What this race demands
The Engadin Radmarathon demands sustained high-altitude climbing capacity and resilience across an exceptionally long alpine route spanning five mountain passes.
Climbing volume
Overcoming 4,000 metres of elevation gain across five mountain passes requires sustained power output on long ascents and efficient descending skills.
Endurance capacity
Covering 221 kilometres in the high alpine environment places a heavy demand on aerobic endurance and pacing discipline to avoid early fatigue.
Pass-to-pass pacing
Navigating five distinct mountain passes demands strict energy management throughout the stage to maintain output over many hours in the saddle.
Given the extended duration well beyond 2.5 hours, athletes should aim for a continuous carbohydrate intake of 60 to 90 grams per hour to sustain output across the alpine climbs.
