What this race demands
The Muskoka Marathon requires sustained cardiovascular endurance across 42.2 kilometers on a flat, low-elevation profile designed for speed.
Aerobic Capacity
Sustaining a high running velocity over the full marathon distance demands exceptional aerobic power and efficient pacing.
Musculoskeletal Resilience
Running 42.2 kilometers requires high resistance to repetitive impact forces, particularly given the flat course profile that allows for continuous, unchanging stride mechanics.
A target intake of 60 to 90 grams of carbohydrates per hour is necessary to sustain energy output throughout a marathon duration exceeding two and a half hours.
