Field notes
The homepage sorts guidance by preparation stage, with topics such as police road-use applications, security placement, signage, and heat or medical response. Its examples draw on public specifications: the same 42.195 km distance is paired with markedly different cone counts for the Kochi Ryoma Marathon and Saitama Prefecture Ekiden. The operator identifies itself as Green Cross Co., a safety-equipment seller and rental provider, and says it includes links to its consultation desk.
