Seeding for 56km
Runner's qualifying times since 1 July in the year prior to the event, are used to seed them: faster runners in the front and slower runners at the back. International runners can use any race since the last Two Oceans Marathon (April 2015).
All Gold & Silver Medallists will be seeded in Group A. Runners wearing Blue and Yellow numbers will be seeded behind the C group unless they qualify for a higher group.
