UNBOUND GRAVEL 200 TRAINING PLAN.

Unbound Gravel is the world's biggest gravel event — 320km (200mi) across the Flint Hills of Kansas on rocky unpaved roads. Lottery entry, professional field mixed with amateurs, 100mi + 50mi options. Mud years and dust years both exist.

THE OVERVIEW

WHAT THE UNBOUND ACTUALLY IS

TERRAIN

320km of unpaved Kansas backroads — packed dirt with embedded chert (flint) rocks that puncture inattentive tyres. Mostly rolling rather than mountainous; the climbing total is modest but the terrain never lets you settle into a rhythm. Two checkpoints with drop bags split the day into thirds.

WEATHER

Early June in Emporia ranges from 18°C at the 06:00 start to 32-35°C by mid-afternoon, with humidity that compounds the heat. There is almost no shade across the Flint Hills route. Mud years (2015, 2017, 2023) and dust years exist — the same race, very different days, and you don't know which you have until 50km in.

FITNESS DEMANDS

WHAT YOU NEED TO ARRIVE WITH.

MINIMUM FTP

2.6 W/kg

to finish, well-fuelled

COMPETITIVE FTP

3.4 W/kg

to ride the day on your terms

ENDURANCE

12-15 hours/week peaking, with at least two back-to-back weekends of 7-8 hour rides paired with 4-hour days the next morning. You should have done one ride longer than 9 hours before race day, ideally on rough surface. Group-ride experience matters: drafting on Kansas dirt saves 20-25% of your output and is the difference between a 14-hour and a 17-hour finish.

WHY THESE NUMBERS MATTER HERE

Unbound is endurance-limited and tyre-limited before it's FTP-limited. 2.6 W/kg with ultra-trained pacing finishes inside the 21-hour cut-off; 3.4+ W/kg with disciplined fuelling lands you in the sub-12-hour group. Watts win less time at Unbound than smart tyres and a fed gut.

CLIMBING DEMANDS

THE CLIMBS, IN ORDER.

Around 2,800m of climbing across 320km — modest by sportive standards, brutal in context. The Flint Hills are a sequence of short, sharp rollers that never end; you stand, you sit, you stand again, every five minutes for 14 hours. There are no long climbs to settle into and no flat sections to recover on. The relentlessness is the climbing, not the elevation.

TEXACO HILL

KM 50

1.2 km·6.5% avg·78 m gain

The early signature roller. Sets the tone — short, punchy, and there are 200 more of them coming.

LITTLE EGYPT

VARIES

0.8 km·8.5% avg·12% max·68 m gain

Iconic short steep with deep rocky tracks. Pick your line on the way up — wrong line is a hike-a-bike.

CUMULATIVE FLINT HILLS ROLLERS

THROUGHOUT

1 km·5% avg·30 m gain

Most of the day's climbing is rollers under 2 minutes. None of them earn a name; together they're the day. Sit at endurance HR; do not stand and surge on every one.

EXPECTED FINISH TIMES

WHERE YOU'LL LAND.

Use these bands to set a realistic goal. Pick the band closest to your current fitness — not the one above it. Pacing a band you haven't earned is the fastest way to a back-half blow-up.

FIRST-TIME FINISHER

16-20 hours

FTP 2.4-2.8 W/kg, 8-10 hours/week, longest ride 7-8 hours, ultra-pacing experience preferred.

AVERAGE ENTHUSIAST

13-16 hours

FTP 2.8-3.3 W/kg, 10-12 hours/week, multiple 8+ hour gravel rides in training.

STRONG AMATEUR

11-13 hours

FTP 3.3-3.8 W/kg, 12-15 hours/week, gravel-specific terrain, structured tempo work.

ELITE AMATEUR

9-11 hours

FTP 3.8+ W/kg, 14-18 hours/week, racing background, gut trained to 90g+ carbs/hour, comfortable in fast lead packs.

THE TRAINING PLAN

HOW LONG TILL YOUR UNBOUND?

Six weeks-out windows, each built around the demands of this course. Pick the one that matches your window today. The framework is free; coaching makes it personal.

16 WEEKS OUT

BASE PHASE

Aerobic foundation. High volume, low intensity. Don't skip this.

12 WEEKS OUT

LATE BASE

Bridge phase. Volume still rules, but structure begins.

8 WEEKS OUT

BUILD PHASE

Structured intensity enters. Threshold + VO2 max work.

4 WEEKS OUT

PEAK PHASE

Event-specific sharpening. Volume drops, quality rises.

2 WEEKS OUT

TAPER

Sharpness is banked. Now shed fatigue.

1 WEEK OUT

RACE WEEK

Don't do anything clever. Eat, sleep, show up.

FUELLING STRATEGY

EAT LIKE THE DAY DEMANDS.

12-20 hours of riding with no aid stations between checkpoints makes Unbound a logistics problem first. Target 80-100g carbs/hour on the bike; eat additional solid food at each checkpoint (real food beats gels after hour 8). Drop bags at checkpoints 1 and 2 — pre-pack them with bottles, gels, bars, salt tabs, sunscreen, and a fresh kit option for the second half. The Texan rule applies: if you're not peeing every 2-3 hours, you're underfuelled or underhydrated, and either one ends your day. Sodium is the silent killer — Kansas heat sweats out 1,500-2,000mg/hour and you cannot replace that with gels alone. Salt tabs every hour, electrolyte mix in every bottle.

PACING STRATEGY

RIDE IT IN THE RIGHT ORDER.

Unbound is an ultra with a drop bag. Pace at 55-60% of your 4-hour FTP as the all-day ceiling — you do not 'race' Unbound at amateur level, you sit on a controlled effort for 14 hours and let the terrain shape the day. The first 100km is where the front pack rides above your sustainable pace; let them go and ride your watts. Sit in groups whenever you can find them; the Flint Hills cross-tail-headwind sequence makes drafting more valuable here than at any pure road event. Each checkpoint is a 10-15 minute reset — refill bottles, re-grease the chain, swap drop bag, refill jersey, leave. Riders who sit down to chat at checkpoint 1 lose 30 minutes they never get back. The final 100km separates ultra-trained finishers from sportive riders who picked the wrong race.

COMMON MISTAKES

DON'T DO THIS.

Patterns we see at the Unbound every year. Each one has a fix that costs nothing — except the discipline to actually use it on the day.

MISTAKE

Running tyres under 40mm

FIX

42-45mm minimum, with reinforced sidewalls (Panaracer GravelKing SK+, Challenge Gravine Race, Rene Herse Stampede Pass). Tubeless mandatory, with 2-3 plug kits, CO2, and a spare tube. The Flint Hills shred light XC casings inside 50km — there is no recovering from a sliced sidewall at km 80.

MISTAKE

Treating it like a long sportive

FIX

Unbound is ultra territory. Train ultra hours, train your gut to 90g+ carbs/hour, and arrive having done one 9+ hour ride. A road sportive background without ultra pacing is the most common reason for a checkpoint-2 DNF.

MISTAKE

Standing and surging on every roller

FIX

There are 200 rollers and you cannot punch every one. Sit, hold endurance heart rate, and let the gradient do its thing. Surging on rollers is the hidden energy leak that costs people the second half.

FAQ

UNBOUND TRAINING, ANSWERED.

What FTP do I need for the Unbound Gravel?

Unbound is endurance-limited and tyre-limited before it's FTP-limited. 2.6 W/kg with ultra-trained pacing finishes inside the 21-hour cut-off; 3.4+ W/kg with disciplined fuelling lands you in the sub-12-hour group. Watts win less time at Unbound than smart tyres and a fed gut. A practical floor is 2.6 W/kg to finish; 3.4 W/kg to ride competitively.

How long should I train for the Unbound Gravel?

Most riders benefit from 12-16 weeks of structured preparation. 12-15 hours/week peaking, with at least two back-to-back weekends of 7-8 hour rides paired with 4-hour days the next morning. You should have done one ride longer than 9 hours before race day, ideally on rough surface. Group-ride experience matters: drafting on Kansas dirt saves 20-25% of your output and is the difference between a 14-hour and a 17-hour finish. If you have less time, the 8-week and 4-week plans still produce a meaningful result on the right starting fitness.

What's the typical finish time for the Unbound Gravel?

Amateur finishers cover the full range. First-time finisher: 16-20 hours; Average enthusiast: 13-16 hours; Strong amateur: 11-13 hours; Elite amateur: 9-11 hours. The difference between bands is climbing fitness and fuelling discipline more than flat speed.

What's the biggest mistake riders make at the Unbound Gravel?

Running tyres under 40mm. Fix: 42-45mm minimum, with reinforced sidewalls (Panaracer GravelKing SK+, Challenge Gravine Race, Rene Herse Stampede Pass). Tubeless mandatory, with 2-3 plug kits, CO2, and a spare tube. The Flint Hills shred light XC casings inside 50km — there is no recovering from a sliced sidewall at km 80.

How should I pace the Unbound Gravel?

Unbound is an ultra with a drop bag. Pace at 55-60% of your 4-hour FTP as the all-day ceiling — you do not 'race' Unbound at amateur level, you sit on a controlled effort for 14 hours and let the terrain shape the day.

When does the Unbound Gravel take place?

The Unbound Gravel typically runs in June. Count back from your event date and pick the weeks-out plan that matches your window.
