Official event pageWhat this race demands
The MBNA Chester Marathon requires sustaining a continuous running effort over a standard 42.2 km distance across an autumn road course. Athletes must manage glycogen stores and impact fatigue through the full marathon duration.
Aerobic endurance
Covering 42.2 km entirely on foot demands a highly developed aerobic system capable of processing oxygen efficiently over several hours of continuous running.
Impact durability
The repetitive eccentric loading of a full marathon distance requires robust musculoskeletal resilience to maintain running biomechanics through the final miles.
Given a marathon duration typically exceeding 2.5 hours for most runners, aim for an intake of 60 to 90 grams of carbohydrates per hour to maintain blood glucose and spare glycogen.
