Check this before entering
The organizer now says all entry recruitment has ended and lists 9 September 2026 at 23:59 as the latest entry cutoff. The older RUNNET route's 6 June deadline was an earlier window, not the final all-channel deadline. The 1.4K run-and-walk is for disability-certificate holders, with a wheelchair-experience option for others; the separate beach walking event is not included.
