Date and race-format check
The full marathon starts on Sunday, October 18, 2026, at 7 a.m.; Saturday is for the shorter events. This is an international course, so check the organizer’s current travel-document and border-admissibility requirements before race weekend. Waves leave at three-minute intervals, and the course has a 6.5-hour limit measured from the last-chance pacer. Road reopening is progressive, so plan against the course cutoffs as well as your personal finish estimate.
Course + conditions (what should change in training)
- Surface: Asphalt.
- Course difficulty: flat.
- Climate context: Avg highs ~ 17°C, lows ~ 9°C • Avg monthly precip ~ 87 mm • Avg wet days ~ 15 days.
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.
Climate-specific adaptations (gear + fueling)
- Rain/wet roads: prioritize anti-chafe, socks, and traction; avoid brand-new shoes.
- Fueling rule: practice carbs early and on schedule; do not “wait until you feel it.”
