Takes place on Sunday 17 May 2020

The Mammoth Marathon is Norfolk’s first full road race marathon since 1990. The marathon aims to bring people to the North Norfolk coast, highlighting the Council’s Deep History Coast project ultimately boosting the local economy and tourism.

Race Day is Sunday 17 May 2020, all full marathon competitors will set off at 9.30am from the idyllic seaside village of Sea Palling and then follow the coast road through many scenic villages and finishing in Sheringham. There will also be a Half Marathon race taking place on the same day, setting off from Mundesley at 9.30am and finishing at Sheringham High School.

The scenic course passes by outstanding local landmarks such as Happisburgh lighthouse, quaint local churches, the historic Cromer Pier, the site where the West Runton mammoth was discovered plus many areas of Outstanding Natural Beauty and of course the stunning English seaside.

Mammoth Marathon’s road race style allows for many easy access spectator areas so feel free to invite friends and family along to cheer you on.

Both races are being organised by North Norfolk District Council in partnership with North Norfolk Beach Runners and we are all pleased to be working together on such a great project.
