Returning on August 10, 2025, the Altenar Isle of Man Marathon & Half Marathon—sponsored by Altenar through 2027—takes runners on the hilly but beautiful Manx Northern course, a 13.25-mile loop beginning and ending in Ramsey. Half-marathoners complete one lap, while full marathoners run two laps through coastal roads and countryside villages like Bride, Andreas, and St. Jude’s before finishing at Ballacloan Stadium. The event is organized by the Isle of Man Veteran Athletes’ Club under UK Athletics rules and includes chip timing, drink stations every three miles, post-race refreshments, and an event village. Known for its community atmosphere, strong volunteer support, and local enthusiasm, it's consistently ranked among the UK’s most picturesque marathon events.
