Training Guides

Evidence-based guides for half-marathon runners. Pacing, training structure, race day strategy, and more.

Half Marathon Training Plan: Complete Guide

The short answer: a good half marathon training plan runs 10–16 weeks through four phases — base, strength, speed, and taper — with roughly 80% of your mileage at easy pace and one quality session a week. The exact numbers scale to your goal time and current fitness, but the structure is the same for every runner.

How to Run a Sub-2-Hour Half Marathon

The short answer: sub-2:00 requires averaging 5:41 min/km (9:09/mi), which is realistic for most runners with a 5K time under 27:00 and a 10–12 week plan built around three key sessions — tempo runs, race-pace intervals, and a long run peaking at 18–21 km. Putting in the miles alone isn't enough; the training has to include those specific workouts.

Half Marathon Training on 3 Days a Week

The short answer: yes, three runs a week is enough to train for a half marathon — it's not a compromise, it's a legitimate structure used by working adults who finish in 1:45–2:15. The catch: each of the three runs needs a distinct job (long run, one quality session, one easy run), and you'll want 20+ weeks rather than the standard 12 to get there.

Half Marathon Training for Beginners: Start Here

The short answer: you need 12 weeks, the ability to run 5 km before you start, and a plan that tells you what each session is training — not just how far to go. This guide covers everything a first-time half marathon runner needs to know before they start.

Half Marathon Race Day Strategy: Stop Going Out Too Fast

The short answer: run the first 5 km slower than feels right, fuel before you feel you need to, and trust the pace. Almost every half marathon blowup in the final 5 km was caused by a mistake in the first 3 km. This guide fixes that.

Why You Need to Run Slower to Get Faster

The short answer: running easy (conversational pace, zone 2) builds your aerobic engine without accumulating fatigue, letting you absorb the hard sessions that actually make you faster. Most runners run too hard on easy days and too soft on hard days — this creates a grey zone where nothing improves. Fix the easy days first.

Missed a Training Run? Here's Exactly What to Do

The short answer: one missed run changes nothing. Shift the session if you can, skip it if you can't. Missing a full week means dropping back one week in the plan and continuing — not starting over. Missing two weeks or more means returning to the previous training phase and rebuilding for 1–2 weeks before resuming quality sessions. The plan is more durable than you think.

Half Marathon Training for Busy People

The short answer: three well-chosen runs per week is enough to finish a half marathon. Four is enough to hit a time goal. The problem isn't how many days you can train — it's knowing which sessions to protect and which to sacrifice when the week falls apart. This guide is for runners with a full life who want a specific answer, not a generic plan.

Half Marathon Nutrition Plan: What to Eat and When

The short answer: most runners over-complicate race nutrition. For a half marathon, the main requirements are arriving at the start line well-fuelled, not making any dramatic dietary changes in race week, and deciding whether you'll take on fuel during the race (you probably should if you're running over 90 minutes).

10K to Half Marathon: The Training Bridge

The short answer: if you can run a 10K comfortably, you're closer to half marathon fitness than you think. The gap between the two distances is bridged mostly by extending the long run — not by running faster, or adding complicated sessions. Most runners can complete the jump in 10–14 weeks.

Half Marathon Taper: What to Do in the Final Two Weeks

The short answer: taper by cutting volume significantly (30–40%) while keeping intensity in at least one session. You will feel worse, not better, during taper week — this is normal, expected, and called 'taper madness'. The goal isn't to feel race-ready during taper. It's to arrive at race day with absorbed training and fresh legs.

Running Pace Zones Explained: Easy, Tempo, Speed, and Long Run

The short answer: most recreational runners train almost everything at a medium-hard effort — harder than easy, not quite tempo. This 'grey zone' is the most common reason training plateaus. Pace zones define the specific efforts that produce specific adaptations. Running in the right zone is more important than running more miles.

5K Training Plan: Complete Guide

The short answer: a 5K training plan runs 6–10 weeks — shorter and speed-heavier than half marathon or marathon plans, because the 5K is raced at an intensity much closer to your VO₂max ceiling than to easy pace. Two quality sessions a week is normal (not one), weekly mileage stays modest, and the taper is a few easy days, not weeks.

10K Training Plan: Complete Guide

The short answer: a 10K training plan runs 8–12 weeks — longer than a 5K block, shorter than a half marathon one, because the 10K sits in between on every axis that matters: intensity, mileage, and taper length. It rewards a genuine blend of tempo and speed work rather than leaning hard on either one.

Marathon Training Plan: Complete Guide

The short answer: a marathon training plan runs 16–20 weeks — longer than any other race distance's plan, because the marathon is won or lost almost entirely on aerobic base and long-run durability, not speed. The long run is the anchor of the entire plan, weekly mileage climbs the highest of any distance, and the taper is the longest and most dramatic.

VO₂max and Running Performance: What It Is and Why It Matters

The short answer: VO₂max is the maximum rate at which your body can consume oxygen during exercise, and it sets the ceiling on your aerobic performance — but it's not the whole story. What actually determines your race time at any given distance is what percentage of VO₂max you can sustain, and that percentage is different for a 5K than it is for a marathon. Training paces derived from VO₂max (the VDOT system) account for this; training paces derived from a flat percentage of one pace usually don't.

Marathon Fueling and Carb-Loading: The Science

The short answer: your body stores roughly 1,800–2,000 kcal of carbohydrate as glycogen — enough to fuel about 30–32 km of marathon-effort running before stores run critically low. Carb-loading in the days before the race and taking in 30–60g of carbohydrate per hour during it exist specifically to push that point later, which is why fueling strategy matters far more for a marathon than for any shorter distance.

10K Race Day Strategy: How to Pace It Right

The short answer: warm up properly, start at goal pace rather than faster, and expect the effort to feel hard from kilometre one — because it is. A 10K is raced closer to threshold-and-above effort throughout than a half marathon, which means there's less margin to recover from an over-eager start. Most 10K blowups happen by kilometre 6–7, not in a dramatic final-stretch collapse.
