Training zones

This plan uses power zones (% of FTP) and heart rate zones (% of max HR) to guide effort. A power meter and heart rate monitor are required.

Power zones

Zone % FTP RPE Feel
Z1
Recovery		 0-55% FTP 1-2 out of 10 Extremely easy. No sensation of effort. Used only for recovery rides.
Z2
Endurance		 56-75% FTP 3-4 out of 10 Comfortable, sustainable effort. You are working but could maintain this for hours.
Z3
Tempo		 76-90% FTP 5-6 out of 10 Moderately hard. Sustainable for 30-60 minutes but requires concentration.
Z4
Threshold		 91-105% FTP 7-8 out of 10 Hard. You can sustain this for 20-40 minutes with focus. Speaking is difficult.
Z5
VO2max		 106-120% FTP 8-9 out of 10 Very hard. Maximum sustainable effort for 3-8 minutes. Legs and lungs burn.
Z6
Anaerobic Capacity		 121-150% FTP 9-10 out of 10 Maximum effort for 30 seconds to 2 minutes. Not sustainable.
Z7
Neuromuscular Power		 150%+ FTP 10 out of 10 All-out sprint for under 30 seconds. Pure explosive effort.

Heart rate zones

Zone % Max HR Feel
Z1
Recovery		 0-59% max HR Extremely easy. No sensation of effort. Used only for recovery rides.
Z2
Endurance		 60-70% max HR Comfortable, sustainable effort. You are working but could maintain this for hours.
Z3
Tempo		 71-80% max HR Moderately hard. Sustainable for 30-60 minutes but requires concentration.
Z4
Threshold		 81-90% max HR Hard. You can sustain this for 20-40 minutes with focus. Speaking is difficult.
Z5
VO2max		 91-100% max HR Very hard. Maximum sustainable effort for 3-8 minutes. Legs and lungs burn.

This plan is not personalized for you

This plan uses Power zones (% FTP) and HR zones (% max HR) effort guidance and assumes 12h/week of available training time. Here is what a generic plan cannot account for:

  • All targets are % FTP. Without a recent test, intervals may be miscalibrated.
  • Volume is fixed at 12h/week but your availability changes.
  • Recovery timing may not match your fatigue accumulation.
  • Missed sessions are not recalibrated.
  • No feedback loop from your performance data.

Fueling your training

Gravel nutrition: harder to eat on rough surfaces. Plan for smooth sections. Carry more than you think.

🍌 Before rides

Carb-rich meal 3h before. 100-150g carbs.

⚡ During rides

60-90g carbs/hour from minute 20. Mix gels, bars, real food.

🥛 After rides

1.2g carbs/kg + 20-30g protein within 30 minutes.

💧 Hydration

500-750ml/hour with electrolytes.

🏁 Race day

Pre-ride meal 3h before. Full nutrition plan rehearsed in training.

Gear checklist

Essential

Power meter Non-negotiable for advanced pacing. Without real-time power data, you cannot execute a century pace strategy. Dual-sided power meters provide the most accurate data for detecting imbalances.
Heart rate monitor (chest strap) Secondary effort reference, cardiac drift detection on long rides, and an essential tool for monitoring fatigue and overtraining. Chest straps are required for accuracy at high intensity.
Professional bike fit At 10-15 hours per week and 5+ hour rides, even minor fit issues become injuries. A professional fit optimized for long-distance aero positions is essential before starting this plan.
High-quality cycling bib shorts Premium chamois padding designed for 5+ hour rides. At this volume, invest in two or three pairs to rotate and extend pad life.
Cycling computer with structured workout mode Displays real-time power targets, interval timers, and route navigation. Structured workout mode on devices like Wahoo or Garmin makes executing complex interval sessions simple.
Two water bottles and cages (or hydration system) You need 500-1000ml per hour for 5-6 hours. Two large bottles plus a plan for refills at aid stations.

Nice to have

Aero helmet Saves 30-60 seconds per hour at century pace. Over 5-6 hours, that is 3-6 minutes of free speed without any additional effort.
Race wheels (deep section carbon) Deep section wheels (40-60mm) reduce aerodynamic drag at century pace. The speed advantage compounds over 100 miles. Use in training to ensure comfort and handling.
Saddle bag with spare tube, CO2, and multi-tool Self-sufficiency on 5+ hour training rides is essential. A flat tire 40 miles from home without repair tools ends your session.
HRV tracking device or app Daily HRV measurement helps detect accumulated fatigue before it becomes overtraining. At advanced volumes, this is a valuable early warning system.

5 mistakes that derail advanced plans

1

Overtraining in the build phase

High volume + high intensity without adequate recovery leads to performance decline.

✅ Fix: Monitor HRV and resting HR. If declining, take an extra rest day.

2

Not testing FTP mid-plan

Outdated FTP means wrong zones for every session.

✅ Fix: Retest after every recovery week.

3

Ignoring the taper

Adding volume during taper because you feel good wastes the entire build.

✅ Fix: Trust the plan. The taper makes you faster.

4

Poor race-day nutrition

At advanced intensity, nutrition failures are catastrophic.

✅ Fix: Rehearse exact race nutrition on every long ride over 3 hours.

5

Neglecting recovery between interval days

Back-to-back hard days without adequate fueling and sleep compounds fatigue.

✅ Fix: Easy days must be truly easy: under 75% FTP.

Ride day tips

1

Pace by power, never by feel

Set power targets and stick to them. Race-day adrenaline distorts perceived effort.

2

Train your weaknesses, race your strengths

Use the build phase to address limiters. Use the peak phase to sharpen what you do best.

3

Mental preparation is physical preparation

Visualize race scenarios, practice nutrition under stress, and develop a plan B.

4

Recovery is where gains happen

Sleep 8-9 hours. Fuel recovery rides. The training stimulus means nothing without adaptation.

Why a personalized plan outperforms this one

This plan provides an advanced framework for century preparation. But a plan built from your actual power data, recovery metrics, and weekly schedule adapts to you instead of asking you to adapt to it.

Aspect This plan Personalized plan
Power targets All intervals based on generic % FTP ranges. Without a recent FTP test, targets may not match your actual fitness. ✓ Intervals calibrated to your tested FTP, updated after every test and performance breakthrough. Mid-plan FTP adjustments happen automatically.
Weekly volume Fixed at 10-15 hours per week for every rider. ✓ Adjusted to your real available hours, which can change week to week. Automatically redistributes intensity when volume is constrained.
Recovery timing Recovery week fixed at week 8 regardless of fatigue. ✓ Reads your HRV, sleep quality, and training stress balance to prescribe recovery when your body needs it, not on a fixed calendar.
Missed sessions Plan does not adjust. You fall behind or skip ahead. ✓ Plan recalibrates the following week based on what you actually completed. Prioritizes key sessions when time is limited.
Race-specific preparation Generic century pacing for a flat course. ✓ Adjusts interval profiles, long ride structure, and pacing targets based on your specific race course elevation profile and expected conditions.
Periodization Fixed 4-week base, 7-week build, 3-week peak, 2-week taper for all athletes. ✓ Phase lengths adjusted based on your training history, current fitness, and time to race. Athletes with a strong base may shorten base phase and extend build.
