“The race kicked off at 7am and hits a 1.7-mile road climb at mile 4 to break the field up before descending into the first dirt sector... we tackled the technical single track until I hit a square edged rock and felt my rear tire go soft... took another spill on a rain rutted downhill...”
— Nick Leeper ELITE
“I chose to ride the Enve Melee with 48/35 chainrings, 10-36 cassette, and 35c Pirelli Cinturato Gravel H tires mounted on Zipp 303 Firecrest wheels at 44 PSI. I thought my setup would be quick on the pavement and have enough tire volume to be comfortable on dirt.”

Race-Specific Training Focus:
Distance: 106.5 mi
Elevation: 7,500 ft
Location: Del Mar, California
Signature Challenge: The Muur van Dubbelberg — Double Peak's final mile averages 11% with 20-23% pitches when you've already climbed most of the day's 7,500+ feet. The last 800 feet of elevation come in that brutal final kilometer, forcing riders to 'paperboy' diagonally across the road just to keep moving. Your FTP means nothing here.
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.
Shed 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.
Belgian suffering translated to sunny San Diego, where Double Peak turns roadies into believers and flatlanders into casualties.
The 12,000 ft of climbing includes the notorious Double Peak placement in the final miles. Nick Leeper "couldn't push my target power of 300 watts" on the Double Peak climb, managing only "270 and getting passed more than I should have.
This delivers bucket-list gravel suffering across 23 "unroad sectors" through Southern California terrain. Yun and her partner were "two of just 21 women to finish the Waffle that day. Only about two-thirds of the 300 men finished.
The combination of technical terrain, brutal climbing, and extreme attrition creates unforgettable suffering. Yun described sprinting "between cutoffs" with her partner, "determined to beat the 11:30 a.m. deadline." The weather impact made terrain "pretty rough," adding to the challenge.
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.

Belgian Waffle Ride San Diego Start Time: 7:00 AM. Set your alarm for 4:00 AM.
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 (106.5 miles): At ~11mph, expect ~9.6 hours on course. Lower intensity — fat oxidation increasing — target 50-70g carbs/hour (481-674g total, or 19-26 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: San Diego's May weather typically offers near-ideal conditions, but 2025 proved challenging. "Southern California received a lot of rain this year which rutted out the dirt and made it pretty rough," creating technical terrain issues.
Plan your fueling around these conditions — heat and humidity increase fluid and sodium demands significantly.
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).

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.
