October 100 is not a race and not a polished event yet. It is a raw idea for a hard, honest day on foot: start on the Montenegro coastline, keep moving, and try to reach 100 km within 24 hours.
The route, date, checkpoints, support, and safety rules are still open. The first job is to understand whether the coastline can provide a practical track and whether enough people want to join responsibly.
This site will collect decisions, route research, notes from test walks, and references from similar 100 km walking events.
