■ The Official Half Marathon Trainer App ■ Featured on The New York Times, Los Angeles Times, The Washington Post, The Guardian, The Huffington Post, Men's Fitness, Forbes, Mashable, Glamour Magazine, Popsugar Fitness, CBS News, NBC News, Macworld, Cosmopolitan, Lifehacker and many more! From the same makers of the #1 C25K® Trainer app, Half Marathon Trainer follows the same successful recipe to create an easy 13.1 (21k) program. Ideal for first-time half marathoners and those who are new to running. The program uses a blend of running and power walking to run-walk the entire half marathon. See thousands of real success stories and race photos of your fellow runners using these running program at Facebook.com/c25kfree ≈ IMPORTANT ≈ This app will train you to complete a full 13.1 (26K) distance using a RUN/WALK strategy. This proven 14 week plan is designed for beginner/novice runners. The run/walk breaks help make the half marathon less grueling, as well as reduces the overall impact and risk of injury. But don't think that just because walking is involved that your time will be slower, or that you're accomplishing less. Many veteran runners have posted personal best times after switching to this run walk method! By using a ratio of running and walking, you can manage your fatigue which gives you the muscle resource and mental confidence to handle the later parts of the race. Slowly build strength and stamina, and the blend of walking and running together reduces the overall impact and risk of injury. By the end of the program, you will be READY for your 13.1 (21k) race! Listen to your favorite music while you train and follow the 13.1 program’s convenient audio alerts. Along with voice/audio alerts and music controls on your headset, just press “start”, put your device in your pocket, and you are ready to go. Alerts will tell you when to warm-up, walk, run, cooldown, and when minute is left to give it your all. ≈ Features ≈ ◉ BRAND NEW MUSIC curated from top DJ's, built right into the app (subscription)!

  • Minor additions

    By Mick62114
    Wonderful app. The only additions I’d like to see are a GPS map of the course you ran after you finish and louder alarms in comparison to the music that is playing or maybe a longer pause in the music during the transition periods.
  • Works great

    By petit princesse
    The only thing this app doesn’t provide is your minute/mile pace, which I would like to track to mark my improvement. All you get is your distance and calories burned and I’d prefer more detailed data about my run. The audio cues work well and the app is easy to use.
  • Opening chime

    By sienfbfkslwpepjfbf f
    Why would you change the chime when I open the app. I’ve been training with this for years and I hate the new chime.
  • Not for you if you’ve run half marathons

    By Redheadelis
    I had the impression I’d be able to customize the training schedule. You cannot. And you have to have your phone with you while running so it doesn’t truly work with your Apple Watch as a stand-alone app. I’d like a refund.
  • Not a fan of the update

    By chawks64
    Worked great before, but now it paused itself at least three times in (what should have been) a 43 minute run. And yes, the screen was locked. If this can be fixed, I’d be a happy customer again. If not, I’ll have to use another app.
  • This app works well

    By Krgwsly
    I like how well this app works. Coaching voices are clear, integrates with my music app. Good motivation app
  • Fix the sound

    By Jsid26
    Great app but it softens my music and its quite annoying. Would be a 5 star but the constant volume juggle is hindering it.
  • Good but glitchy

    By Buggirl76357
    I love this app in theory but as I’ve gotten farther into it (around week 7 I think) it’s started glitching on time. I’ll look at the time then do a cycle or two and look at the time and it will be the same or it will say workout completed but when I open the app time is still left. I’ve updated and don’t want to lose my progress. I’ve also found the distance isn’t very accurate but I just run map my run in the background and it isn’t an issue. Overall I would recommend it for at least getting into it!
  • Great app, but...

    By KickingAS
    I really do love this app, but for some reason it is not syncing with my Apple Watch. Sometimes it buzzes when to walk/run, and then sometimes it doesn’t. Probably would give it a 5 star if it would work right.
  • Ex-Athlete Getting back in-shape

    By Brookglenn44
    This app is fantastic. It’s exactly what I’ve been looking for to get back in good shape after my athletic career. This program eases you back into working out regularly at a safe pace.
