Kiwi Farms

I'm curious what diet or meal plans my fellow Kiwis might be currently using. I'm interested in starting one to offset the fact that my gym has been locked down, and since everything is so fucked right now I decided I should do something other than sit at home and and get fat at my PC.

I'm planning to practice to start running in a 5k, and eventually work my way up to a 10k and then even higher. (Providing they're ever allowed again).
Do you all have any suggestions for any good existing plans, or have any personal diets you've used that have worked well for you?
