How to use this race directory

What this directory covers

This directory contains 25 current Half Marathon event listings verified from official event-organizer pages, covering 17 countries. 25 events have a published date; 0 listings are retained with a clear date-to-be-confirmed state rather than guessed or dropped.

Every event guide keeps the official source, verification date, available course or format signals, plan start dates, practical tools and the details you still need to confirm. Search the full list above by event or place. Important links are present in the page source even when the compact list is collapsed.

Choose the event before the plan

Compare date, travel, course or venue demands, entry status and the time you can train consistently. Then use the Half Marathon training hub to choose a realistic runway. A longer plan is useful when it creates gradual foundation work and recovery margin—not when it adds more hard sessions.

The Running-economy strength research separates practical signals from study limits before you turn a benchmark or protocol into training.

What must still be checked

Global directories do not contain every race-week fact. Before entering or travelling, open the official event page and confirm eligibility, start schedule, venue, course maps, equipment, cutoffs, athlete briefing, transport and cancellation terms. Recheck close to race day because organiser details can change.

Training and safety boundary

The guides are educational planning resources. They do not diagnose injury, certify open-water or cycling safety, prescribe an individual medical or nutrition plan, or guarantee a finish. Use appropriate supervision and qualified support for material safety or health concerns.

Adaptive AI coach for iPhone

Meet your adaptive AI coach.

Tell your coach what you are training for. It builds the plan, follows the work you complete, and adapts upcoming training when recovery, your schedule, or real life changes.

FAQs

How many Half Marathon events are in this directory?

The current official-source snapshot contains 25 listings across 17 countries. The source is rechecked before future factual refreshes.

How current are the Half Marathon event dates?

Each listing shows when it was last checked. Time-sensitive details should still be confirmed on the official event page before entry or travel.

How do I choose a Half Marathon event?

Compare runway, course or venue demands, travel, entry status, safety requirements and the weekly training you can actually repeat. Then choose the plan length from current readiness.

Why is an event date marked to be confirmed?

The organiser lists the event but has not published a date. The directory keeps that uncertainty explicit and does not create training start dates until an official date exists.
