Official event pageWhat this race demands
This 42.2 km road marathon demands continuous endurance and pacing discipline over the standard full marathon distance.
Aerobic endurance
Covering the full marathon distance of 42.2 km requires a heavily developed aerobic energy system and sustained output over several hours.
Impact durability
Running on paved roads for the entire duration places high repetitive mechanical load on the lower limbs, requiring strong muscular durability.
A sustained effort of this duration requires consistent intake of 60 to 90 grams of carbohydrates per hour to maintain glycogen stores and performance.
