Autumn can be one of the best times of year to run in the UK. Cooler temperatures provide welcome relief after summer, parks and countryside routes change colour, and familiar runs can feel completely different as the seasons shift.
However, September and October also bring increasingly changeable weather, shorter daylight hours and wetter surfaces. The Met Office's guide to UK autumn weather notes that the season is typically characterised by falling temperatures, shorter days and increasingly unsettled conditions as winter approaches.
Rather than abandoning your usual routine, a few practical adjustments to clothing, pacing, routes and recovery can help you continue running comfortably throughout the season.
Dress for the Conditions, Not the Calendar
One of the challenges of autumn running is deciding what to wear. A chilly start can quickly become surprisingly warm once you have been moving for ten minutes, while sunshine can give way to wind or rain midway through a session.
Lightweight layers generally provide more flexibility than one thick piece of clothing. Start with a breathable, moisture-wicking running top rather than cotton, which tends to hold moisture against the skin. On cooler days, add a light long-sleeved layer or running jacket that can protect you from wind and showers without becoming excessively warm.
Accessories can also be useful as temperatures fall. Lightweight gloves or a headband are easy to remove if you warm up, making them more adaptable than immediately switching to heavy winter clothing.
Checking the forecast before leaving becomes increasingly important during autumn, particularly for longer routes where conditions may change while you are out.
Give Yourself Longer to Warm Up
Heading straight from a warm house into cool air and immediately trying to hit your normal pace is rarely the most comfortable way to begin a run.
The NHS recommends warming up properly before exercise and provides a routine lasting at least six minutes. Its running guidance also recommends beginning runs with around five minutes of walking to gradually raise the heart rate and warm the muscles.
Before heading outside, try a few minutes of dynamic movement such as marching, gentle squats, leg swings or lunges. Once you begin running, use the first few minutes as an extension of the warm-up rather than immediately chasing your usual pace.
Autumn does not automatically mean you need to run more slowly, but allowing your body time to settle into the session can make cooler starts considerably more comfortable.
Prepare for Darker Runs
Daylight disappears quickly at this time of year. In 2026, the clocks go back on 25 October, making evening daylight noticeably more limited from that point onwards.
If you regularly run before or after work, reconsider routes that were perfectly suitable during summer but become poorly lit in autumn.
Choose pavements, parks and routes you know well, and take particular care around roads, crossings and shared paths. The Highway Code advises pedestrians to wear bright or fluorescent items in poor daylight and reflective materials after dark, helping other road users see them more easily.
Reflective running clothing, lights and a headtorch are worthwhile additions if you expect to run after sunset. A headtorch is particularly useful on poorly illuminated paths because visibility is not only about being seen — it also helps you identify uneven surfaces before stepping on them.

Do Not Forget About Hydration
Cooler weather can make hydration easier to overlook because you may not feel as hot or thirsty as you would during July.
Your fluid requirements do not disappear with summer, however, and exercise increases the amount you need. For normal day-to-day hydration, NHS guidance recommends most people aim for around six to eight cups or glasses of fluid each day, with additional fluid likely to be needed when physically active.
Drink regularly throughout the day rather than trying to compensate immediately before running. For most shorter recreational runs, there is no need to make hydration complicated.

Watch Out for Wet Leaves and Slippery Surfaces
Autumn scenery might look impressive, but fallen leaves can create surprisingly hazardous running surfaces.
Once wet, leaves can reduce traction and conceal kerbs, potholes, tree roots and uneven paving. Slow down when approaching heavily covered sections rather than assuming the ground beneath them is level.
Check the tread on your running shoes too. The NHS advises using appropriate running footwear as part of reducing the risk of common running injuries.
Trail runners may benefit from footwear with additional grip when moving regularly onto muddy paths, although there is no need to replace suitable shoes purely because the season has changed.
Adapt the Routine When Conditions Are Poor
Consistency does not mean completing exactly the same session regardless of weather or conditions.
If strong winds, heavy rain or particularly slippery paths make a planned interval session unsuitable, swap it for an easier run, treadmill session or another form of cardiovascular exercise. Our guide to low-impact cardio workouts offers several alternatives for days when running outdoors is less appealing.
Rest also remains part of effective training. If your performance is declining consistently or fatigue is building despite continuing to train, our article on recognising the signs of overtraining explains when reducing your training load may be sensible.
Keep Motivation Simple
The hardest part of autumn running is sometimes getting through the front door.
Preparing your clothes the night before, choosing specific running days in advance and arranging to run with somebody else can remove some of the decision-making involved when the weather looks uninviting.
Avoid setting yourself an unrealistic standard where every summer session must continue unchanged throughout autumn. Our guide to setting realistic health goals explores why habits tend to be easier to maintain when they are built around your actual circumstances rather than an idealised routine.
Autumn running is ultimately about adapting rather than stopping. Dress appropriately, give yourself time to warm up, stay visible, respect changing surfaces and adjust your training when conditions demand it. Done well, those cooler and quieter runs could become some of the most enjoyable sessions of your year.
