Official event pageWhat this race demands
The Chengdu Marathon requires maintaining a sustained running pace over a full 42.2 km distance on a flat, fast route with minimal elevation change. Athletes must manage efficient pacing to capitalize on the favorable course profile.
Aerobic endurance
Covering the full 42.2 km marathon distance demands deep aerobic conditioning and the physiological capacity to sustain continuous forward locomotion for hours.
Pacing discipline
The flat, fast course profile invites early over-pacing, making strict adherence to a target split essential to avoid late-race deceleration.
Aim for 60 to 90 grams of carbohydrates per hour starting in the first hour to sustain energy output across the marathon duration.
