How to Train for a Marathon as a Busy Woman: A Time-Saving Plan

How to Train for a Marathon as a Busy Woman: A Time-Saving Plan

Marathon training is demanding, but if you’re balancing work, family, and life, you don’t have to run six days a week to be successful. The key? Training smarter, not harder.

Whether you're a busy mum, corporate professional, or juggling multiple responsibilities, this guide will help you prepare for your marathon efficiently - without burnout.


The 3 Pillars of Efficient Marathon Training

Traditional marathon plans often require high mileage and long training weeks, but that’s not the only way to get race-ready.

At Pretty Strong Coaching, we focus on these three essential pillars for busy women:

Quality Over Quantity – Focus on key sessions, not endless miles

  • You don’t need to run every day—3-4 targeted sessions per week can be just as effective as 5-6, especially when combined with strength work.

  • Prioritise long runs, speed sessions, and recovery runs rather than logging junk miles.

Hybrid Strength + Endurance – Build resilience & avoid injury

  • Incorporating strength training for runners improves speed, endurance, and injury prevention—critical for women who have less time to recover.

  • Stronger muscles = better running economy, fewer injuries, and faster race times.

Adaptability – A plan that fits your life, not the other way around

  • Life happens—kids get sick, work deadlines pile up, and motivation fluctuates.

  • A flexible marathon plan helps you adjust sessions without guilt and stay consistent.


The Best Workouts to Maximise Efficiency

The 80/20 Rule is a game-changer for busy women:

80% of training at an easy, low-intensity pace (building endurance)
20% focused on speed & strength (boosting performance)

Instead of daily runs, focus on these three key runs per week:

Long Run (Endurance Focus)

  • Your most important session—prepares your body for race day.

  • Start where you are and increase weekly mileage gradually.

  • Aim for one long run per week, increasing 1-2km per week.

Speed or Tempo Session (Boosts Pace & Mental Toughness)

  • Interval Workouts (e.g. 6 x 3-minute efforts at 10k pace)

  • Tempo Runs (sustained effort at slightly uncomfortable pace)

Why? Shorter, high-intensity sessions improve endurance without extra mileage.

Easy Recovery Run or Cross-Training

  • Optional but beneficial for active recovery.

  • If time is tight, swap for cycling, swimming, or strength training.

💡 Bonus Tip: If you're limited to three runs per week, adding one strength session makes your training more effective.


How to Adapt Training for Low-Energy Days

You won’t feel fresh every day—that’s normal. The key is adjusting, not skipping.

  • Feeling exhausted? Swap a hard session for an easy 30-minute run or walk.

  • Short on time? Cut your run in half but keep the intensity (e.g. a 20-minute interval session instead of 40 minutes).

  • Stressed or overwhelmed? Reduce training volume but stay consistent with movement.

💡 Listen to your body: Rest when needed but avoid back-to-back missed sessions.


Why Strength Training is a Game-Changer for Women

Strength training isn’t optional - it’s essential.

Women naturally have less muscle mass than men, making strength work even more important to reduce injury risk and improve endurance.

Core Strength → Reduces fatigue & improves posture.
Lower Body Strength → Increases power & running economy.
Injury Prevention → Stronger muscles = fewer running-related injuries.

Best Strength Exercises for Runners:

  • Single-Leg Deadlifts (hamstrings & balance)

  • Squats & Lunges (quads, glutes, & core stability)

  • Planks & Glute Bridges (core & hip strength)

💡 2 short strength sessions per week = better running performance without more mileage.


Real Talk: You Can Train for a Marathon on 3-4 Runs Per Week

Many Pretty Strong Coaching athletes successfully train for marathons on 3-4 focused runs per week + strategic strength work.

What really matters? Consistency, progression, and smart fuelling.
What doesn’t matter? Running every day just for the sake of it.

💡 Reminder: Busy women don’t need “perfect” plans—just effective ones.


What to Eat for Marathon Training (Without Overcomplicating It)

Fuelling properly is just as important as training.

Pre-Run: Carbs + small protein (banana + peanut butter, toast + jam, or porridge + berries)
During Long Runs: 30-60g of carbs per hour (sports gels, dates, energy chews)
Post-Run Recovery: Protein + carbs (Greek yoghurt + granola, eggs on toast, smoothie with oats)

Hydration Matters: Aim for 2-3 litres of water daily + electrolytes for longer sessions.
Don’t Under-Fuel: Restricting calories leads to fatigue, burnout, and increased injury risk.

Marathon Training Myths (That You Can Ignore)

🚫 “You have to run every day.”
✅ Nope - 3-4 focused runs per week + strength = success.

🚫 “Tapering makes you lose fitness.”
✅ Wrong - tapering (reducing mileage before race day) is essential for peak performance.

🚫 “Marathon training = weight loss.”
✅ Not necessarily - fuelling properly is key for energy, performance & avoiding injury.
