When the Clocks Fall Back: Adjusting Your Training, Sleep and Meal Timing for Dark Evenings
The extra hour on Sunday is nice. The 5 p.m. darkness that follows isn't. Here's how to keep your training, sleep and protein on track once daylight saving time ends.
The clocks fall back this Sunday, November 1. You get an extra hour of sleep, and then it's dark by about 5 p.m. If you train before or after work, that shift can throw your routine off for weeks: the after-work run is suddenly in the dark, the gym feels harder to get to, and dinner, protein and bedtime all move around. Here's how to adjust your training, warm-ups, visibility, sleep and meal timing so the dark months don't cost you progress.
What actually changes when the clocks fall back
At 2:00 a.m. local time on Sunday, November 1, most of Canada sets its clocks back one hour. Sunrise and sunset both arrive an hour earlier on the clock. Your body clock doesn't move overnight, though. For the first few days, 6 a.m. will feel like 7 a.m., and you'll likely get hungry and sleepy "early."
Not everyone changes. Most of Saskatchewan and all of Yukon stay on the same time all year, as do some communities in other provinces. If you're not sure about your area, check the National Research Council's official time page.
Morning or evening? Choosing your training slot for the dark months
For a few weeks after the change, mornings get a bit of light back, while evening sessions move fully into darkness. Both can work. Here's how they compare:
- Morning sessions: you get them done before work gets in the way, and you may catch some early daylight. The downside is cold muscles and an early alarm.
- Evening sessions: many people feel more warmed up later in the day, and you're not rushing to beat the morning clock. The downside is darkness, cold and the pull of the couch once you're home.
The best slot is the one you can repeat. Weekly consistency does far more for you than the time on the clock. Canada's 24-Hour Movement Guidelines recommend adults get at least 150 minutes of moderate to vigorous activity a week plus muscle-strengthening work at least twice a week. Pick the time that gets you there reliably.
Ease into the shift: the first week
You don't have to take the time change all at once. For the first week:
- Move things gradually. Shift bedtime, meals and sessions by 15 to 20 minutes a day until you're on the new schedule.
- Keep your wake time steady. A consistent alarm, weekends included, keeps everything else in line.
- Get outside early. A walk or a coffee in the morning light helps you feel awake when the day starts.
- Go easy on intensity. If you're sleeping badly for a few nights, swap the hardest workout for a moderate one and push again next week.
Warm up longer when it's cold and dark
Cold muscles and stiff joints need more time to get ready, especially if you've spent the day at a desk. Build a longer warm-up into the dark months:
Easy cardio such as brisk walking, light jogging, rowing or cycling until you're breathing a bit harder and starting to feel warm.
Leg swings, walking lunges, hip openers and arm circles, then a few ramp-up sets or strides before your first hard effort.
Start in more layers than you think you need and take them off as you warm up. A Signature Toque keeps your head warm on the walk to the gym or the first kilometre outside.
Be seen: outdoor running and cycling after dark
If your runs or rides now happen in the dark, visibility is the priority:
- Wear bright and reflective layers. Reflective bits on moving parts (ankles, wrists) catch drivers' eyes best.
- Use lights front and back. A headlamp or chest light lets you see the ground, and a rear light lets traffic see you.
- Choose lit routes. Stick to well-lit streets, paths and tracks, and save trails for weekend daylight.
- Run against traffic where there's no sidewalk, so you can see what's coming.
- Tell someone your route and when you expect to be back.
Retiming meals and post-workout protein
When your schedule shifts, your meals shift with it. The good news is that the total matters most. The International Society of Sports Nutrition (ISSN) suggests roughly 1.4 to 2.0 g of protein per kilogram of body weight a day for most people who exercise, spread as doses of about 20 to 40 g every three to four hours. Here's how that fits around dark-month training:
Something small and easy, like a banana, toast or a light shake, if you train hard. If you're going easy, water may be all you need.
A mid-afternoon snack with carbs and some protein, about two to three hours before training, so you're not running on lunch.
A meal or shake with 20 to 40 g of protein. A quick Whey Protein Isolate shake is handy when dinner is still an hour away.
If protein is hard to fit into a late evening, the ISSN's position on nutrient timing notes that 30 to 40 g of casein before sleep can support overnight muscle protein synthesis. Micellar Casein fits that slot.
Protecting sleep when you train late
Evening training is fine for most people, but a few habits help you wind down afterwards:
- Finish hard sessions a couple of hours before bed when you can, and keep the latest workouts moderate.
- Watch late-day caffeine. Caffeine can stay in your system for hours, so think twice about coffee or a stimulant pre-workout in the late afternoon or evening. Choose a caffeine-free option, or none at all, for late sessions.
- Build a cool-down routine: easy movement, stretching, a warm shower.
- Dim the lights and screens in the last hour before bed.
Don't forget the sunshine nutrient
Canadian winters mean short days and not much sun on your skin. Your body makes vitamin D when skin is exposed to sunlight, so in the dark months food and supplements matter more. Health Canada's dietary reference intakes set out how much vitamin D adults need each day. Fortified milk, fatty fish and eggs all contribute, and a Vitamin D3 supplement is an option if you're not getting enough from food. Ask your healthcare provider what's right for you.
Keep three things steady: your wake time, your daily protein total and the number of sessions you do each week. Then fit the clock around them.
Training after the time change: FAQ
Should I switch to morning workouts after the time change?
Only if mornings are easier for you to stick to. Morning sessions avoid the evening darkness, but the best time to train is the one you'll keep doing every week.
Is it bad to work out at night?
No. Evening training works well for many people. If you find it hard to fall asleep afterwards, try finishing hard sessions a couple of hours before bed and skipping late-day caffeine.
When should I have protein if I train after work?
Have a snack with some protein mid-afternoon, then 20 to 40 g of protein after training, whether that's dinner or a shake. Hitting your daily total matters more than exact timing.
Does caffeine in an evening pre-workout affect sleep?
It can. Caffeine stays in your system for hours, so for late sessions a caffeine-free pre-workout, or none at all, is the safer choice.
Make your evenings work for you
Dark evenings don't have to cost you progress. Warm up longer, stay visible outside, keep your wake time steady and plan your protein around your new schedule. If your training now finishes late, a casein shake before bed is an easy way to reach your daily protein total.
