Finding the Perfect Openers: What Science Says About Pre-Race Cycling Workouts

If you've ever felt sluggish at the start of a race or struggled to hit your rhythm early on, you’re not alone. Many cyclists use openers—short, high-intensity efforts performed the day before or the morning of an event—to activate their muscles and prepare for peak performance. But with so many different strategies, how do you know which pre-race warm-up is best for you?

In this article, we break down four key studies on warm-ups and openers, highlighting their findings and practical applications. Whether you’re racing a time trial, criterium, or road race, you’ll learn how to fine-tune your warm-up routine to maximize race-day performance.

TL;DR – Pre-Race Warm-Up Cheat Sheet

Day-Before Race Openers

3-5 high-intensity sprints to activate muscles (Garvick, Chorley & Lamb)
10-15 min progressive warm-up ride (Burnley)
3-4 min VO2 Max effort (Bailey)
Avoid excessive fatigue—keep efforts sharp but controlled

Race-Day Warm-Up

Short, high-intensity bursts (2-3 reps) to fire up neuromuscular system (Burnley)
Keep intensity but avoid over-exertion—balance effort with recovery

Key Cycling Performance Terms

 

Post-Activation Potentiation (PAP)

Definition: A short-term boost in muscle performance following a high-intensity effort. PAP increases neuromuscular efficiency, leading to improved sprint power and initial acceleration.

Example: A cyclist performing high-resistance sprints before a race to enhance explosive power at the start.

Oxygen Uptake (VO₂) Kinetics

Definition: The rate at which muscles absorb and use oxygen during exercise. Faster VO₂ kinetics mean a cyclist can reach optimal aerobic performance faster, reducing early-race fatigue.

Example: A structured warm-up can help cyclists hit their ideal power zones sooner, improving endurance.

Respiratory Exchange Ratio (RER)

Definition: A measure of how the body fuels performance—higher RER means more carbohydrate use, lower RER indicates greater fat metabolism.

Example: Cyclists who optimize their warm-up may rely more on fat stores early on, preserving glycogen for later race efforts.

Why We Chose These Four Studies

These studies explore different aspects of pre-race preparation:

-Oxygen uptake and performance improvements (Bailey et al.)

-The effects of warm-up on cycling time trials (Burnley et al.)

-High-intensity, heavy-resistance warm-up methods (Chorley & Lamb)

-The impact of opener workouts 24 hours pre-race (Garvick)

Future research should focus on direct comparisons of different opener strategies, larger sample sizes, and real-world race conditions to refine recommendations for competitive cyclists.

Study Comparison Table

Workout Type Duration Warm-Up Main Set Cool-Down
Day-Before: Short High-Intensity Priming 45–60 min 15–20 min easy spin 3 × 30-sec sprints (~90–95% max, 3 min recovery)
2–3 min at FTP or just above
5–10 min easy spin
Day-Before: Aerobic + Neuromuscular Activation 60 min 20 min progressive build (Zone 1–2) 2 × 3 min at VO₂ max (3 min recovery)
3 × 10-sec max sprints (2 min recovery)
10–15 min easy spin
Race-Day: Time Trial Warm-Up 30–40 min 10 min easy spin 5 min tempo (Zone 3)
3 min threshold (Zone 4)
3 × 30-sec VO₂ max efforts (2 min recovery)
5 min easy spin
Race-Day: Criterium Warm-Up 20–30 min 10 min easy spin 3 × 1 min at threshold (2 min recovery)
2 × 10-sec max sprints (2 min recovery)
5 min easy spin
Race-Day: Road Race Warm-Up 15–20 min 10 min easy spin 1–2 × 30-sec hard effort (~90% max) 5 min easy spin

Key Takeaways for Cyclists

PAP warm-ups may enhance short, high-intensity efforts (Chorley & Lamb).
Longer endurance races may not benefit from high-intensity warm-ups (Garvick).
Overly intense warm-ups may cause fatigue (Bailey).
Experiment with different warm-up routines—what works for one cyclist may not work for another.

Final Thoughts: Finding Your Best Warm-Up Strategy

🔥 Use day-before openers to activate your system without overloading your muscles.
🚴‍♂️ Incorporate short, high-intensity efforts in race-day warm-ups for peak power.
📊 Track how different warm-ups impact your performance to personalize your strategy.
Balance warm-up intensity with recovery—don’t fatigue your legs before the race even starts!
