“It's more fun than the road. But it's still competition and the rhythm is the same as among the pros”
— Axel Zingle ELITE
“In the US, gravel is a big part of cycling, but in Europe it was kind of a niche discipline. Now, with the UCI World Series and the creation of the UCI World Championships, gravel is growing everywhere. This makes it easier to create access for everybody.”
— Julian Lino ELITE
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.
Plateau Endurance Weather Training Dress RehearsalShed 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.
The course's hardest sustained effort starts at kilometre zero — 450m of climbing in the first 8km, on cold legs.
2,500m of climbing spreads across the Grands Causses plateaus, not one hard hill — repeatable strength matters more than a single effort.
Mid-June in the Aveyron runs warm and bright for a 5+ hour day.
French plateau gravel in Millau Grands Causses.
Wish One Millau is France's sole round of the UCI Gravel World Series and the first-ever UCI gravel event held on European soil (2022). The course opens with the Puech d'Agast climb (450m in the first 8km) straight out of Millau, then spends 130km and 2,500m of climbing across the Grands Causses limestone plateaus before finishing beneath the Millau Viaduct. ~600 riders from 20 nations race it; women 50+ and men 60+ race an official 80km UCI course.
Puncture rates suggest challenging surface conditions, with Rosa Kloser suffering double punctures at km 95 in 2023 and Noah Adhemard forced to DNF from similar mechanical issues.
The 2,500m elevation gain creates consistent selection pressure through rolling terrain. Race reports note "another hard climb awaits between kilometers 30 and 40" following the opening climb out of Millau valley, with the finish featuring a "paved 2km climb" under the viaduct that determines final …
The exact route stays "under wraps until twenty-four hours before the start due to it passing through a military zone," adding mystery to the Larzac military camp access.
Sole French round of the UCI Gravel World Series; ~600 riders from 20 nations. (est. 2022)
A genuinely significant race wrapped in a regional-scale event — the UCI World Series status and the Puech d'Agast opener make it worth targeting for climbers, especially anyone in France or Europe. Not a bucket-list travel race for most Americans, but not just a local fondo either.
Expected Race-Day Conditions:
Climate: French southern summer
Key Challenges: Variable weather, Generally warm, Plateau terrain
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.
Wish One Millau Start Time: Morning start.
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 (81 miles): At ~12mph, expect ~6.8 hours on course. Endurance pace — target 60-80g carbs/hour (405-540g total, or 16-21 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: Puncture rates suggest challenging surface conditions, with Rosa Kloser suffering double punctures at km 95 in 2023 and Noah Adhemard forced to DNF from similar mechanical issues.
Plan your fueling around these conditions — heat and humidity increase fluid and sodium demands significantly.
Aid Stations: Multiple aid stations
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).

Millau has moderate lodging options.
Day before typically
At start/finish
Millau has full dining options. Stock nutrition.
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.
