The best marathon training app gives you a plan that fits your current fitness, your race date and the days you can run, then adapts when life gets in the way. Choose by the kind of guidance you want: coach-written plans, adaptive AI plans, run-walk methods or detailed training data. Ten apps follow in no particular order.
A marathon is a few hours on race day and months of training before it. The plan is what gets you there, and a good app takes the guesswork out of every week: how far, how fast, when to rest and when to push.
The ten apps below are listed alphabetically and in no particular order, from coached plans and adaptive apps to run-walk programmes and detailed training logs. Each description comes from the app's own App Store listing, re-checked this week. This is general information, so speak to your doctor before starting if you have a health condition. If you're travelling for a race, my smart travel and fitness tips have ideas for staying active away from home.

Build the base before the plan
Marathon plans assume you can already run regularly. If you can't yet, start smaller. The NHS says its free Couch to 5K programme guides you from the couch to running 5km in just 9 weeks.
Want AI doing the heavy lifting in your marketing?
I build the systems that handle the boring 80 percent, so you get your week back. Done properly, with the human kept in.
What that means for you: if 5km still feels hard, get there first. Building that base before a marathon plan makes the longer runs far less daunting and gives your body time to adapt.
Coached, adaptive or run-walk?
Coach-written plans give you a fixed schedule from an experienced coach, which suits people who like structure. Adaptive apps adjust your plan based on how your runs are going, so a missed week doesn't derail everything. Run-walk plans build in walking breaks, which many first-timers find gentler on the body. Training log apps suit data lovers and people working with their own coach.
Whichever you choose, the long run and the rest days matter more than the app's features. Look at how a plan handles missed sessions before you commit; life gets in the way of every training block, and a plan that shrugs off a lost week is far easier to stick with than one that makes you feel you've failed.
Getting through a training block
- Pick your race and count back to find your start date.
- Choose a plan that matches your current weekly running.
- Schedule runs in your calendar like appointments.
- Practise race-day food and drink on your long runs.
- Take rest days seriously; they're when you get fitter.
- Taper in the final weeks as your plan suggests.
Training mistakes to avoid
- Running every run hard. Most training should feel easy.
- Skipping rest days. Recovery is when your body adapts.
- New shoes on race day. Race in shoes you've trained in.
- Ignoring niggles. Rest early before small aches become injuries.
Fuelling and the long run
Long runs are where you practise everything you'll do on race day: pacing, drinks, gels or snacks, and the clothes you'll wear. Think of them as dress rehearsals. If something upsets your stomach or rubs on a long run, you've found out at the right time, with weeks left to change it.

My plain advice on marathon training apps
Pick a plan that starts where you are today, not where you'd like to be. Most training problems come from doing too much too soon, so an app that builds gently and adapts when you're tired is worth more than one with the fanciest charts.
Then trust the plan and protect your rest days. Consistency over months beats heroic weeks followed by injury. If you're new to running, the NHS Couch to 5K is a brilliant first step before you even open a marathon app. My research and free tools page has more practical guides.
