The Alps 2 Ocean Ultra Run is a 7 day, 323km Ultra stage race from the base of Mount Cook to the Pacific Ocean finishing in Oamaru. The race passes by eight lakes, takes in valleys, rivers and diverse terrain and will encounter some of New Zealand's most breath-taking scenery.

The run is broken into 7 stages of varying distances, with the longest stage being approximately 85km to 95km.

There are three entry options.

Participants can choose to be self-supported and will have to carry all their own food, sleeping mat, sleeping bag as well as all compulsory items and any other item you wish to carry for the entire 7 days.

The supported option provides your food and bedding which will be carried for you by the A2O ultra team to the end of each stage. You will still have to carry compulsory gear and food for that day.

Option 3 is a Team option comprising up to 4 runners who must stay within 50 meters of each other for the entire stage. All team members have to run all stages.
