Training for a Half Marathon:
A 12-Week Plan

The half marathon — 21.1 kilometers — is one of the most rewarding races you can run. It demands real training and endurance, but it's achievable for most runners who are already covering 15–25km per week. In 2026, I won the RAK Half Marathon in the UAE, a race I have great respect for. This 12-week plan is based on the principles I use in my own training and with my coached athletes.

Who Is This Plan For?

This plan is designed for intermediate runners who can already run 5–8km continuously and are running 3–4 times per week. If you're a complete beginner, I recommend starting with the beginner's running guide first and building to 5km before tackling a half marathon program.

The Four Key Training Runs

A solid half marathon program revolves around four types of weekly runs:

• Easy Run (3–4x/week): The backbone of your training. Run at a comfortable, conversational pace. These build aerobic base without overstressing the body.
• Tempo Run (1x/week): A "comfortably hard" effort — faster than easy pace but sustainable for 20–40 minutes. Develops your lactate threshold.
• Long Run (1x/week): The most important workout of the week. Gradually increasing in distance each week, the long run builds the endurance you need to go the distance on race day.
• Speed Work (1x/week, from Week 5): Intervals and strides to improve running economy and race pace ability.

12-Week Half Marathon Training Plan Overview

Pacing Strategy for Race Day

Your race day pacing is critical. The most common mistake in half marathons is going out too fast in the first 5km and struggling in the final 5km. Here's the strategy I recommend:

• Km 1–5: Run 10–15 seconds per km slower than your goal pace. You'll feel like you're holding back — that's correct.
• Km 5–15: Settle into your goal race pace. Find your rhythm and focus on smooth, efficient running.
• Km 15–21.1: If you're feeling strong, gradually increase your effort. The race is won and lost in the final 6km.

"The half marathon is 10km of running and 11km of racing. Get the first 10km right and the last 11km becomes possible."

Strength Training for Half Marathon Runners

Adding 2 strength sessions per week significantly reduces injury risk and improves performance. Focus on:

• Single-leg squats and lunges (glute and quad strength)
• Hip bridges and clamshells (hip stability)
• Calf raises (Achilles and ankle strength)
• Core work — plank, dead bug, side plank

Nutrition During Training

For runs under 60 minutes, water is usually sufficient. For long runs over 75 minutes, you need carbohydrates:

• Take a carbohydrate gel or sports drink every 45 minutes during long runs
• Eat a carbohydrate-rich meal 2–3 hours before your long run
• After your long run, consume protein within 30 minutes to support muscle recovery

The Taper (Weeks 11–12)

The taper period is when many runners panic — they feel sluggish, their legs feel heavy, and they're tempted to train more. Don't. The taper allows your body to fully recover and consolidate the fitness you've built over 10 weeks. Trust the process. By race day, you'll feel fresh and ready.

UAE Half Marathon Calendar

Some of the best half marathons in the UAE and region that you might target:

• RAK Half Marathon (February) — One of the world's fastest half marathon courses, ideal for PB attempts
• Abu Dhabi Marathon (December) — Scenic course around the UAE capital
• Dubai Marathon (January) — Flat, fast, and internationally acclaimed
• Al Mouj Muscat Marathon, Oman (February) — Beautiful coastal course

Completing a half marathon is a genuine achievement that will transform your relationship with running. If you want a personalized program tailored to your specific race, fitness level, and schedule — that's exactly what I offer in my Full Package coaching program.
