Background  Achilles tendinopathy (AT) occurs in half of the elite runners. AT is a difficult‐to‐treat tendon disease, which may progress from new onset to a chronic state. It is unknown how many runners with new‐onset AT develop persisting symptoms and which prognostic factors are associated with this course.    Objective  To describe how many runners develop persisting symptoms 1 year after onset of reactive AT.    Study Design  Prospective cohort study.    Methods  Runners registering for a Dutch running event (5‐42.2 km) were eligible for inclusion. Runners reporting new‐onset AT between registration for the running event and 1 month after received a 1‐year follow‐up questionnaire. The 1‐year follow‐up questionnaire inquired about persisting symptoms (yes/no), running activity, and metabolic disorders. We calculated the percentage of runners with persisting symptoms and performed a multivariable logistic regression analysis to study the association between potential prognostic factors and persisting symptoms.    Results  Of 1929 participants, 100 runners (5%) reported new‐onset AT. A total of 62 runners (62%) filled in the 1‐year follow‐up questionnaire. Persisting symptoms were reported by 20 runners (32%). A higher running distance per week before new‐onset AT was associated with a lower risk of developing persisting symptoms (odds ratio (OR): 0.9, 95% confidence interval (CI): [0.9;1.0]). There was a positive trend toward an association between metabolic disorders and persisting symptoms (OR: 5.7, 95% CI: [0.9;36.2]).    Conclusion  One third of runners develop persisting symptoms 1 year after new‐onset AT. Interestingly, a higher running distance per week before new‐onset AT potentially lowers the risk of developing persisting symptoms.
