Training Through the Clock Change: Adapting Your Routine as the Days Get Shorter

The clocks go back in the UK on Sunday 25 October 2026, and for anyone who trains outdoors or relies on daylight to get moving, it's one of the most disruptive points in the training calendar. Darker evenings and a sudden hour's shift can derail even a solid routine. Here's how to adapt without losing momentum.

Why the Clock Change Hits Training Harder Than You'd Expect

It's not just about losing daylight; it's about losing it all at once. A gradual seasonal dimming is easy to adjust to; a sudden hour's shift disrupts both your schedule and your body clock simultaneously. If your usual session happens after work, you may go from training in daylight to training in the dark literally overnight, which affects motivation, visibility for outdoor training, and even your natural energy rhythm as melatonin production shifts earlier in the evening.

Practical Adjustments for the Weeks Around the Change

Shift your session earlier where you can. If your routine depends on natural light, moving a session 30–60 minutes earlier in the weeks around the change can preserve outdoor training time before it gets dark.

Prioritise visibility if training outside after dark. Reflective clothing, a head torch for runs or walks, and sticking to well-lit, familiar routes all matter more once evenings close in.

Build in a longer warm-up. Cooler temperatures mean muscles and joints take longer to warm up properly, and research on seasonal training patterns consistently shows that inadequate warm-up in colder conditions is linked to a higher risk of strain injuries.

Expect a short adjustment period, not a lost season. Most people find their energy and motivation dip for 1–2 weeks after the clock change before adapting to the new light pattern. Planning for this rather than being discouraged by it makes it much easier to stay consistent.

Moving Training Indoors Without Losing Progress

If outdoor training becomes impractical, the goal is maintaining the same training stimulus, not replicating the exact session. A few practical swaps:

An outdoor run becomes a treadmill session or a structured indoor circuit at a similar intensity

Outdoor strength circuits move to a gym or home-based resistance session covering the same muscle groups

Group outdoor sessions can often move to an indoor equivalent — the social accountability matters as much as the session itself for consistency

Fuelling Darker, Colder Sessions

A few nutrition habits that make winter training easier to sustain:

Warming up nutrition too — a snack with protein and a little fat digests more slowly, which can help sustain energy through a colder, often longer indoor session

Hydration doesn't stop mattering in the cold — reduced thirst sensation in cooler weather often leads people to under-hydrate without realising it

Simple, no-prep snacks help maintain consistency when darker evenings already make getting out of the door harder
