100 MCS Green Marathon

Expect a full marathon held in Zürich on a Saturday in early November, so conditions are likely to be cool, possibly wet, and the early morning can be chilly. Plan to arrive with enough time to collect your bib, use the toilets, drop any bag, and reach your start area before it closes. Specific check-in arrangements and start procedures will be confirmed on the organiser's race page closer to the event.

The course marking method has not yet been confirmed. Most road marathons use signage, painted lines, arrows, and marshals at junctions, and sometimes provide a course map. Before race day, study the route map on the organiser's race page, note key landmarks and turns, and consider running a section of the course in advance if you can. Follow the marshals' instructions at all times, especially at junctions and where the route may pass through shared public roads.
