Why Cycle Through Winter

The cyclists who emerge strongest in spring are those who trained through winter. While others hibernate, you can build a massive aerobic base, maintain bike handling skills, and stay mentally sharp for the season ahead.

Winter cycling isn't for everyone, but for those who embrace it, there's something magical about empty roads, crisp air, and the satisfaction of doing what others won't. Plus, you maintain fitness instead of spending spring rebuilding it.

The Off-Season Advantage: Professional cyclists don't take winter off - they use it for base building. The aerobic foundation built in winter supports high-intensity work in spring. Skip winter training and you'll spend spring catching up.

Cold Weather Physiology

Your body works differently in cold conditions. Understanding these changes helps you train and dress appropriately.

Key Physiological Effects

  • Blood flow shifts: Body prioritizes core temperature, reducing blood to extremities
  • Heart rate changes: May be lower in cold due to increased blood viscosity
  • Caloric burn: Slightly higher to maintain body temperature
  • Breathing: Cold air can irritate airways; breathe through nose or use balaclava
  • Power output: May be lower initially but normalizes as you warm up

Warm Up Matters More: In cold weather, extend your warm-up. Blood flow to muscles is restricted initially. A thorough 15-20 minute warm-up prevents injury and improves performance.

Essential Cold Weather Gear

Proper gear makes winter cycling enjoyable rather than miserable. Invest in quality cold weather kit.

Layering System

Layer Purpose Materials
Base LayerWicks sweat away from skinMerino wool, synthetic wicking fabrics
Mid LayerInsulationFleece, thermal jersey
Outer LayerWind/water protectionSoftshell jacket, wind vest

Temperature-Based Gear Guide

50-60°F (10-15°C): Cool

Arm warmers, knee warmers, light gilet, full-finger gloves

40-50°F (4-10°C): Cold

Thermal jersey, leg warmers or tights, wind jacket, warm gloves, toe covers

30-40°F (-1 to 4°C): Very Cold

Base layer + thermal jersey + jacket, winter tights, winter gloves, shoe covers, headband/ear covers

Below 30°F (below -1°C): Extreme

Full winter kit: thermal base, heavy jacket, bib tights, lobster gloves, winter shoes or heavy covers, balaclava, consider indoor trainer

Extremities Are Key

Your hands, feet, and head lose heat fastest. Invest heavily in:

  • Gloves: Lobster gloves (2-finger) provide warmth + control
  • Shoe covers: Neoprene or Gore-Tex overshoes
  • Head covering: Thin cap under helmet, or balaclava in extreme cold

Bike Setup & Maintenance

Winter conditions are hard on bikes. Prepare your setup and maintain it diligently.

Tire Selection

  • Run slightly wider tires for stability (28-32mm if possible)
  • Reduce pressure 5-10 PSI for better grip
  • Consider puncture-resistant tires (winter debris)
  • Studded tires for ice (dedicated winter bike)

Fenders/Mudguards

Essential for wet roads. Fenders keep water, mud, and road grime off you and your bike. Full fenders front and rear make winter riding far more pleasant.

Maintenance Schedule

  • After every wet ride: Wipe down frame, clean and lube chain
  • Weekly: Check brake pads (wear faster in winter), inspect tires
  • Monthly: Deep clean drivetrain, check cables
  • Use wet lube: Dry lube washes off in winter conditions

Safety in Winter Conditions

Visibility

Winter means shorter days and low-angle sun. Be seen:

  • Front and rear lights - always (day or night)
  • Hi-vis clothing, reflective elements
  • Avoid riding during worst visibility (dusk in rain)

Slippery Surface Awareness

  • Ice: Most dangerous in early morning and shaded areas
  • Wet leaves: Extremely slippery - avoid like ice
  • Painted lines: Slippery when wet
  • Metal surfaces: Grates, manhole covers - avoid when wet

The Black Ice Rule: If the road looks wet but it hasn't rained and the temperature is near freezing, it might be black ice. Ride extremely cautiously or go home. No training ride is worth a serious crash.

Indoor vs Outdoor Balance

The best winter training combines indoor and outdoor riding. Each has advantages:

Indoor Training Benefits

  • Consistent, controllable conditions
  • Safe regardless of weather
  • More time-efficient (no kit changes)
  • Perfect for structured workouts
  • No bike wear from winter conditions

Outdoor Riding Benefits

  • Maintains bike handling skills
  • Mental health/variety benefits
  • Vitamin D from sunlight
  • Social riding opportunities
  • Builds mental toughness

A typical winter split: 60% indoor, 40% outdoor (weather permitting). Do structured work indoors; save outdoor rides for when conditions are reasonable.

Learn more about indoor training in our Zwift and indoor cycling guide.

Winter Training Structure

Winter is typically the "base" or "off-season" phase. Training focus shifts from racing to building foundation fitness.

Sample Winter Training Week

  • Monday: Rest or easy spin/yoga
  • Tuesday: Indoor - structured workout (sweet spot or tempo)
  • Wednesday: Indoor - Zone 2 endurance
  • Thursday: Indoor - intervals or rest
  • Friday: Rest
  • Saturday: Outdoor - longer ride if weather permits (or indoor long session)
  • Sunday: Zone 2 ride or group ride

Total: 8-12 hours depending on fitness level

Base Building Focus

Winter base training emphasizes aerobic development at lower intensities, preparing you for higher-intensity work in spring.

Zone 2 Emphasis

The majority of winter training should be in Zone 2 (endurance pace). This builds mitochondrial density, capillary networks, and aerobic enzymes. See our Zone 2 training guide for details.

Strength Work

Winter is ideal for gym strength training. Build leg strength, core stability, and address muscular imbalances. Reduce strength work as racing season approaches.

Maintain Some Intensity

Pure base training doesn't mean no intensity. Include one session per week of tempo, sweet spot, or VO2max work to maintain top-end fitness. Just don't overdo it - save peak intensity for racing season.

Mental Strategies

Winter cycling tests mental fortitude. Here's how to stay motivated:

  • Set winter-specific goals: FTP gain, volume target, weight loss
  • Join group rides: Accountability and social connection
  • Zwift races/events: Add competition and variety to indoor training
  • Reward outdoor rides: Cafe stops, new routes, fun with friends
  • Track progress: Seeing improvement maintains motivation
  • Accept bad days: Not every ride needs to be epic

Nutrition in Cold Weather

Cold weather affects nutritional needs:

  • Higher calorie burn: Body works to maintain temperature - you may need more fuel
  • Less thirst: Cold suppresses thirst but you still lose fluids - drink deliberately
  • Warm options: Warm drinks in bottles (coffee, tea), keep bottles inside jacket to prevent freezing
  • Eat before getting cold: Once shivering, digestion becomes difficult

Frequently Asked Questions

Is it safe to cycle in winter?

Yes, with proper precautions: appropriate tires, bright lighting, visible clothing, slower speeds on slippery surfaces, and checking conditions before riding.

What temperature is too cold for cycling?

It depends on gear and tolerance. Most are comfortable to 20-30°F with proper layering. Below 20°F requires extreme caution. Below 0°F, most opt for indoor training.

How do I keep my feet warm?

Winter shoes or shoe covers, thermal socks (not too thick), toe warmers, waterproof overshoes, and keeping your core warm (cold core = cold extremities).

Should I ride outdoors or use a trainer?

Both. A mix is ideal - 50-70% indoors, 30-50% outdoors when conditions allow. Indoor for structured work, outdoor for skills and variety.
