“Around mile 42, I was coming down a descent, trying to stay slower, but still moving faster than I should have been. As I bounced across the bottom, I suddenly found my wheels spinning and realized that I had dropped my chain. I pulled over to the side and climbed off my bike...”
— Caroline Worrall RECREATIONAL
“Another enormous choice was using Silca chain wax. I've been on the wax train for a few years now and I'll never go back. The mud was just enough to spray a film over the drivetrain but a quick power wash fixed that issue and there was no need to re-lube. Just wipe and go.”

Race-Specific Training Focus:
Establish aerobic foundation. 70-85% volume in Z1-{{Z2}}. {{CTL}} rising steadily (+5-8/wk in loading weeks, netting about +10/month after recovery weeks). {{TSB}} slightly negative (-5 to -15). Week 4 = recovery week (60% volume). Feels boring but doable—you should finish most rides feeling like you could do more.
Layer intensity, develop race-specific fitness. 60-70% Z1-Z2, 30-40% Z3-Z6. Two to three quality sessions per week. The magic happens here: deliberately dig a fatigue hole ({{TSB}} goes to -25), recover just enough, then dig another hole. This is where fitness sharpens.
Heat Training Dress Rehearsal Aggressive Fueling Robust TaperShed fatigue, maintain sharpness. Volume drops 30-50%. Intensity stays high but duration decreases. Week 11: {{TSB}} rises to +5 to +10. Week 12: TSB targets +15 to +25 for race day. Fitness doesn't improve—the goal is to remove the fatigue layer so you can express the fitness you've built.
Gravel GritHeat adaptation takes 2-3 weeks. Starting too late means racing unprepared in dangerous conditions.
Technical skills prevent crashes and save energy. Poor handling wastes watts and increases risk.
This tests nutrition, pacing, and mental preparation. Skipping it means discovering problems on race day.
The gravel race by which all others are measured.
Unbound is gravel racing's Mount Everest—not because it's the hardest course, but because it's the race that defines the sport. Riders don't 'do' Unbound casually. They plan for it, obsess over heat protocols, and show up knowing that crossing the line in Emporia means something. The course itself isn't new—rolling terrain, gravel, heat. What makes it legendary is the field, the atmosphere, and the weight of the finish line. If you finish Unbound, you've earned it.
Kansas June weather can move from a clear forecast to "some of the worst rain I have ever pedaled through" in two hours. Other editions deliver a merciful "cool 65 degrees." Heat, wind, storms, and wheel-stopping mud all belong in the plan.
Recent routes total roughly 11,000 feet across Flint Hills rollers, which scores 5 under the published elevation rubric. The final 2027 route is pending, so that figure is a planning reference rather than an edition-specific promise.
Support crews can reach only four spots across 200 miles of remote ranch roads. When the heat lands, there are "lots of people pulled over in the shade trying to rest or shake out cramps.
The Ironman of gravel. Finishing earns respect. Winning earns legend status. (est. 2006)
If you're serious about gravel, you'll do Unbound eventually. Whether you finish smiling or swearing, you'll never forget it.
Expected Race-Day Conditions:
Climate: Flint Hills heat
Key Challenges: Heat adaptation critical, Hydration demands extreme, Sun exposure relentless
60-90 minutes Z2 endurance. Keep legs moving, nothing hard. Optional: 3 × 1 min Z4 to keep neuromuscular system awake.
45-60 minutes Z2. Maybe 2 × 3 min G Spot if you're feeling restless. Don't go hard.
Rest day or 30-45 minutes very easy spin. The last hard workout was 4-5 days ago. Everything now is just maintenance.
45-60 minutes Z2. Include 3-5 × 30 seconds Z5-Z6 (openers to keep legs sharp). Last real ride before race.
Travel day (if traveling) or rest day. Optional 30-minute easy spin if legs feel heavy.
30-45 minutes Z2 with 3 × 1 min Z4 openers. Course preview if racing Sunday. No heroics.
20-30 minutes very easy spin or complete rest. Do what's worked for you previously.

Other: Sunscreen, chamois cream, arm warmers/vest, rain jacket (if forecast), extra base layer.
Race essentials: Bib number and pins, race chip, ID and emergency contact info.
Unbound Gravel 200 Start Time: Saturday; final 2027 start time pending.
Wake up. Coffee if you normally drink it (not the time to change habits). Breakfast: 100-150g carbs, minimal fat, minimal fiber. Oatmeal with banana and honey, bagel with jam, or white rice with a pinch of salt.
Start sipping sports drink. Begin hydrating and topping off fuel. Apply chamois cream and sunscreen.
Arrive at start area. Check in, use porta-potty. Get your head right.
Light warmup ride: 10-15 minutes easy spinning. Wake up the legs.
Final gear check: bottles filled and secured, nutrition in pockets, tire pressure verified, drivetrain sounds good. Run through your performance statements mentally.
Openers near the start: 2-3 x 30 seconds at race effort with easy spinning between. Gets HR up, legs awake, reminds body what fast feels like.
Roll to start line. Find your position. Deep breath.
6-2-7 breathing if anxious. You're ready. Trust your training.
Your Fueling Math (200 miles): At ~10mph, expect ~20.0 hours on course. Survival pace — palatability and GI tolerance are the limiters — target 30-50g carbs/hour (600-1000g total, or 24-40 gels).
Carb targets scale with duration: shorter races burn more carbs per hour at race intensity, while ultra-distance events shift toward fat oxidation and GI tolerance becomes the limiter (Jeukendrup 2014, van Loon et al.).
Enter your details for a complete race fueling plan — carbs, hydration, sodium, and an hour-by-hour strategy.
Your numbers are the easy part.
Hitting them at race intensity is a trained skill — gut training over 4-6 weeks, bottle logistics, heat adjustments when the plan meets the weather. The custom training plan builds your fueling protocol into the actual training weeks, so race day is a rehearsal, not an experiment.

What Riders Say About Conditions: Kansas June weather can move from a clear forecast to "some of the worst rain I have ever pedaled through" in two hours. Other editions deliver a merciful "cool 65 degrees." Heat, wind, storms, and wheel-stopping mud all belong in the plan.
Plan your fueling around these conditions — heat and humidity increase fluid and sodium demands significantly.
Aid Stations: Final 2027 checkpoint plan pending. The official rules page currently describes designated checkpoints and water oases for the 200-mile race.
2-3g carbs/kg bodyweight. Low fat, low fiber. Familiar foods only. 500ml water with meal.
One gel (24g carbs) with 200ml water. Tops off blood glucose.
Focus on pacing, positioning, settling in. Sip on drink. Heart rate is spiking, gut blood flow is reduced.
First gel or equivalent (24g carbs). Start your fueling clock. Hydrate consistently.
Consume carbs consistently by the clock. Target rate depends on race duration: 80-100g/hr for races under 4 hours, 60-80g/hr for 4-8 hour events, 50-70g/hr for 8-12 hours, and 40-60g/hr for ultra events (12+ hours). At lower intensities fat becomes your primary fuel and GI tolerance is the limiter. Set a timer. Your brain will be stupid. It will forget to eat.
Practice eating real food on easy rides. Start with 40-50g carbs per hour, mostly solid. Build tolerance gradually. SGLT1 transporters can double in 2 weeks of consistent gut training (GSSI).
Increase toward your race-day target rate. Mix of liquids and solids. Practice eating at tempo pace. Your gut adapts to what you train it for.
Hit your race-day target rate (see duration-scaled targets in your prep kit). Race nutrition only (gels, drink, bars you'll use on race day). Practice at race pace. For ultra events (12+ hours), include savory and mixed-macro foods alongside gels.
Stick with what worked in training. No new products. Trust your gut (literally).
Known Suffering Zones:
Budget Planning:
Entry Fee: ~$345
Cost of Trip: Above average (4/5)
Nearest Airport: Wichita (ICT) - 90 minutes to Emporia
Wichita (ICT) - 90 minutes to Emporia
Book 12+ months early. Prioritize proximity to start line over charm. Emporia hotels sell out. Expect $150-250/night for basic rooms.
Friday at Emporia State University. Long lines. Budget 45+ minutes.
Free lots open 4:00 AM. Arrive early or walk 15+ minutes.
Pack your own breakfast. Race-morning lines are absurd. Stock up at Walmart/Dillons day before.
Spin in Z1 after crossing the finish line. Let heart rate drop gradually. Stopping abruptly causes blood to pool in your legs.
20-30g protein, 60-100g carbs, 500-750ml fluid with electrolytes. Chocolate milk, protein shake with banana, or whatever the finish line has.
You lost 1-4 liters of fluid. Drink 500-1000ml within the first hour. Add electrolytes. If pee is dark yellow by evening, keep drinking.
