The Outlaw Half Holkham Weekend is a premier multi-sport event held annually on the breathtaking Royal Sandringham Estate in Norfolk, offering a unique blend of competitive racing and a family-friendly festival atmosphere. Organized by Outlaw Triathlon, the weekend draws athletes and spectators to its stunning grounds, which provide an inspiring backdrop for all the races and activities. Participants can choose from a diverse range of challenges: the flagship Outlaw Half Triathlon (a 1.2-mile lake swim, 56-mile bike, and 13.1-mile run, with relay options), the swim-and-bike only Outlaw Half Aquabike, and the dynamic Outlaw Gravel Sprint (a 750m swim, 19km off-road bike, and 5km trail run). For those focused solely on running, the weekend also features the scenic Holkham 10K, known for its mix of estate roads and farm tracks, and the Future Outlaw races for children (Mini 1.2 miles, Junior 2.4 miles), ensuring an event for every age and ability level. Beyond the races, the weekend provides onsite camping, an event village with food vendors and exhibitors, and a vibrant social scene, making it a true multisport celebration.
