What to Wear for Outdoor Training (All Seasons, London Edition)

Training outdoors in London? The right kit makes all the difference.

If you’re joining an outdoor bootcamp, HYROX session, or small group fitness class in one of London’s parks, knowing what to wear can be the difference between enjoying the session or just getting through it. With the right layers and mindset, outdoor workouts become consistent, energising, and something you actually look forward to — no matter the forecast.

At Be Fearsome Outdoors, we train year-round in Hyde Park and beyond. Rain, wind, sun, or snow — our sessions go ahead. And while we bring the energy and structure, you bring the gear.

You don’t need the latest kit or fancy brands. But you do need to be prepared. London weather moves fast, and your comfort can impact your performance, mood, and recovery. This guide covers exactly what to wear for outdoor training in every season so you can stay focused on your fitness, not the forecast.

🌱 Spring: Layers & Light Showers

Weather: Mild, breezy, occasional rain

Focus: Breathability + versatility

What to wear:

• Lightweight moisture-wicking top (long- or short-sleeve)

• Thin waterproof or windbreaker jacket

• Full-length leggings or fitted joggers

• Lightweight hat or headband (optional)

• Trainers with decent grip (watch for wet grass)

  
  

Top tip: Always bring a layer you can take off mid-session. It warms up fast once you get moving.

☀️ Summer: Sun Protection & Sweat Control

Weather: Warm to hot, bright sunshine, occasional humidity

Focus: Sun safety + staying cool

What to wear:

• Breathable tank or tee (moisture-wicking fabric is ideal)

• Shorts or capris

• Light cap or visor

• Sunglasses (if you like)

• SPF 30+ on exposed skin

• Lightweight trainers

  
  

Top tip: Bring water. Hydration matters more than ever in the summer months.

🍂 Autumn: Transitional Layers & Wind Protection

Weather: Cooling down, windier, unpredictable rain

Focus: Adjustability + comfort

What to wear:

• Long-sleeve base layer or mid-weight training top

• Lightweight rain-resistant jacket

• Leggings or joggers

• Beanie or headband if mornings are chilly

• Grippy trainers (especially if leaf fall makes surfaces slippery)

  
  

Top tip: Gloves can help in colder early sessions but avoid anything bulky that affects grip.

❄️ Winter: Warmth Without Bulk

Weather: Cold, damp, windchill

Focus: Insulation + mobility

What to wear:

• Thermal base layer (top and bottom)

• Fleece or insulating mid-layer

• Waterproof shell or windbreaker

• Thermal leggings or tights under joggers

• Beanie, gloves, and maybe a neck gaiter

• Waterproof trainers or trail shoes (if very wet or icy)

  
  

Top tip: Dress for how you’ll feel 10 minutes into the session — not how you feel leaving the house.

Year-Round Essentials

No matter the season, there are a few kit staples that always help:

• Moisture-wicking layers (avoid cotton)

• Weather-appropriate outerwear

• Comfortable, weatherproof trainers

• Water bottle

• Change of top/layers for after training

• A positive mindset (you’ll warm up fast!)

  
  

FAQs: Outdoor Training Gear

Do I need to buy special kit?

No. Start with what you have. Focus on comfort, movement, and weather protection. Build your kit over time.

What about mud and rain?

It happens! Embrace it. Bring a towel or change of clothes if you’re heading somewhere after.

Is there storage on-site?

At Be Fearsome Outdoors, we operate near our mobile gym vans in Hyde Park — so light bags can usually be stowed nearby, but come ready to train hands-free.
