I made a video for anyone wanting to get into the 1964 event category. This video has research from the long-time world record holder of the category (me) and can help other runners improve their times as well!

There's also a document for a more detailed guide covering both normal and gold medal categories. https://docs.google.com/document/d/1QIv2M_D07DwMUJ5gUsFH1FOt_-_1VEjjS6gN6JKDeH8/
