Zurich San Sebastián Marathon is Sunday, November 22, 2026. The organizer describes an urban, flat course at sea level through central Donostia. That makes steady pacing plausible, but it does not remove the need to review the current course and race-week conditions.
If the marathon is full, use only the resale path linked by the organizer. Before accepting a transferred place, confirm the official procedure, participant details and deadlines. Do not rely on an informal social-media transfer.
For training, practise sustained goal effort on flat roads but retain turns and small pace interruptions in at least one rehearsal. Confirm the final route, start access, aid and collection venue when the participant guide is published.
Stop and seek appropriate care for severe symptoms or movement-changing pain.
Course + conditions (what should change in training)
- Surface: Road.
- Course difficulty: flat.
Course pacing signals (what to rehearse)
- Road surface: rehearse steady rhythm and fueling at goal effort (not just easy pace).
- Flat profile: practice restraint early; avoid surges and “free speed” that spikes effort.
- Crowds/wind rule: treat headwinds and congestion as “hills” and stay effort-controlled.
