We read your running before we write a session.
Give us one recent run. We’ll tell you what you can race, build the plan to get you there, and stay with you to the line.
I read your last few weeks before I touch a single session. The plan has to fit the runner in front of me, not the other way round.
One read. Every step that follows fits the same runner.
