Most serious marathon runners do not rely on a single app. They build a small toolkit - one for training, one for tracking, one for the watch on their wrist, and one to make sure they actually get into the race in the first place. Here is the honest breakdown of the apps runners reach for in 2026, what each one is genuinely good at, and where the gaps are.
None of these tools compete with each other, despite what the app store might suggest. They solve different problems. The trick is knowing which tool to use for what - and not paying for overlap you do not need.
Strava - The Tracking and Community Layer
Strava is the default tracking and social platform for runners. Its strength is not the training plans (the free tier has none) or the route planning (decent but not the best in class) - it is the community and the data history. Strava is where you log every run for years, where your friends see what you did, and where segments turn a Tuesday tempo into a competition.
Best for: long-term activity history, segments, kudos, social motivation, and syncing data from almost any watch or app. Not for: structured training plans, race calendar tracking, or lottery alerts. Strava knows what you ran yesterday - it has no idea when the London Marathon ballot opens.
Runna - The Adaptive Training Plan
Runna has become the go-to paid training app for runners with a specific race goal. You enter your target race, your current fitness, and how many days a week you want to run, and Runna builds a personalised plan that adapts as you go. Its sweet spot is the runner who wants the structure of a coached plan without paying for an actual coach.
Best for: personalised marathon and half-marathon plans, pace targets, and adaptation to missed sessions. Not for: social tracking (it integrates with Strava for that) or - critically - getting you a race bib in the first place. Runna assumes you already have one.
Garmin Connect - The Watch Ecosystem
If you own a Garmin watch, Garmin Connect is non-negotiable. It is where your runs land, where you see metrics like training load, recovery, VO2 max estimate, and Garmin's own coaching workouts. The hardware-software integration is what makes it valuable - features like real-time pacing, structured workouts pushed to the wrist, and detailed post-run analysis just work in a way third-party apps cannot quite match.
Best for: Garmin watch owners who want deep physiological metrics and on-wrist workout guidance. Not for: non-Garmin users (it is heavily tied to the hardware) or anyone looking for race registration tracking.
Nike Run Club - The Free Companion
Nike Run Club is the best free app on this list. It offers guided audio runs led by coaches and athletes, simple training plans, and community challenges. It is the app to recommend to a friend who just bought their first pair of running shoes. For experienced runners, the guided runs are surprisingly good for variety on easy days.
Best for: beginners, free guided runs, and easy days when you want a coach in your ear. Not for: highly personalised marathon plans or anything to do with race entries.
BibsAlert - The Missing Piece
Here is the gap none of the apps above fill: they all assume you already have a race bib. They train you, track you, and analyse you - but if you have ever tried to enter a race like the London Marathon, NYC Marathon, or Tokyo Marathon, you know the actual challenge: registration windows open without warning, lotteries close fast, and first-come-first-served races can sell out in hours.
BibsAlert is the small, focused tool that closes that gap. It monitors the official websites of major marathons worldwide and sends you an email the moment registration or a ballot opens. That is it. It does not track your runs, build a plan, or analyse your VO2 max - the apps above already do that better than we ever could. It just makes sure you do not miss the start line.
Best for: runners targeting competitive races with lotteries or fast sell-outs. Not for: training, tracking, or anything you would use Strava, Runna, Garmin or Nike Run Club for.
Already use Strava and Runna? Add BibsAlert to your stack so the next ballot opening does not slip past you while you are out training.
Putting It Together: A Real Marathon Runner Stack
There is no single right combination, but here is a stack that works well for a runner targeting one or two big marathons a year:
- Garmin watch + Garmin Connect - the hardware does the measuring on the run.
- Runna - builds the plan, sends workouts to the watch, adapts when life gets in the way.
- Strava - the long-term archive and the social layer. Auto-syncs from Garmin.
- Nike Run Club - optional, for guided easy runs when you want some variety.
- BibsAlert - the alert layer that gets you into the race in the first place.
Total cost: a Runna subscription, ten dollars a year for BibsAlert, and free for everything else. None of these tools fight each other, and removing any one of them leaves a real gap.
Frequently Asked Questions
What is the best app for marathon training?
There is no single best app - most marathon runners use a combination. Runna is excellent for adaptive training plans, Strava is the standard for tracking and community, Garmin Connect is best if you own a Garmin watch, and Nike Run Club offers free guided runs. BibsAlert covers the one thing none of them do: telling you when race registrations and lotteries open.
Does Strava send marathon lottery alerts?
No. Strava is a training and activity tracking platform - it does not monitor race registration windows or lottery openings. Runners who want lottery alerts typically use a dedicated tool like BibsAlert alongside Strava.
Is Runna better than Nike Run Club?
They serve different purposes. Runna builds personalised, adaptive training plans for specific race goals and is paid. Nike Run Club is free and focuses on guided audio runs and community challenges. Many runners use Runna for structure and Nike Run Club for variety.
How do I make sure I do not miss a marathon registration?
The training apps above will not help with this - they track your runs, not race calendars. BibsAlert monitors official race websites and emails you the moment registration or a lottery opens, so you can apply before the deadline closes or spots sell out. Browse the tracked races or check the marathon calendar to plan your season.
