How to Plan Your Running Season
Having a specific race on the calendar transforms vague intentions — "I want to run a marathon someday" — into concrete, schedulable actions. A well-chosen goal race gives training a purpose and creates a natural checkpoint for measuring fitness progress. The calendar above lists upcoming marathons, half marathons, and major road races worldwide. Filter by continent and time window to narrow your options.
Required lead time depends on target distance and current base fitness. As a general guideline — 5K: 8–12 weeks; 10K: 10–16 weeks; half marathon: 12–20 weeks; full marathon: 16–24 weeks from a solid aerobic base. These windows assume consistent running before the plan starts. Add 4–6 weeks if returning from injury or a long break before beginning structured work.
Most experienced runners structure their season around one or two "A races" — events with a full taper where they target a personal best. Supporting those are "B races" (light taper, fitness test) and "C races" (training runs in a race environment). When selecting your A race, prioritize flat courses, historically good weather for that month, and event organization quality. Most coaches recommend 2–4 goal races per year to allow adequate recovery and continued fitness development between peaks.
How does this work?
How far in advance should I register for a major marathon?
World Marathon Majors (Boston, London, Tokyo, Berlin, Chicago, New York) require registration 6–12 months in advance and most use ballots or qualifying times. Smaller regional marathons typically open 3–6 months out. Booking accommodation early is often more critical than registration timing for popular destination races.
How many races per year is too many?
For marathons: most runners do best with 1–2 per year, spaced at least 16–20 weeks apart. Half marathons: 3–4 per year is sustainable. 5K/10K: up to every 4–6 weeks for experienced runners. Racing too frequently without recovery prevents the fitness adaptations that lead to improvement.
What is the difference between an A race, B race and C race?
An A race is your primary goal event — full taper, fully rested, targeting a PB or specific time. A B race gets a partial taper and serves as a fitness test or confidence builder. A C race is run without any taper as a hard training effort in a race environment, not for time goals.
