Frequently Asked Questions
How many weeks should a marathon training plan be?
16-20 weeks is standard for runners who already have a 30-40 km/week base. 12 weeks works if you're coming back from a previous marathon block within the last 12 months. Below 12 weeks risks injury for most runners — a typical phased plan needs ~4 weeks of base, ~6-8 weeks of marathon-specific work, and ~3 weeks of taper. See the 12-week marathon plan if your race is closer.
What's the best marathon training plan for total beginners?
If you can't yet run 5K continuously, do not start a marathon plan — finish couch-to-5K first and add three months of consistent 20-30 km/week before signing up for a marathon. Once you have that base, the first marathon training guide walks through the full 6-9 month progression. Beginners who jump straight from couch to marathon plan have injury rates around 60-70% in the published literature.
How many days per week should I run while training for a marathon?
4-5 running days suits most working adults — three quality sessions (long run, marathon-pace work, intervals or hills) plus 1-2 easy recovery runs. Three days is viable for masters runners or those with high injury risk, but requires near-perfect execution. Six days only helps if your weekly volume is over 80 km. Use the training load calculator to spot weeks that ramp too fast.
Should I train by heart rate or pace?
Both — they answer different questions. Pace zones (Daniels VDOT, derived from a recent race) tell you how fast to run a workout. Heart rate (calculated from your max HR or LTHR) tells you whether your body is responding the way the workout intends, especially on hot days, hills, or fatigue weeks. Most overtrained runners follow pace blindly and ignore HR drift. Most undertrained runners follow HR and never break out of zone 2.
How is RunDida different from a Hal Higdon or Pfitzinger plan?
Higdon and Pfitzinger publish fixed PDFs — same paces and same volume regardless of who downloads them. RunDida pairs every guide with calculators that personalize the numbers: your training paces come from your recent race time, your heart rate zones from your own max, your fueling from your body weight and sweat rate. The reading path here is closer to a curated curriculum than a single plan — pick what fits your current state instead of forcing yourself into someone else's template.
Is it normal to feel exhausted in the last 3 weeks before a marathon?
Surprisingly, yes — "taper crazies" are the documented experience of most marathoners. Reducing volume by 20-50% triggers temporary heaviness in the legs as fluid balance, glycogen, and immune markers reset. The science (Mujika 2003, Bosquet 2007 meta-analysis) is clear: maintain intensity, cut volume, and trust the process. See the marathon tapering guide for the week-by-week prescription.
About these guides
Most marathon training plans on the internet promise the same thing: a PDF, a weekly schedule, a date on the calendar 16 to 20 weeks from race day. They differ in the small print — how much aerobic base they assume you already have, how they treat long runs in the final block, whether they trust heart rate or pace zones, and what they do when life forces you to skip a week.
This category collects 18 guides covering the questions runners actually face: how long a plan should be when you can already run 30-40 km a week versus when you're starting from a brisk walk; whether to follow a Daniels-style VDOT zone structure or a polarized 80/20 model; what tapering should feel like; and how to slot interval work, hill repeats, and core training around a long run that already takes three hours of your weekend. Every guide links the underlying calculator — pace bands, training paces from a recent race time, heart rate zones from a max test — so the theory connects to numbers you can actually run.
Pick a starting point below by your current state. If you've never run continuously for 30 minutes, start at the couch-to-5K plan and ignore the marathon material until you've got three months of consistent running behind you. If you can already cover 25-40 km a week comfortably and have a marathon date 12-16 weeks out, the 12-week marathon plan is the right anchor — read aerobic base building first if your pace feels labored at conversational effort. The marathon tapering guide is the last 3-week block of any plan, regardless of which one you picked.
