Marathon training and workouts

The marathon is an endurance event, so the work is building the endurance to hold your pace for the full 42 km. Speed is a small part of it. There is a reason quick 5 km runners do not automatically run quick marathons: the endurance still has to be built. Most people can already run fast enough. Holding the right pace for long enough is the hard part, and that comes from volume plus time at marathon intensity, sitting on a base of consistency and recovery.

They help, and they make you a more efficient runner. But for the marathon, the thing that pays off most is volume at your actual marathon pace. That is where I would spend the time.

It is a muddled area, with a lot of labels for nearby things. The simple version: the more you train at the pace you want to race, the better, because that is the most specific work you can do. To lift that race pace over time you have to spend some time a little quicker than it, and that is what threshold work is for. You run a touch faster now so you can hold a faster marathon pace later.

Comfortable is the word. If you can hold a conversation, you are about right. Not quite as easy as chatting while you stand still, you can be breathing between sentences, but a proper back-and-forth should be doable. That talk test is the simplest way to stop running your easy days too hard.

Useful as a guide, especially as you start to learn your body. Just know heart rate moves with a lot: a short night, an extra coffee, a cold coming on. Take that into account and do not treat the number as gospel. It works best next to feel and pace, the three together, and a good coach helps you find the zone that is actually yours.

There is no one clean number for this. It comes down to knowing your body and reading a few signals together, feel, heart rate and pace, instead of leaning on any single one. It is a real skill, and a good coach earns their keep here, teaching you to read those signals until you can do it without them.

No. Volume matters and you cannot avoid it, but there is a ceiling, and most people struggle to find theirs. Past a point, more running just buys you injury risk and worse recovery, and that costs you more than the slightly smaller week would have.
