A real cycling coach does five things, week-to-week, that most riders underestimate when they're considering whether coaching is worth it.
First, they design a personalised plan — not a stock plan with your name on it. That means looking at your power profile, your event calendar, your available hours, your strength baseline, your sleep and stress, and your training history, then writing a plan that actually fits your life. Most amateur cyclists fail on plans they couldn't realistically execute; a good coach catches that at the start.
Second, they review your ride files. This is the bit most amateur cyclists most underestimate. Looking at a TrainingPeaks file and seeing what actually happened in a session — power decay, HR drift, cadence patterns, whether the warm-up worked — is where most coaching adjustments come from. A coach who isn't reading your files isn't coaching you.
Third, they periodise around your events. Most amateur cyclists either have no periodisation or are running last year's plan because it 'kind of worked'. A coach builds the year backward from the event calendar — base, build, peak, taper — and adjusts when life intervenes. Fourth, they integrate strength and nutrition into the plan rather than treating them as separate. Fifth, they provide the accountability that consistency depends on. The Roadman What does a cycling coach do article goes deeper, but those five categories are the bulk of the work.
