Training for Your First Half Marathon: A Practical 12-Week Plan

Training for a half marathon requires commitment, but a sensible plan makes it achievable for most fitness levels. This 12-week approach balances progression with recovery, reducing injury risk while building the endurance you need.

Weeks 1–4: Building Your Base

Start with three runs per week: an easy run, a tempo run, and a long run. Easy runs should feel conversational. Tempo runs are harder—you can speak short sentences but not hold a full conversation. Long runs start at 5–6 miles and increase by roughly a mile each week. Include two cross-training sessions (cycling, swimming, or strength work) for injury prevention.

Weeks 5–8: Building Speed and Distance

Increase to four runs per week. Add a speed work session using intervals or fartlek training—varying your pace within a run. Your long run reaches 9–10 miles by week 8. These weeks build cardiovascular fitness and teach your body to run faster. Don't skip recovery runs; they're genuinely easier than they feel necessary.

Weeks 9–11: Peak Training

Your long run peaks at 10–12 miles. Maintain speed work but reduce overall volume slightly to allow recovery. Include one "race-pace" run where you practice the pace you'll aim for on race day. This familiarises your body and mind with the effort required.

Week 12: The Taper

Reduce mileage by 50–60%. Your body needs recovery time before the race. You might feel anxious during the taper—this is normal. Trust your training. A few short, easy runs keep your fitness ticking without fatigue.

Nutrition During Training

Fuel properly to support your training. Eat carbohydrates and protein within 30 minutes of finishing runs. On long run days, consume energy gels or sports drinks after 60 minutes of running. Hydration is equally critical—drink regularly throughout the week, not just during runs.

Managing Fatigue and Injury

Listen to your body. Minor aches are normal; sharp pain isn't. If something hurts, take an extra rest day. Stretching, foam rolling, and strength training prevent many common injuries. Sleep matters too—aim for seven to nine hours nightly.

Mental Preparation

The final weeks involve mental training. Visualise completing the race. Break the distance into manageable chunks—focus on reaching the halfway point, then take it from there. Race day will be challenging, but your training has prepared you.

Follow this plan consistently, stay patient with yourself, and you'll cross that finish line.
