The marathon is the pinnacle for many runners – 42.2 km (26.2 miles) of physical and mental endurance. It’s a distance that requires patience, consistency, and commitment, but crossing that finish line is one of the most rewarding experiences in sport.
Whether your goal is to complete your first marathon or chase a Boston qualifier, the right training plan is essential.
At URUNN, we don’t just hand you a schedule – we coach at every iteration, combining expertise, structure, and support to make marathon training achievable and fulfilling.
At URUNN, no two marathon training plans are the same. Every plan is tailored to your fitness, history, lifestyle, and goals.
We want to understand your journey – no matter if you’re stepping up from a half marathon or chasing a sub-4-hour finish.
From there, the URUNN app builds a plan that adapts as you go. If you miss a run, it adjusts. If you progress faster than expected, it pushes you further. If life gets in the way, it recalibrates so you never feel like you’re falling behind.
This personalised approach means training fits your life, not the other way around – giving you the best chance to run strong and finish proud.
URUNN makes marathon training personal, flexible, and motivating — so you show up on race day ready.
With URUNN, every step of your marathon journey feels structured, supported, and achievable.
The half marathon requires stamina, pace control, and mental toughness. Your plan will include a mix of runs designed to build both endurance and speed:
Easier sessions
Hard sessions
Longer efforts
Running is only part of the equation. To succeed over 42.2 km, you need a holistic approach.
Strength and mobility are essential to your marathon training. These sessions target the core, glutes, and legs, improving running economy and preventing injuries like IT band syndrome or Achilles issues.
Marathon success relies heavily on fuelling. In training, you must rigorously practise your race-day strategy.
This means testing everything from your pre-run meal (a carb-based, easily digestible snack taken 2-3 hours before the effort) to your mid-run fuel (practicing the timing and type of gels or chews you plan to use). You need to take in 60-90 grams of carbohydrates per hour after the first 90 minutes of your long runs.
Day-to-day, focus on a balanced diet rich in complex carbs (like oats, rice, and potatoes) to keep your energy tanks full, lean proteins to drive muscle repair, and healthy fats for sustained energy and overall health.
Finally, treat recovery fuelling as mandatory: consume a carb-to-protein mix within 30–60 minutes post-run to reload muscle glycogen and maximize adaptation.
Adaptation is where the magic happens. URUNN schedules recovery and complete rest days into your plan. Skipping them is one of the quickest ways to burn out or get injured; respecting them ensures steady progress.
The marathon is a race of patience. Even small pacing errors early on can cost you dearly in the final 10km. The best strategy is to run as evenly as possible at your goal pace, resisting the temptation to go out too fast.
Here’s a guide to common marathon finish times and average pace per kilometre:

"During Marathon training, avoid comparing your progress to others. With social media, it’s easy to feel like you should be running further or faster - but every runner’s journey is unique. Stick to your plan, trust the process, and remember: consistency beats comparison every time. "
Your race is the celebration of all your training. A smart race-week routine will help you perform at your best.
Marathon race day preparation
The marathon is as much mental as physical. A smart race-week routine ensures all your hard work pays off.
The final week
Taper properly – cut back mileage, but keep a little intensity with short race-pace efforts. Prioritise rest and nutrition.
The race morning
Eat a carb-rich breakfast 2–3 hours before (porridge, toast, banana). Hydrate steadily, and bring along your planned race fuelling.
Kit and arm-up
Wear shoes and the kit you’ve tested in training. Arrive early, jog lightly for 10 minutes, do dynamic stretches, and add strides at goal pace.
Mindset
Visualise your pacing and fuelling strategy. Remind yourself that the marathon is a long game – patience early, strength late.

Most runners need 16–20 weeks to prepare for a marathon, depending on their running background and goals. URUNN builds a personalised plan that adapts to your starting point, experience, and schedule.
Yes. URUNN gradually increases your long runs and weekly mileage so progressing from a half marathon to a full marathon feels manageable and safe.
Your URUNN plan adapts in real time. If you miss runs, get injured, or need to take a break the app recalibrates your training so you can keep moving forward.
Many runners do. A half marathon can be a great way to practice pacing and race-day preparation. URUNN lets you add half marathons or other events into your plan as B- or C-Races.
Fuelling becomes much more important for longer distances. During marathon training, you’ll practice using gels, drinks, or other carbohydrate sources on your long runs so you know what works best for you on race day.
URUNN provides real-time audio cues to guide your effort. The key is to start conservatively, settle into a steady rhythm through the middle of the race, and aim to finish strong.
URUNN guides you through a personalised recovery phase, then helps you choose your next goal — whether that’s another marathon, or chasing a faster PB.
