As the days get shorter and the weather turns colder, it can feel like your training momentum is grinding to a halt. But December is actually one of the most important months in the entire build toward next year’s race season — especially if you’re preparing for events like the BC Bike Race.
Think of December as the bridge month: you’re carrying the fitness you built in the fall into the structured, targeted work that starts in January. The key is staying consistent, staying healthy, and adapting your training to the realities of winter.
In this post, I’ll cover how to navigate daylight limitations, winter weather, indoor training, reduced volume, and holiday stress.
Why December Training Matters More Than You Think
December is often misunderstood as a “throwaway month”—a time when fitness slides and training becomes optional. The truth is this: If you arrive in January motivated and healthy, you’re already ahead of 80% of athletes. December sets that foundation.
During this month, your goals should be:
• Maintaining aerobic durability
• Preserving consistency
• Avoiding injury and illness
• Keeping motivation high
• Managing lifestyle stress
It’s not about maximum volume or peak intervals — it’s about maintaining readiness.
How to Train When Daylight Is Limited
Short days are one of the biggest barriers to winter consistency. But with a strategic approach, you can stay on track without adding stress.
Shift Workouts to Bright Hours
• Ride at lunch when possible
• Use flexible work breaks
• Prioritize weekend daylight windows
Lean Into Shorter Sessions
A 45–60 minute Z2 ride outdoors still counts — and those small commitments add up fast.
Think frequency over duration.
Use Proper Winter Gear
Invest in:
• Good lights
• Waterproof gloves and booties
• Thermal layers that don’t trap sweat
The right gear turns “unrideable days” into solid training opportunities.
Training in Cold, Wet, and Snowy Weather
Riding outdoors in winter requires good decision-making and smart adjustments.
Know When to Ride Outside vs. Inside
Ride outside when:
• Roads or trails are dry
• Temperatures are cold but safe
• Visibility is good
Ride indoors when:
• It’s icy or dangerous
• Heavy snow is falling
• Windchill is extreme
Modify Your Terrain Choices
• Gravel or MTB is often safer than road in winter
• Snow-packed trails work well for fat-biking
• Lower tire pressures increase traction on cold, wet surfaces
Winter Alternatives Count Too
• Snowshoeing
• Power hiking
• Nordic skiing
• Gym-based aerobic work
Your cardiovascular system only knows intensity and duration, not activity labels.
How to Adapt Outdoor Workouts for the Indoor Trainer
Indoor training is a winter superpower — if you use it correctly.
Match the Stimulus, Not the Terrain
The body doesn’t care if an interval was indoors or outdoors. It recognizes:
• Intensity
• Duration
• Total stress
Guidelines for Converting Workouts Indoors
• Shorten Z2 rides by 15–20%
• Keep tempo and big-gear strength endurance workouts (SE)
• Use threshold intervals sparingly but effectively
• VO2 work should be shorter and highly controlled
Indoor Training Tips
• Use a strong fan to keep core temperature stable
• Fuel exactly as you would outside
• Hydrate more than you think
• Avoid doing everything in ERG mode — you want to learn how to pace, not just survive the workout
Key Principles for December Training (Especially When Volume Drops)
December isn’t usually a high-volume month — and that’s okay. What matters is how you manage the training you can do.
1. Prioritize Frequency Over Long Rides
Consistent touches on the bike maintain aerobic fitness exceptionally well.
2. Keep One High-Quality Workout Each Week
A small amount of intensity keeps your threshold from drifting down.
3. Strength Training Takes Center Stage
Build muscular durability now with:
• Squats
• Hinges
• Single-leg work
• Rotational strength
• Mobility
This base will pay dividends in spring and during multi-day events like BCBR.
4. Don’t Neglect Nutrition
• Aim for 30–40g protein per meal
• Fuel all rides, even short indoor sessions
• Keep hydration consistent
5. Sleep Is Your Hidden December Advantage
Longer nights = better recovery potential — if you let it.
Balancing Holiday Stress With Training
Training stress isn’t the only stress you’re managing in December. Life loads can spike quickly with:
• Family gatherings
• Social events
• Holiday travel
• Work deadlines
• Shopping and logistics
Your body doesn’t separate training stress from lifestyle stress — it all fills the same bucket.
Smart Holiday Training Adjustments
• Maintain frequency
• Shorten duration when needed
• Be flexible — shuffle sessions without guilt
• Use indoor workouts for time efficiency
The “Bookend Eating” Strategy
Before events:
• Eat a high-protein, high-fiber meal
• Hydrate well
At events:
• Enjoy yourself
After events:
• Rehydrate
• Return to normal eating ASAP
Small guardrails keep things on track.
Final Thoughts: December Is About Momentum, Not Perfection
December training isn’t about getting fitter — it’s about not losing the fitness you’ve built, and more importantly, staying healthy and motivated for the training phases ahead.
Focus on:
• Consistency
• Adaptability
•Managing stress
• Smart indoor sessions
• Strength work
• Good sleep and nutrition
Get those right and you’ll roll into January ready to build the engine you’ll need for a successful season — including the BC Bike Race.
