Maratona dles Dolomites Training Plan

The Maratona dles Dolomites is widely considered the most spectacular gran fondo in the world — a lottery-entry event that draws nearly 33,000 applicants for roughly 9,000 places each year. The 138-kilometer long course carves through the heart of the Dolomites, crossing eight mountain passes that have hosted the Giro d'Italia for over a century. Riders face consecutive climbs above 2,200 meters, sections at 9–15% gradient, and the ever-present threat of altitude-induced power loss — all before reaching the final test of the Mür dl Giat wall at 19%. Finishing this event is not a matter of fitness alone; it demands months of climbing-specific preparation, a disciplined pacing strategy, and a respect for altitude that riders from sea level cannot shortcut.

Course demands

The Maratona long course stacks eight passes in sequence — Campolongo, Pordoi (2,239 m), Sella, Gardena, Campolongo again, Giau (the crux at 9.3% over 9.9 km, topping 2,236 m), Falzarego, and Valparola — with riders spending extended periods above 2,000 meters where FTP can drop 5–10% due to altitude. The pacing trap is severe: the opening peloton pace is deceptively fast, and anyone who races the first two passes blows up long before the Giau. The final wall, Mür dl Giat, rears up at 19% gradient in the closing kilometers, punishing anyone who has let their fueling slip.

Who this plan is for

Riders who have completed domestic gran fondos and want a structured, science-backed plan to tackle one of Europe's most coveted mountain cycling events.

What makes this plan unique

Back-to-back weekend climbing days; low-cadence strength intervals to simulate 8–15% gradients; extended Zone 2 blocks to build fat-oxidation capacity; altitude-adjusted effort targets for riders training at sea level.

What the plan targets

• Sustained alpine climbing endurance (repeated efforts above 20 minutes at sub-threshold)
• Altitude acclimatization and power management at elevation
• Back-to-back climbing days to build multi-hour fatigue resistance
• Precise FTP-based pacing discipline on long climbs (80–85% FTP target)
• Fueling and hydration execution across 5–9 hours of racing

What you will get

• Progressive long climbing rides that build from 3 hours to multi-hour Alpine simulations
• Zone 2 aerobic base blocks plus targeted threshold intervals on sustained climbs
• Race-week taper protocol and altitude pacing strategy
• Fueling and hydration frameworks tested across long training days
