The Firenze Marathon is a major annual road running event that takes participants on a 42.195 km course through the historic center of Florence, starting and finishing near the Duomo.
What this race demands
The Firenze Marathon requires sustaining continuous forward locomotion for 42.195 km on city streets through the historic center of Florence in late autumn.
Aerobic Endurance
Covering the full marathon distance of 42.195 km places heavy demands on the aerobic energy system and muscular endurance over several hours of continuous running.
Impact Durability
The flat elevation profile of only 85 meters means the course is relentless in its repetitive running mechanics without significant climbs or descents to alter muscle recruitment.
Late-Autumn Thermoregulation
Staged in November in Florence, the event demands appropriate management of cool starting temperatures that rise moderately during prolonged exertion.
A continuous carbohydrate intake of 60 to 90 grams per hour is required to sustain energy output across the full duration of the marathon.
