Choosing a race from this collection
Check the published distance and course format together. A timed challenge with a marathon option and a fixed-distance race have different arrangements. Surface, distance certification, elevation and entry status are separate facts. Follow the organiser’s current information before deciding.
The main half marathons page also keeps races awaiting a next date separate from confirmed editions. An earlier edition is useful context, not evidence of a future date or unchanged route.
