The organizer built Del Fuego around a point-to-point ride through Chilean Patagonia rather than a repeated festival circuit. The 2027 event is presented as the fourth edition. Founded in 2024. By Tito Nazar and Áspero SPA.
Reputation: An emerging international ultra with a small field and an unusually ambitious route.

A non-stop, single-stage Patagonian crossing with mandatory controls, organizer aid, no private outside assistance, and open-road exposure.
Signature challenge: Keeping equipment, navigation, fueling, sleep, and judgment intact from Puerto Natales through the ferry crossing and the final remote road to Caleta María.

From the Field
The event features a sprint loop of 252 km and a 1000k race, both showcasing the stunning landscapes of Patagonia.

Patagonia is very far south, close to Antarctica maybe indeed I think it's the farthest South I've been.

3 WORKOUTS BUILT FOR THIS RACE
Each workout below is selected from our archetype library based on Del Fuego Race’s specific demands. Click any workout to see the full execution protocol.
DurabilityProgressive Fatigue
2hr+
Power targets INCREASE as duration goes on — reverse-pacing that builds race-finishing strength.
652 miles. Your legs will beg to quit after 120. This trains the power output you need from mile 130 onward.
EXECUTIONEach block is harder than the last. By the time you hit threshold, you’ve been riding for 80+ minutes. The final VO2 effort is the test — can you go HARD when everything says stop? This is how you win the last 20 miles of a gravel race.
HEAT PREP April in Puerto Natales to Caleta María, Magallanes, Chile — April reduces the usual summer wind but does not remove exposure to cold, wind, rain, snow, and fast weather changes. Begin heat acclimatization 10–14 days before Del Fuego Race — 20–30min sauna sessions or midday rides in full kit. Pre-load sodium 48 hours out. Target 500–750ml/hr with electrolytes on race day.
NUTRITION Ultra-distance fueling for 652 miles: 80–100g carbs/hour from mile 1 — don’t wait until you’re hungry. Practice your exact race-day nutrition in every long training ride. Carry backup calories. 652 miles burns 8,000–12,000+ calories — you cannot replace them all, but you must try.
TERRAIN Mixed terrain at Del Fuego Race requires surface adaptability. Include weekly rides on patagonian mixed-surface ultra to build confidence. Expect: patagonian gravel roads, public roads with traffic, pampas and forest tracks.
EnduranceTerrain Simulation Z2
2hr+
Zone 2 with rolling terrain simulation — undulating power that builds fat oxidation.
Every hard session works better with a bigger aerobic base. At 652 miles, base fitness is the difference between racing and surviving.
EXECUTIONStay in Zone 2 the entire time, but undulate your power to simulate rolling terrain. The rises push the top of Z2; the valleys ease off. This builds terrain-responsive pacing without leaving the aerobic zone. Your body learns to modulate power without thinking.
POWERRises: 72–78% FTP | Valleys: 62–68% FTP | All within Zone 2
CADENCERises: 80–85rpm | Valleys: 88–92rpm
POSITIONAlternate: hoods on rises, drops on flats. Build position endurance.
RPE3–4 throughout — never hard, but never mindless

HVLI ExtendedBack-to-Back Long
2.5hr + 2hr+
Saturday long ride, Sunday medium ride — back-to-back volume that mimics multi-day fatigue.
652 miles rewards fat oxidation. This volume work shifts your fuel mix so you're still burning fat at hour 5, not bonking at hour 3.
SAT: Z2 2.5hr
SLEEP
SUN: Z2 2hr

STRUCTURESaturday: 2.5hr Zone 2 | Sunday: 2hr Zone 2 with 3×5min tempo inserts
EXECUTIONSaturday loads the fatigue. Sunday tests your ability to ride steady on tired legs. The Sunday tempo inserts at minutes 45, 75, and 105 simulate the surges you’ll face late in a race when your legs are already cooked. This is durability training.
POWERBoth: 65–70% FTP | Sunday tempo: 76–82% FTP
CADENCESaturday: 85–90rpm | Sunday: 85–90rpm, 90–95rpm on tempo inserts
POSITIONBoth days: rotate positions. Sunday tempo inserts in drops.

The Haín regulation requires winter gloves, waterproof layers, insulated clothing, and an emergency system while explicitly naming winds above 100 km/h, snow, storms, and hypothermia among accepted risks. Multi-day autumn exposure at this remoteness meets the rubric's extreme-climate band.[1]
How are the logistics for Del Fuego Race?
+
Haín starts in Puerto Natales, crosses the Strait of Magellan, finishes on the remote road at Caleta María, and then requires organizer extraction to Porvenir plus onward ferry travel. Medical facilities can be more than seven hours away, so this meets the rubric's extreme-remoteness threshold.[1]
How adventurous is Del Fuego Race?
+
Haín links Torres del Paine, Pali Aike, the Strait of Magellan, Tierra del Fuego, Pampa Guanaco, Lago Fagnano, and the final road to Caleta María. A mandatory 1,050-kilometer line through those places earns the rubric's bucket-list adventure score.[7]
How prestigious is Del Fuego Race?
+
The organizer calls 2027 the fourth edition, and the event has international riders and specialist bikepacking coverage, but it remains young and outside the established global championship or marquee-ultra tier. Local-to-emerging recognition is a two.[1]
Should I race Del Fuego Race?
+
Yes, if your ultra systems are already proven and you want the logistics, weather, and isolation to be part of the test. No, if this would be your first unsupported overnight ride.
