San Silvestre Ciudad de Guadalajara

The race is run entirely on paved city streets through Guadalajara, which makes it a fast and spectator-friendly route rather than a trail or cross-country course. Full course details and any route map are published on the organiser's event page closer to the date.

Because the course follows the streets of central Guadalajara, spectators can watch from the pavements along much of the route and simply walk between points rather than following a shuttle. The start and finish area is the liveliest spot, with runners passing more than once on the longer course.

San Silvestre races go ahead in cold and wet weather, and cancellation only happens in genuinely unsafe conditions. Any change to the schedule is announced by the organiser on the event page and its social channels, so check those on the morning of the race.
