It's that time again: the 2025 time change to winter time will take place on Saturday night. What does this mean for your cycling training and performance routine? We explain how you can best prepare for the clock change, why your biorhythm can change when cycling - and give practical tips for bike athletes.

The time change refers to setting the clock forward or back by one hour. In Germany, the time is changed twice a year - in spring and autumn.

Why is the clock set back from 3 to 2?

Germany has had summer and winter time - also known as CEST (Central European Summer Time) and CET (Central European Time - also known colloquially as standard time) - since 1980. One of the main arguments in favour of the introduction of summer time at the time was the hope of saving energy. The idea was that because it would be light for an hour longer, the lights would only be switched on an hour later. By setting the clock forward in summer, daylight would be better utilised and therefore less artificial light would be needed. There are now considerable doubts as to the effectiveness of this measure, which is why the abolition of the time change is being considered.

When will the clocks change again in 2025?

In Germany, the time change from summer time to winter time will take place in 2024 on Sunday, 26 October.

When will the clock switch back to summer time?

The return to summer time will then take place on the last Sunday in March, 29 March 2026, i.e. after exactly 154 days or 5 months and 3 days.

Is the clock set forwards or backwards?

During the second time change in 2025, the clock will turn back one hour at 3 am. Deferred. This means that 3 o'clock becomes 2 o'clock. There is one hour more sleep. So although it gets light an hour earlier, it also gets dark an hour earlier. Sporty cyclists should bear this in mind when planning their training. They should take bicycle lights with them on their after-work rides. This also applies to commuters.

When will the clock changeover be abolished?

In recent years, there has been increasing discussion about the possibility of abolishing the clock changeover. Those in favour argue that the changeover is not necessary due to the aforementioned health risks (further down) and the low energy savings are no longer in keeping with the times. Opponents, on the other hand, emphasise that the time change is a long-standing tradition and has certain advantages.

The European Union (EU) has been discussing an end to the time change for a long time. It was supposed to be abolished as early as 2018, with the European Commission presenting a draft law that was approved by the European Parliament. However, the abolition of the time change was postponed until 2021. However, as the EU member states have not followed suit, little has happened since then. There are sometimes many different views on the subject in the member states, which makes it very complicated to reach an agreement.

How does the time change affect the body?

The clock change can affect both our bodies and our everyday lives:

  1. Sleep disordersMany people find it difficult to adapt to the new sleep rhythm. Especially after the changeover to summer time, many complain about problems falling asleep or insomnia.
  2. Concentration difficultiesThe altered biorhythm can lead to temporary concentration difficulties.
  3. Change in the daily routineThe time change can also affect everyday life, as the times for meals, starting work and leisure activities such as cycling can change.

How does the time change affect bike training?

Changing the time of day can affect the training schedule of bikers:

  1. Change in daylightWith the switch to winter time, athletes have less daylight available in the evening. Training outside after work is therefore generally only possible in the dark and with lights on the bike.
  2. Adjustment of the sleep rhythmThe time change can lead to temporary sleep disturbances as the biorhythm has to adapt to the new time. However, it is important to get enough sleep in order to perform optimally during bike training.

What can cyclists do to combat the effects of the time change?

There are a few strategies to minimise the effects of the time change on bike training:

  1. Sleep hygieneMake sure that you create a pleasant environment before going to bed and darken the bedroom to promote restful sleep. Switching off electronic devices in the immediate vicinity can also help.
  2. Relaxation techniquesRelaxation techniques such as yoga or meditation can help to reduce stress and prepare the body for the new sleep rhythm.
  3. Adaptation of the training planAdjust your bike training plan accordingly to allow sufficient time for rest and recovery.

Are there any health risks associated with the time change?

The time change can cause health problems for some people with Jetlag-like symptomsSimilar to jet lag, fatigue, sleep disorders and concentration problems can occur.

How can I prepare for the time change as a bike athlete?

There are a few measures that cyclists can take to make the transition to winter and summer time easier:

  1. Step-by-step customisation: A few days before the time change, you can gradually adapt your training sessions to the new time. Start by slowly adjusting your getting up and going to bed times.
  2. Nutritional adjustmentsMake sure that you consume enough nutrients during the transition to ensure you have enough energy and stamina on the bike.
  3. Training in the groupTrain with other bikers to get motivation and support during the transition to the new era.
