Phil Cavell, a veteran cyclist and author, recounts how years of endurance riding masked Mobitz type-II heart block, a dangerous heart‑conduction issue, leading to a hospital stay and the implantation of a pacemaker. He notes that atrial fibrillation is more common in masters endurance athletes and stresses the importance of heart screening (QRISK), moderating extreme training and alcohol, and listening to warning signs. The piece underscores that, with timely diagnosis and care, midlife athletes can return to cycling with greater awareness and safety.
