Questions

How many weeks to train for a half marathon?

Ten to sixteen weeks. Twelve weeks suits most runners who already run regularly.

Can I train for a half on three runs a week?

Yes. With three runs, each session counts: one quality session, one easy run, one long run.

Is a half marathon plan good preparation for a marathon?

It is a useful step. Many runners race a half six to eight weeks before their marathon.

Your race is on the calendar. Your plan should be too.
