How Much Is a Half Marathon? Distance & What to Expect

You’ve probably heard of a half marathon, but how far is it, and what’s involved? Whether you’re a beginner aiming for your first race or a seasoned runner aiming for a personal best, knowing the distance, pacing, and preparation required is key.

In this guide, we’ll answer the question: How much is a half marathon? And we’ll cover what you need to succeed.

📏 Half Marathon Distance

A half marathon is exactly 21.1 kilometres (or 13.1 miles).
That’s half the distance of a full marathon (42.2km/26.2 miles) — but don’t let the “half” fool you. It’s a serious endurance challenge requiring both speed and stamina.

🔥 Why It’s a Popular Race Distance

Half marathons are ideal because:

• They’re achievable for beginners with structured training

• The distance is challenging but manageable

• Training doesn’t dominate your life like marathon prep

• Races are widely available, from local events to major city runs

🏃 How Long Does It Take to Complete a Half Marathon?

Average finish times:

• Beginners: 2–2.5 hours

• Intermediate runners: 1.45–2 hours

• Advanced/elite: 1–1.5 hours

Your pace depends on training, experience, and race-day conditions.

📅 How to Train for a Half Marathon

A good half-marathon plan includes:

• 3–4 runs per week (mix of long, tempo, intervals)

• Progressive long runs (building to 15–18km before race day)

• Strength training (core, glutes, legs)

• Mobility and stretching

• Fuel and hydration practice

A 10–12 week plan is typical for beginners.

Half-marathon training can lead to fatigue, especially for those balancing work, family, and fitness.
