dcterms:description language:enDescription

Previous work (https://doi.org/10.1186/s40798-026-01099-6) estimated the association between race-day air pollution and marathon finishing time using one exposure value per race day across six World Marathon Majors. That design identifies associations from differences between race days but cannot determine how pollution relates to changes in performance within a race. This study will use split times from the London Marathon to examine whether variation in air pollution exposure during the race is associated with within-runner changes in pace. The primary analysis uses a 10-km landmark. The first 10 km are used to characterise demonstrated early-race ability and to predict subsequent passage times. Pace outcomes and cumulative exposure histories are then evaluated from 10 km onwards. Runner data will be linked to hourly spatial air-pollution surfaces generated from London Air Quality Network monitoring sites and predicted along the marathon route at 500-m intervals.
