A trail runner on a grassy ridge above a sea of clouds

A plan for your race. Whatever it is.

Not a catalogue of races we cover. A method that works for the distance you have chosen, at the level you are actually at.

Whatever your level, including none yet

The same method builds a first 10 km and a sub-three marathon. What changes is the starting point, not the care taken. We have no minimum, and no interest in whether you look like a runner.

Every road and trail distance

From 5 km to the ultra, on tarmac, on paths, or a season that mixes both. If it can be run, it can be planned. Other endurance sports are coming — cycling and triathlon are on the roadmap, and we will say so here when they are ready rather than before.

Built on the literature, shaped by your answers

The rules behind your plan come from the published research, read in full and recorded with what it does and does not show. They are applied to what you tell us: your background, your race times, your week, your constraints. Automatic analysis of your watch data is coming soon.

And it fits the life you already have

You tell us the days you can run, the travel, the work, the family. The plan is built on that number of days rather than adapted down from a bigger one. A plan that gets done beats a plan that is optimal.

It moves when you do

A block is not a document you receive once. Each session you log — how it went, how the legs felt, what hurt — feeds the next update of the plan. Miss a week and the plan absorbs it rather than pretending it did not happen.

What we know, and what we don’t

Before you buy anything, read how we think. Our guides separate what the research establishes from what the running world merely repeats — with the sources, including the places where the evidence contradicts the common advice.

Training Easy running: why most of your training should feel slow Nearly every serious runner trains slowly most of the time. The reason is good. The slogans around it are not. Read Training Why runners stop improving — and what actually works Most runners who have stalled are not lazy and not overtrained. They are repeating a week that stopped asking anything of them a long time ago. Read Training Eating and drinking: what’s proven, what isn’t This is where confident advice most often runs ahead of the evidence. Some of it is well tested. Some is opinion wearing a number. And one common habit can kill you. Read

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