does not make sense to talk about repeats, but better about running uphill over a length of between 4 and 10 kilometres, which must be run with an incline between 4% and 6%. This type of training serves to increase aerobic power by maintaining a continuous and prolonged effort. It is particularly suitable for improving preparation for races from 10 kilometres to the marathon or to get used to races with long climbs.
