This was epitomized in 2019 when British cyclist and Tour de France winner Chris Froome lost control of his bike at 37 mph while wiping his nose, resulting in an admission to intensive care. We aim to produce a comprehensive resource to guide the assessment and management of rhinitis in athletes.</p><p><strong>Design: </strong>Rhinitis is a common condition which can be broadly divided into allergic rhinitis (AR) and non-AR (NAR), a subset of which is known as vasomotor rhinitis. Exercise-induced rhinitis is an important but understudied subcategory of NAR. The pathophysiology of the disease is broadly believed to be an imbalance of the sympathetic and parasympathetic nervous systems, leading to symptoms of watery rhinorrhea, nasal congestion, and paroxysmal sneezing. Up to 50% of people suffer from some degree of EIR, which impedes their nasal breathing and affects performance. The assessment of the athlete with rhinitis requires consideration of both allergic and vasomotor contributions to ensure optimal management is introduced. There is no clear guidance for the management of EIR, with uncertainty regarding the most effective pharmaceuticals and optimizing the timing of treatment to enable peak performance.</p><p><strong>Setting: </strong>N/A.</p><p><strong>Patients/participants: </strong>N/A.</p><p><strong>Interventions: </strong>N/A.</p><p><strong>Main outcome measures: </strong>N/A.</p><p><strong>Results and conclusions: </strong>Based on expert clinical experience in a busy ear, nose, and throat center and a systematic review of current literature, this article proposes a step-wise, incremental approach to the management of EIR symptoms.
