A half marathon training plan only works if you can actually make it work around your life. The best plan on paper is the wrong plan for you if it tells you to do six sessions a week when you only have room for four, or if it assumes a free Sunday morning that you rarely get. Before you commit to any plan, work through the questions below. They will tell you whether a plan fits, and where you might need to adjust it.
Start with how long you have
Count the weeks between now and your race, and be honest about it. If your race is close, do not try to cram a longer plan into a shorter window. Most people arrive at the start line better off having built up steadily than having rushed the last few weeks.
Two things matter here. The first is your current running. If you already run a few times a week and cover a reasonable distance, you have a base to build from. If you are coming back from a break, from injury, or from illness, you need more time to rebuild before you add in your longer runs or harder sessions. The second is the last week or two before the race, when you reduce your training so you arrive fresh. A plan that keeps the pressure on right up to race day is not setting you up for success.
Compare the weekly commitment to your current schedule
A standard training plan will usually tell you how many days a week it expects you to train. This is the single most common mismatch. A five or six day plan looks impressive, but if you can only reliably protect three or four training days, that is the plan you should be looking at.
Work out your realistic number, not your optimistic one. Count the days you can train without moving something else that matters, like childcare, a shift, or the one evening you keep for yourself. A plan built around the days you genuinely have is one you will finish. A plan built around the days you wish you had is one you will fall behind on by week three, and that is what causes most people to give up.
Look at where the longer runs land too. These take more time than a weekday session, and they usually sit at the weekend. If your weekends are unpredictable, you need a plan you can move around rather than one that assumes the same free morning every week.

Check whether the plan can flex
Life does not run to a training plan. Work runs over, someone gets ill, sleep falls apart for a few nights, and some weeks you simply feel flat. A plan you can adjust is worth far more than a plan you follow perfectly for two weeks and then abandon because life got in the way.
When you look at a plan, ask what happens when you miss a session. A good approach protects the runs that matter most, usually the longer run and one harder session, and treats the rest as flexible. If you are consistently tired across a week, easing or dropping a session and protecting your sleep usually keeps the rest of the week intact. That is a better outcome than pushing through, missing sleep, and losing the following week as well.
Think about the sessions you already do and want to keep, like a regular parkrun on a Saturday or a class you go to with friends. A plan that ignores the the reality of life will not survive contact with a normal week. Build your training around the things you are not willing to give up, rather than trying to fit your life around the plan.
Be realistic about intensity
Most plans mix easier running with harder efforts. If nearly every run is hard, you accumulate fatigue faster than you recover from it, and that is when niggles turn into something that stops you. Easier running is doing real work even when it does not feel like much, so do not be tempted to skip it or speed it up.
If your plan has you feeling worn down week after week rather than gradually stronger, consider whether you need to dial it back. Being tired for a day or two after a hard session is normal. Being tired all the time is a sign the balance is wrong for you.
Know when to stop and ask for help
Aches that ease as you warm up and settle afterwards are part of training. Pain that gets worse as you run, pain that changes how you move, swelling, or a pain that is sharp rather than a general soreness are different, and they are a reason to stop rather than push through. The same goes for training through illness, especially anything that affects your chest or leaves you feverish.
If you are picking up an injury, returning from one, or unsure whether you are well enough to train, speak to a physiotherapist or GP before you carry on, and call the emergency services if something feels serious.
Pull it together
A plan that fits your life is one where the length matches the fitness you are starting from, the weekly days match the days you can actually protect, and there is room to move things when a week goes sideways. Pick for the life you have, keep the sessions that matter most when something has to give, and adjust rather than abandon when you fall behind.
Revay builds a running plan around your real week and adapts it when your reported readiness, sleep, or a life event says it should, rather than expecting you to keep up with a fixed schedule.
