Hello Runner,
Welcome back to your weekly moment of endurance nutrition!
Happy Weekend!
How was your week?
My week was very busy with lots of work and tasks to finish. I also trained almost every day (except yesterday, when my PMS headache got the better of me).
I don't usually skip training, I only skip it when I really can't go. And yesterday was one of those days. We need to listen to our bodies, too.
Despite everything, I've been sleeping very well lately, even when I train on Wednesday nights. But I know that this isn't the reality for many runners.
With that in mind, today I want to talk about how late workouts shouldn't disrupt your sleep. And what to do if they do.
If you train in the evening, you’ve probably thought this at least once:
→ “Is my late running hurting my sleep?”
The reassuring affirmation for most runners is no: evening training doesn’t automatically disrupt sleep. In fact, recent research shows that evening exercise can actually improve sleep quality, as long as the session isn’t overly intense and you support recovery well.
Where things can get tricky are intensity, timing, and recovery habits. Let’s check each one, so you can keep training consistently and sleeping deeply.
The sessions most likely to disrupt sleep are high-intensity workouts done late at night, such as:
Hard interval sessions
VO₂ max workouts
Long tempo runs finished close to bedtime
These sessions strongly activate your nervous system, elevate stress hormones, and keep your body in “go mode” when it should be winding down. If you’ve noticed:
Trouble falling asleep
Restless or fragmented sleep
Higher nighttime heart rate
It’s often a sign that something needs adjusting, not that evening training is a bad idea.
Recent studies show that light to moderate evening exercise supports sleep, not harms it. Easy runs, relaxed aerobic sessions, or strength work at a moderate load can:
Improve sleep efficiency
Increase deep sleep
Help regulate circadian rhythm
So the goal isn’t to avoid evening training, it’s to match the right intensity to the right time of day.
FUELING & STRATEGIES
Fueling at night: recovery and better sleep
One of the most overlooked sleep tools for runners is nutrition.
A pre-bed meal or snack with carbohydrates and protein can:
Support muscle repair and glycogen replenishment
Reduce nighttime awakenings
Promote relaxation and serotonin production
Examples:
Protein shake or Protein-packed Smoothie
Oatmeal with banana and walnuts
Toast with cottage cheese + kiwi
Here, the main goal is to fuel recovery so your body can fully relax.
Pre-bed strategies that actually help
To support sleep after evening workouts, focus on building good sleep hygiene:
Warm, caffeine-free teas (lavender or chamomile)
Consistent sleep routine (same bedtime, low light)
Screen dimming or blue-light filters 60–90 minutes before bed
Breathing exercises or gentle stretching
Cool, dark, quiet bedroom environment
These are performance tools.
Remember: sleep is where adaptation happens.
Use your data—but listen to your body
Your sports watch can be a powerful feedback tool. Try comparing:
Sleep duration and quality
Resting heart rate
HRV trends
on days with evening training vs. non-training days.
If you want more and better, pair that data with a simple training or sleep diary. Journal:
Workout type and intensity
What and when you ate
How you felt falling asleep and the next morning
Patterns emerge quickly, and they’re far more useful than generic rules.
Evening training can absolutely fit into a high-performance lifestyle. If sleep is suffering, it doesn’t mean you’re doing something wrong; it means something needs fine-tuning:
Adjust intensity
Support recovery with food
Improve your wind-down routine
Consistency, not perfection, is what drives results!
Product of the Week
This week's Product of the Week is the MyHalos sleeping mask.
This mask was a great find for me.
During spring and summer, a lot of light comes into my room and interrupts my sleep. My brain turns on, and I can't turn it off.
This mask really helps keep the light out, even when the sun is already rising.
For those who don't have a completely dark room to sleep in, I highly recommend this mask.
Track of the Week 🎧️
This week's Track of the Week is a song by a band I love (and which I've already mentioned here in the newsletter), and I think it's great to listen to during lighter evening workouts.
I’ve chosen Sun by Two Door Cinema Club

Here’s to health and good runs⚡️
