Eighty-four amateur half marathon athletes (168 side feet) in Beijing from October 2018 to May 2021 were recruited, and their age, gender and whether they have foot pain were collected, including 44 males and 40 females, aged from 21 to 60 (40.7±9.3) years. All participants underwent bipedal magnetic resonance imaging (MRI) examinations, and the degree of foot pain was graded by foot ankle injury scale (FASS scale). The relationship between MRI features and the foot pain of amateur half marathon athletes were analyzed. The study found that the proportion of foot pain symptoms among amateur half marathon athletes in Beijing was high(122/168), and the MRI manifestations were mainly heel tendinitis and plantar fasciitis, which accounted for about 59.5% of all cases.招募2018年10月至2021年5月北京地区84例（168侧足）业余半程马拉松运动员，收集其年龄、性别及是否患有足痛等资料，其中男44例，女40例，年龄21~60（40.7±9.3）岁。对所有入组者行均行双足MRI检查，并使用足踝损伤程度量表（FASS分级表）对参与者进行足痛程度分级。分析业余半程马拉松运动员足部疼痛相关的MRI表现特点。研究结果发现北京地区业余半程马拉松运动员中有疼痛症状足者比例高（122/168），MRI表现以跟腱炎和跖筋膜炎为主，这两种表现约占全部病例的59.5%。.
