Should I start with a marathon plan?
Review the training you can currently repeat. Begin with a suitable next event and a timeline that allows consistent development. A qualification deadline should not force a jump in training demand.
When should I use a prediction?
After a representative race, with its limitations visible. A short-race equivalent assumes marathon-specific endurance that the result does not prove.
What does the first coaching conversation cover?
Your current activity, past training, practical constraints and the goal behind Boston. We can set a useful nearer target without pretending the final one has a guaranteed date.
Where does this guidance come from?
