If you only cycle for fun and relaxation, you don't need a power meter or any technology on your bike that goes beyond pure drive mechanics. However, if you want to train specifically or want to better understand cycling in general and your own body in particular, it is an ingenious tool. Cycling is the best-researched endurance sport - because of the comprehensive data collected with power meters. TOUR shows four reasons why it is worth buying a power meter.

1. power meter: Understanding what you are doing

For the first few rides with a power meter, you could also simply tape off the computer and collect data to look at afterwards. The recording reveals how intense the ride was and where you stand in terms of performance. In most cases, the power curve reflects the terrain. More effort is invested uphill, less on the flat. Performance usually decreases over the duration of the effort. The performance peaks are much higher than the average performance. From basic speed to sprinting, the power output can increase tenfold; the human motor is very dynamic. If you look at the data and compare it with the riding experience, you can see what hurts: particularly steep climbs that push your legs into the red zone. Comparing power data with heart rate and other data provides further insight.



2. testing, training zones, targeted training

You can test yourself with a short time trial and define your training zones (FTP test or similar). You can then train very specifically in certain areas to maximise the benefits of your training. However, the power meter does not provide training information; it only displays the power output. Targeted training therefore also requires a training plan based on power values. No coach today works with athletes who do not use a power meter. Progress in performance is simply much easier to measure.

3. pacing in competition and training

The power meter is a great tool for setting the right pace. You get an immediate indication of whether the power you are applying on a climb is sustainable or not. In contrast to body feeling or riding by pulse, there is no delay between the increase in speed and the display; the power reacts immediately. This can be used in competitions to choose the right pace right from the start. In marathons in particular, but also in training, it helps not to mix up all the training zones.

4. understanding cycling

If you analyse race data or group rides, you can quickly see what caused you to be left behind or to master situations well. From the power data, you can see at what load you lose the connection. This gives you an indication of which skills need to be trained. But you can also see positive effects such as saving energy in the slipstream. Also suitable for material tests Powermeter. Because the goal is always to drive faster with less power.
