North Norfolk’s Mammoth Marathon returns for 2023 with runners set to tackle the coastal route in a full, and half marathon.

The event was scheduled to run on Sunday 21 May 2023.

The Council has taken the decision to move the event one week forward after receiving notification of a coinciding event in the area  and to protect runners while they compete in the road race.

The new date for the Mammoth Marathon is Sunday 14 May 2023

Tickets are available via Race Roster
