Preparing for your first 21.1 km
This page introduces a half-marathon pathway for people with an established running routine. Before choosing a date, consider your recent experience, weekly commitments and time for longer outings. A first half marathon can be about discovering the distance without chasing a time.
Understand the proposed format
The pathway shown covers 10 to 16 weeks with 4 to 6 sessions per week. The sample week illustrates endurance, half-marathon pace, recovery and a long run. These are catalogue guidelines; they do not by themselves determine the programme that fits your situation.
Choose your next step
Compare the 10K pathway if you are still building consistency. If your project is already defined, pace tools help put numbers to a goal and the directory lets you explore available coaching. Every step of preparation counts alongside the finish-line photo.
Your questions
Do I need a time goal for a half marathon?
No. Completing the distance can be your goal. A target time is a separate choice to consider in light of your experience.
