Official event pageWhat this race demands
The Servus Calgary Marathon Race Weekend demands sustained aerobic endurance and pacing discipline to successfully cover the full 42.2 km running distance.
Aerobic Endurance
Covering the full 42.2 km distance requires a high level of cardiovascular capacity and muscular stamina to sustain forward motion over an extended duration.
Impact Durability
The repetitive impact of a marathon-length run places significant mechanical stress on the lower limbs, requiring careful conditioning to resist structural fatigue.
Given the extended duration of a 42.2 km run, athletes should target 60 to 90 grams of carbohydrates per hour to maintain energy availability throughout the event.
