16-Week Intermediate Gravel Training Plan for 100 Miles

Q: Why choose the 16-week plan for a gravel century?

The 16-week plan has the most gradual progression, a 5-week base phase, and a two-week taper. It is best if you are building from a moderate fitness base, want maximum preparation time, or prefer extra buffer for life interruptions. The extended timeline also allows more gravel-specific skill development.

Q: What FTP do I need for a 100-mile gravel century?

There is no minimum FTP. What matters is your ability to sustain a comfortable pace on mixed surfaces for 6-8 hours. The plan teaches you to pace at 76-85% of your FTP, adjusted for surface conditions.

Q: Should I retest my FTP during a 16-week plan?

Yes. Test before starting and again after week 10 (recovery week). With 16 weeks, your FTP will likely improve, and training with outdated zones means every interval is calibrated to the wrong intensity.

Q: How much food should I carry for a gravel century?

Plan for 60-90g of carbohydrates per hour for 6-8 hours. Carry enough to be self-sufficient. Gravel aid stations are less reliable than road events.

Q: Can I do the long rides on road instead of gravel?

No. Long Saturday rides must be on gravel to develop surface-specific skills, nutrition habits, and fatigue tolerance for 100 miles of mixed terrain. Weekday interval sessions can be done on road or indoor trainer.

Q: What tire pressure should I run for a gravel century?

For 40mm tires on a tubeless setup, start around 30-35 psi for a 70kg rider. Over 100 miles, slightly lower pressure reduces cumulative fatigue. Test on training rides before race day.

This 16-week plan prepares intermediate gravel cyclists for a 100-mile gravel century using power and heart rate zones. The extended timeline provides the most conservative and thorough approach, with a 5-week base phase, 7-week build including a recovery week, and a two-week taper. This is ideal if you are building from a moderate fitness base, want maximum preparation time, or prefer extra buffer for life interruptions. The plan builds to a peak long ride of 5 hours before tapering for race day.

Plan overview

Base Weeks 1-5

Extended aerobic base building with sustained Zone 2 gravel efforts. Long rides grow from 2 hours to 3 hours. Weekday rides progress from tempo to sweet spot. The extra weeks allow for a slower ramp and more confidence building on mixed surfaces.

6-8 hours/week

Build Weeks 6-12

Introduce threshold intervals with gravel climb repeats to raise FTP. Long rides extend to 4.5+ hours with sections at gravel century pace. Includes a recovery week at week 10 to absorb accumulated training. Back-to-back long weeks simulate race fatigue.

8-10 hours/week

Peak Weeks 13-14

Highest quality sessions with gravel century simulations and pacing rehearsals. Volume begins to taper but intensity stays high. Your longest ride reaches 5 hours.

9-10 hours/week

Taper Weeks 15-16

Two-week taper with progressive volume reduction. First week cuts volume by 30%, second week cuts by 50%. Focus on sleep, nutrition prep, tire setup, and equipment checks.

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 on gravel.
Z3 Tempo	76-90% FTP	5-6 out of 10	Moderately hard. Sustainable for 30-60 minutes but requires concentration, especially on loose surfaces.
Z4 Threshold	91-105% FTP	7-8 out of 10	Hard. You can sustain this for 20-40 minutes with focus. Speaking is difficult. On gravel climbs, this is your ceiling.
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 on gravel.
Z3 Tempo	71-80% max HR	Moderately hard. Sustainable for 30-60 minutes but requires concentration, especially on loose surfaces.
Z4 Threshold	81-90% max HR	Hard. You can sustain this for 20-40 minutes with focus. Speaking is difficult. On gravel climbs, this is your ceiling.
Z5 VO2max	91-100% max HR	Very hard. Maximum sustainable effort for 3-8 minutes. Legs and lungs burn.

16-week training plan

5 rides per week building from 6h in week 1 to a peak of 10h before a two-week taper. All sessions use power zones (% FTP) with heart rate as a secondary reference. The extended timeline allows for a gradual build to century fitness.

This plan is not personalized for you

This plan uses Power zones (% FTP) and HR zones (% max HR) effort guidance and assumes 6-10h/week of available training time. Here is what a generic plan cannot account for:

All power targets are expressed as percentages of your FTP. If you have not tested your FTP recently, every interval target may be too easy or too hard for your actual fitness level. Test before starting the plan.
Weekly volume is fixed, but your real available time changes week to week. This plan cannot adjust when your schedule shifts.
Gravel surfaces vary enormously. This plan cannot account for your specific local terrain, whether that is packed dirt, loose rock, or sandy double track.
If you miss a session, the plan does not recalibrate. You either fall behind or skip ahead, and both compromise the training progression.
There is no feedback loop. This plan does not read your power data, sleep quality, or HRV to adjust intensity. An AI coach does this automatically every week.

Week-by-week breakdown

Week 1 Base 🕐 5h 55min

Gentle gravel century start

Focus: Establish the 5-ride weekly structure with conservative volume. Long ride at 2 hours.

Key session: Saturday long gravel ride: 2h at Zone 2 (56-75% FTP). Focus on smooth pedaling and relaxed grip.

What to feel: Easy and controlled. This week is about building the habit, not building fitness.

Avoid: Riding too hard in week 1. The sessions should feel easy. That is the point of a 16-week build.

Week 2 Base 🕐 6h 15min

Gravel aerobic foundation

Focus: Extend tempo blocks to 8-10 minutes. Long ride reaches 2h 15min.

Key session: Saturday long gravel ride: 2h 15min at Zone 2. Stay disciplined on power, no surges.

What to feel: Controlled and comfortable. Building the base for harder work ahead.

Avoid: Pushing too hard on loose gravel sections. Let the bike move beneath you.

Week 3 Base 🕐 6h 35min

Tempo extension

Focus: Tempo blocks reach 10-12 minutes. Long ride at 2h 30min.

Key session: Tuesday: 3x10min mixed-surface tempo at 76-90% FTP. Steady power on gravel.

What to feel: Tempo should feel moderately hard but sustainable.

Avoid: Starting tempo intervals too hard and fading in the final interval.

Week 4 Base 🕐 7h

Sweet spot introduction

Focus: First sweet spot intervals at 88-93% FTP. Long ride at 2h 45min.

Key session: Thursday: 2x12min sweet spot at 88-93% FTP. Practice eating on the Saturday ride every 30 minutes.

What to feel: Sweet spot should feel genuinely hard. The long ride should feel solid but not depleting.

Avoid: Waiting until you feel hungry to eat on long rides.

Week 5 Base 🕐 7h 30min

Sweet spot extension and tempo finish

Focus: Sweet spot blocks extend to 15 minutes. Long ride at 3h with a tempo finish.

Key session: Saturday: 3h with the last 30min at tempo. This teaches you to push when tired.

What to feel: The tempo finish should feel hard after 2.5 hours of gravel riding.

Avoid: Confusing sweet spot with threshold. Sweet spot is 88-93%, not 95-105%.

Week 6 Build 🕐 7h 50min

Gravel climb repeats begin

Focus: First gravel climb repeats at 91-105% FTP. Century pace sections on long ride.

Key session: Thursday: gravel climb repeats, 3x8min at 91-105% FTP. Stay seated for traction.

What to feel: Threshold should feel hard. Speaking is difficult.

Avoid: Standing and surging on every gravel climb. Stay seated for traction and energy conservation.

Week 7 Build 🕐 8h 30min

Century pace practice

Focus: Long ride at 3h 30min with century pace sections. Climb repeats extend to 10 minutes.

Key session: Saturday: 3h 30min with century pace at 76-85% FTP. Practice race-day nutrition.

What to feel: Century pace should feel like controlled tempo on gravel.

Avoid: Tire pressure too high. Lower 5-10 psi below your road setup.

Week 8 Build 🕐 8h 55min

Threshold extension

Focus: Climb repeats reach 15 minutes. Long ride at 3h 45min with century pace.

Key session: Thursday: 2x15min gravel climb repeats at 91-105% FTP. Hold even power.

What to feel: Hard but manageable. If you cannot complete both intervals, your FTP may need retesting.

Avoid: Burning matches on gravel climbs. Pace conservatively.

Week 9 Build 🕐 9h 35min

Volume peak

Focus: Highest volume week. Climb repeats at 20 minutes. Long ride at 4 hours.

Key session: Thursday: 2x20min gravel climb repeats at 91-105% FTP. This is the hardest interval session.

What to feel: Tired by Thursday but capable by Saturday.

Avoid: Gripping the handlebars too tight on rough descents. Relax your hands.

Week 10 Build 🕐 5h 40min

Recovery week

Focus: Reduce volume by 40%. Easy rides with a short tempo session. Let your body absorb the training.

Key session: Thursday: easy ride with 2x10min tempo. Just enough to stay sharp.

What to feel: Fresh, motivated, and slightly restless.

Avoid: Panicking about losing fitness. You are absorbing it, not losing it.

Week 11 Build 🕐 9h 30min

Return to intensity

Focus: Return to high volume. Long ride reaches 4h 15min with century pace.

Key session: Saturday: 4h 15min with century pace sections. Simulate race conditions.

What to feel: Strong and confident after recovery week.

Avoid: Going harder than planned because you feel strong. Save the energy.

Week 12 Build 🕐 9h 45min

Final build

Focus: Last high-intensity build week. Long ride at 4h 30min with century pace.

Key session: Thursday: 2x20min gravel climb repeats at 91-105% FTP. The last hard threshold session.

What to feel: Hard but completable. Your body has adapted over 12 weeks.

Avoid: Adding extra volume because you feel you should do more with 4 weeks left.

Week 13 Peak 🕐 10h

Century simulation

Focus: Century simulation: 2x30min at century pace. Longest ride of the plan at 5 hours.

Key session: Saturday: 5h gravel ride with century pace rehearsal. This is your dress rehearsal for the distance.

What to feel: Hard but doable. If you can complete 5 hours on gravel with good pacing, you are ready for 100 miles.

Avoid: Treating the simulation as a time trial. It is a pacing exercise.

Week 14 Peak 🕐 7h 30min

Sharpening

Focus: Volume drops but intensity stays. Long ride reduces to 3h 30min with pace rehearsal.

Key session: Saturday: 3h 30min with the last 45min at century pace. Final long effort before taper.

What to feel: Sharp, fast, and efficient. Rides feel easier at the same power.

Avoid: Adding extra intensity because you feel good. The taper makes you feel strong.

Week 15 Taper 🕐 5h 55min

Pre-race week

Focus: Volume drops by 30%. Shorter sessions with some tempo and sweet spot to stay sharp.

Key session: Saturday: 2h 30min easy gravel ride. Final dress rehearsal for tire pressure and nutrition.

What to feel: Fresh and slightly restless. Legs should feel light and responsive.

Avoid: Doing a long hard ride the week before race day. Trust the taper.

Week 16 Taper 🕐 ~5h (including race)

Race week

Focus: Two short rides to stay loose. Tuesday easy tempo, Thursday activation. Saturday is century day.

Key session: Saturday: 100-mile gravel century. Start at Zone 2, build to century pace by mile 20, eat on smooth sections every 20 minutes.

What to feel: Restless, eager, and slightly nervous. Trust the 15 weeks of work behind you.

Avoid: Going out too fast in the first 20 miles. Gravel century pacing is everything.

Fueling your training

Gravel century nutrition is the hardest challenge in endurance cycling. Rough surfaces make it harder to eat and drink, aid stations are sparse, and 6-8 hours of variable effort on mixed terrain demands more fuel than the same distance on pavement.

🍌 Before rides

Eat a carb-rich meal 3 hours before longer rides. Aim for 100-150g of carbohydrates: rice, oatmeal, toast with honey, or pasta. For early morning rides, a smaller meal of 60-80g carbs 90 minutes before is sufficient.

⚡ During rides

For rides over 90 minutes, aim for 60-90 grams of carbohydrates per hour. On gravel, plan your eating for smooth sections where you can safely reach into your frame bag. Start eating at minute 20. Carry more food than you think you need for 100-mile gravel events.

🥛 After rides

Within 30 minutes of finishing, consume 1.2g of carbohydrates per kilogram of body weight plus 20-30g of protein. Good options: recovery shake, rice with chicken, chocolate milk, or yogurt with granola and fruit.

💧 Hydration

Drink 500-750ml per hour depending on temperature and sweat rate. Use electrolyte mix in your bottles. Carry at least two large bottles plus extra in your frame bag. Know where water stops are on the course.

🏁 Race day

Eat your pre-ride meal 3 hours before start. Carry enough nutrition for 6-8 hours: budget 60-90g carbs per hour. Pack everything in your frame bag and top tube bag. Know where aid stations are. Carry backup nutrition. Never try new food on race day.

Gear checklist

Essential

Power meter Essential for pacing a gravel century. Without power data, you risk blowing up after mile 60 when fatigue amplifies every surface imperfection.

Heart rate monitor Secondary effort reference and cardiac drift detection. Over 6-8 hours, cardiac drift becomes significant and heart rate helps you recognize when to back off.

Gravel bike with drop bars A gravel-specific frame with tire clearance, compliance, and multiple hand positions is essential for 6-8 hours on mixed surfaces.

Wide tires (38-45mm) with appropriate tread Wider tires at lower pressure provide the grip, comfort, and confidence needed for 100 miles of mixed-surface riding.

Tubeless setup with sealant Tubeless tires seal small punctures automatically. Over 100 miles of gravel, the probability of debris encounters is near certain.

Frame bag or top tube bag Carries nutrition, tools, and spares for a self-supported 100-mile effort. On gravel, you need everything accessible without stopping.

Nice to have

GPS computer with route loaded Displays real-time power, heart rate, distance, and route navigation. On a 100-mile gravel course, knowing what is ahead prevents pacing mistakes.

Tire plug kit, spare tube, and CO2 inflator Over 100 miles, carry backup for your backup. A plug kit, a spare tube, and two CO2 cartridges cover most scenarios.

Padded bar tape or ergonomic grips Reduces hand and arm fatigue from vibration. Over 100 miles of rough surfaces, hand fatigue becomes a serious limiter.

5 mistakes that derail intermediate plans

Running tire pressure too high for gravel surfaces

High tire pressure reduces grip, increases vibration, and leads to faster fatigue. Over 100 miles, the cumulative effect of wrong pressure is devastating.

✅ Fix: Lower tire pressure 5-10 psi below your road setup. For 40mm tires, start around 30-35 psi and adjust based on your weight and surface conditions.

Burning matches on gravel climbs in the first half

Gravel climbs often take longer than they appear. On a century, every surge above threshold in the first 50 miles costs you double in the second 50.

✅ Fix: Cap gravel climb efforts at 105% FTP for the first 60 miles. Stay seated for traction. Save your matches for the final 20 miles.

Hand and arm fatigue from gripping too tight

Over 6-8 hours, tight grip leads to hand numbness, forearm pump, and shoulder tension that can force you to stop.

✅ Fix: Consciously relax your grip every 10 minutes. Move hand positions frequently. Consider padded bar tape and gel pads.

Not carrying enough nutrition for the full distance

Gravel centuries have fewer aid stations than road events. Running out of food at mile 70 on a remote gravel road is race-ending.

✅ Fix: Carry enough nutrition for the full distance. Budget 60-90g carbs per hour for 6-8 hours. Use a frame bag to carry backup food.

Ignoring surface transitions in pacing

Power that feels sustainable on pavement becomes unsustainable on loose gravel. Over 100 miles, failing to adjust leads to early fatigue.

✅ Fix: Reduce power by 5-10% when transitioning from pavement to loose gravel. Let heart rate confirm your adjusted effort is in the right zone.

Ride day tips

Pace the first 30 miles conservatively

On a gravel century, the race starts at mile 50. Set a power ceiling of 80% FTP for the first 30 miles regardless of how easy it feels.

Eat on smooth sections, plan for rough ones

Know the course surface profile and plan nutrition for smooth sections. Carry easy-to-open food in your top tube bag. Practice on every training ride.

Lower tire pressure and trust it

Lower pressure means more grip, more comfort, and less fatigue. The comfort savings compound over 6-8 hours of mixed-surface riding.

Break the century into segments mentally

Do not think about 100 miles. Think about the next aid station, the next 10 miles, the next climb. Mental fatigue on gravel is amplified by surface difficulty.

Why a personalized plan outperforms this one

This plan provides a solid framework for gravel 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.
Weekly volume	Fixed at 6-10 hours per week for every rider.	✓ Adjusted to your real available hours, which can change week to week based on life and work.
Surface specificity	Generic gravel instructions that may not match your local terrain.	✓ Sessions adapted to your specific race course surface profile and local training terrain.
Missed sessions	Plan does not adjust. You fall behind or skip ahead.	✓ Plan recalibrates the following week based on what you actually completed.
Race-specific preparation	Generic gravel century pacing for a typical mixed-surface course.	✓ Adjusts interval profiles and long ride structure based on your specific race course profile and surface breakdown.
