As temperatures drop and the race calendar slows, autumn is the perfect time to focus on recovery, rebuilding, and staying healthy. Between muddy training sessions and unpredictable weather, your body needs the right fuel to keep energy levels high and immunity strong.

Here’s how to eat smart this season so you’re ready to smash your next OCR challenge — no matter the weather.

1. Stay Strong Against Seasonal Bugs

Colder, wetter weather means more time indoors — and more chances to pick up colds and viruses. Support your immune system with a mix of key nutrients:

  • Vitamin D: With less daylight, most of us become deficient. Supplement 10µg daily through winter to maintain energy and immunity.

  • Vitamin C and Zinc: Load up on peppers, citrus, kiwis, and nuts to support immune cell function and repair.

  • Iron: If you’re feeling sluggish or pale, it might be low iron. Add lean meat, lentils, or spinach to your meals.

These basics can make the difference between powering through winter or losing weeks to fatigue and illness.

2. Keep Energy Levels Steady

When it’s dark and cold, comfort food cravings hit hard. But sugar highs and lows make training feel tougher than it should.
Swap quick-fix snacks for slow-release carbs like:

  • Oats, sweet potatoes, and brown rice

  • Lentils and beans

  • Seasonal root veg like carrots and parsnips

Pair these with lean protein and healthy fats to keep your blood sugar — and energy — consistent all day long.

3. Eat Enough to Recover

It’s easy to underfuel when your training volume dips, but your body still needs calories to recover and adapt.
Aim for balanced meals with a solid source of protein (chicken, fish, tofu, eggs) at every sitting. For most OCR athletes, that’s around 1.6–2g of protein per kg of bodyweight per day.

If you’re training outdoors in cold conditions, you’re likely burning more than you think — so don’t be afraid to top up with hearty, nutrient-rich meals. Think stews, curries, soups, and grain bowls packed with colourful veg.

4. Hydrate Even When It’s Cold

Colder weather can trick you into drinking less, but dehydration still hits performance and recovery hard.
Sip water regularly throughout the day, and include hydrating foods like fruit, soups, and herbal teas. A good rule of thumb: your urine should be pale yellow, not dark.

5. Eat the Season

Autumn’s produce is loaded with slow-release energy and antioxidants to fight fatigue. Fill your plate with:

  • Pumpkins, squashes, and sweet potatoes

  • Kale, broccoli, and Brussels sprouts

  • Apples, pears, and beetroot

These are nutrient powerhouses — and they taste great roasted, in soups, or blended into recovery smoothies.

6. Keep It Simple and Consistent

You don’t need a complicated meal plan to stay healthy this autumn. A few small habits go a long way:

  • Add one extra portion of colourful veg to each meal

  • Prep healthy snacks for post-training hunger

  • Take your daily vitamin D supplement

  • Stay hydrated and fuel properly before and after every workout

The Bottom Line

Autumn is your chance to build the foundation for next season’s performance. Eat well, stay fuelled, and give your immune system what it needs to thrive. The better you recover now, the stronger you’ll race when OCR season kicks off again.
