Holkham Half Marathon

Holkham Half Marathon & 10k (April 2026) is RunThrough UK’s closed-road event set in the grounds of Holkham Hall, Wells-next-the-Sea, Norfolk. Runners choose between a challenging half marathon and a flatter 10k, both on scenic rural roads through parkland with rolling, undulating terrain and elevations around 220m for the half and 97m for the 10k. The course starts and finishes in front of the 18th‑century estate, delivering a memorable atmosphere with enthusiastic marshals and a lively event village.

Perks include chip timing, a unique themed medal, free race photos, post-race goodies, sustainability initiatives, and optional RunThrough Kit T-shirts. Visit the organization's website for the most recent information.
