10K Trainer is the easiest program to get beginners from couch potatoes to 10K distance runners in just 14 weeks. By the same experts who created the #1 C25K (Couch to 5K) training app!

Don’t worry, if you are already a 5K graduate, you can skip ahead in this app and pick up where C25K app leaves off!

This proven 14 week plan will allow users to slowly build strength and stamina by alternating between walking and running. The blend of walking and running together reduces the overall impact and risk of injury, makes training more fun, keeps your body guessing, and prepares you to go the distance. By the end of the program, you will be fitter, stronger and healthier than you have ever been and will be able to run a full 10k!

Listen to your favorite music while you train and follow the 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. NEW smart alerts will tell you not only when to walk or run, but will also tell you for how long!

≈ Features ≈
◉ FULL featured program! Not a limited/lite version
◉ Proven 14 week program to get you running 10K
◉ Easiest 10k program at only 3 times/week
◉ Listen to your own favorite music and playlist while you train
◉ Easy and intuitive interface. Nothing to learn!
◉ Convenient audio coach and alerts
◉ Compatible with Nike+GPS

Not bad at all
Leyna-Lu on 12/4/2017
This app tells you what to do on a run without being strict, it simply gives the notification to “run” or “walk.”
i like it
Azooz blablabla on 11/30/2017
this is an amazing app !!
A good start
Nice Tri on 11/27/2017
As a health and fitness professional, I will encourage my patients to use whatever tools work for them. This one is popular and I’m giving it a go myself. My first impression is that it is good for accountability. A long second to an actual running partner, this app still may help us to get out the door. The progression is simple, yet walking alone should be the first step from the couch for 1-6 weeks, depending on one’s fitness. What is lacking for me is that other side of running- the sprints, tempo runs, fartleks, hill work, etc. Some may argue that C210K is powerful in its simplicity. I just see it as lacking. If running a 10K truly is your end goal, fine. But if you want to improve your fitness and longevity, I recommend adding core exercises, carries, toe and heal walks, and much more that could easily be integrated into the app.
QuestJones on 11/27/2017
Helped me prep for runs.
First run on 10K app
Blixter77 on 11/26/2017
Used C25K to work up to a 5K over the last couple months. Decided it’s time to kick it up a notch. Works identically (which is great) and it skipped several weeks that were covered in the C25K app.
Love it!!
Flnfrgge on 11/24/2017
I have done a C25K app similar to this one years ago. I stopped running after I finished it because I couldn’t didn’t know how to work into a 10K. (and lost motivation) I decided to try this as inspiration to work straight to a 10K. Loving the fact that when I complete it, I can click a link that will take me to their half marathon training app (if I decide to go there).
Great app...could use a couple more features
S43D06 on 11/24/2017
I've been using the app for a couple weeks and it's doing exactly what it's supposed to do...get me off the couch and back in the pavement! It has a lot of bells and whistles but one thing I'd like to see is a way to control the volume of the notification beep and the voice. I often cannot hear the voice telling me to walk or run.
Wmeoejn on 11/15/2017
Great workouts
Lemonaiding on 11/9/2017
More than halfway through and still training. Great App.
10K app
canela 1953 on 11/7/2017
I am 64 years old. Little over a month ago I could not run or jog for one whole minute. Today I was able to run for 20 minutes !!! Great app!!! Great program !!! Thank you!!!
Great running app
Keez12 on 11/7/2017
I found the verbal cues very helpful, especially the halfway done cue.
Fantastic App!
Azlaxion on 11/3/2017
I have been using this app to prepare for runs for a couple years now, and my runs keep improving. Easy to use, and no more shin splints since I started slowly.
So good...so far
BeFunkyFan on 11/2/2017
App seems to be working fine so far. It's only been two days. I'll come back to update in awhile.
Thank you! Easy, helpful, encouraging app. Keep up the great work!
Jamie Camie on 10/21/2017
Great app. Very easy to use, and almost identical to the C25K app. After I completed the C25K running app, it gave me the option to download this 10K trainer, the next app in the series. Once I did, instead of starting me at the beginning, the program started me at week 6, because it recognized I was already capable of the 5K. That was a great feature...it's a huge perk how all these training apps are from the same company, so they're all connected and easy to use. It still gives you the "one minutes remaining" audible announcement, which is handy. I like all the voice notifications (when to begin running, stop running, and when I'm half-way) because then I can just go and listen to music, without having to look at my phone. Thanks for the easy-to-use, beginning runner-friendly app! Combined with healthy eating (and minimal extra sugar and bread), I am in the best shape I've been in, in 5 years.
Good accountability, but a 1 minute run to start seems intense!
Odessa730 on 10/18/2017
I like this app for the gradual increase, but I think as a beginner, the 1 minute running during week 1 should have started at 30 seconds and gone up from there. Also, no verbal cues when my phone is locked.
Great app
Ott8788 on 10/17/2017
Getting me ready to be dead sexy!!
Helping me to my second 10K
Great for bus commuters on 10/17/2017
I didn’t know Couch to 10K existed, but I used the C25K app for my first 10K and found it to be really helpful. I was thrilled to have found C210K, and look forward to running my second 10K in a few days. Thanks for getting me there, app developers!
New mom jogger on 10/15/2017
Free portion is decent - not a lot of talk just quick instructions... don't know about the purchased side- I'm cheap... took off a star just because I think using the app interferes with playing my own music- I have to hit play for every single song- not easy whilst jogging and I don't usually have to do that if I'm not using this app.... otherwise decent app! We'll see if I can get to a 10K in this few weeks.......
Notifications problem iPhone
EastCoastJetski on 10/11/2017
Please update app so that it shows in my notifications settings for iPhone IOS 11. Also, please workout history view that includes distance, pace, and calories.
Best Work out app
Diva2720 on 10/7/2017
I've always wanted to be a runner. This app and the C25k app has been making me reach my goal. I am very satisfied with the pace of the app. I would recommend it for the beginner runner or anyone interested in training for a marathon
Good for a free app
Lambertval10634 on 10/7/2017
I'm not new to running but I needed a reboot so I downloaded this app...today was the first time I've used it and I was very pleased. It doesn't tell u the distance/pace without paying so from now on I'll wear my garmin as well but I did like the freedom of being told what to do and when to do it...not as good as a coach but hey coaches aren't usually free either lol
Great app!
JOBAFATT on 10/5/2017
Great app!
The finish line for running moved closer
Jjspencer on 10/4/2017
I once listened to a ted talk that said the difference between physically fit people and non physically fit people is that the finish line seems too far away distance wise for the unfit people which causes the brain and body to not like running... well with c25k and couch to 10K it feels like the finish line is a bit closer for us non physically fit people. I mean I have learned to breathe while running and the breaks and cool down periods in the app are awesome for beginners like myself. I'm happy a friend recommended I download this.
Great way to get back in shape.
googley4444444 on 10/2/2017
Timing and notifications from the app really help it's overall performance.
Needs Work
kisshusgirl on 9/28/2017
If i put it on the lock screen or go to a different app, it does not warn me when to start walking or running. Instead, it sends it as an alert. Very unhelpful!!
Love it!
T0oyett on 9/26/2017
Love this app. Easy to use!
Made it so easy
rdyyyyyyyy on 9/26/2017
After trying to start running dozens of times throughout my life, at 46, I was finally successful with the c25k app. Now a I've transitioned to the 10K app & I'm still improving. I love being able to listen to music or podcasts and get background guidance that makes improving my endurance effortless and helps my workout fly by.
Keeps me motivated!!
JenB007 on 9/25/2017
Love it!
Best free app I have found
XmasDog on 9/19/2017
Unlike other apps, this is still free after the second week. There are a bit of pop ups but it's free soooo
Triathlon training
kabatchie21 on 9/18/2017
Great program, well designed app. Just be sure to completely close out when done so it doesn't run in the background and drain your battery.
Great app for beginner runners
moreliasam on 9/18/2017
Good sequence of running to build up endurance. I enjoy the inspirational quotes at the beginning. No complaints so far.
I really enjoy that app
Nie ma wolnych nicknameow on 9/18/2017
It's a great start for someone that's been sitting on the couch for too long!
Kills battery
peophin on 9/15/2017
I normally really enjoy this app, but for the last week or so, my phone battery has been draining at an alarming rate, even when I'm not using it. Nearly found myself buying a new phone! No need - it was this app constantly running in the background (for what?). I hadn't even opened it in months and it started refreshing constantly in the background. 70% of my battery life went to this app when I finally looked at battery statistics... that needs to be addressed!
Keeps me going!
aelxsi on 9/14/2017
This app doesn't let me slack as long as I keep going.
Great for free
Charlie126375827517885 on 9/9/2017
Has little issues like integrating with spotify but otherwise works like a charm
A great way to get moving.
Carhuey on 9/7/2017
This is a great App, it helps keep you motivated and keeps increasing a little at a time. Makes running 10K a breeze
Well Worth It
tempi2007 on 9/6/2017
I successfully completed C25K and easily moved on to C210K. I'm currently in the first work. My only negative would be that it's almost too easy, but I'm confident I the workouts will become more strenuous next week.
Great App!!!
Drgsmitty86 on 9/5/2017
Must have for serious and new runners
Not bad at all
skty80 on 9/5/2017
It's a pretty good app better than I expected just don't forget to turn up your volume so you can hear the prompts of winter start running and continue walking I like the program better on the road or on a trail rather than on the track because the track I look for visual points instead of just enjoying the run
Somewhat unrealistic for beginner
Cheryl31252 on 9/4/2017
What happens in week 5? Day 5-2 run 8 minutes. Day 5-3 run 20 minutes. 20??!!?? Are you serious? What happened to gradually increasing duration? Overall I like the program, but jeez!
Shanskg on 9/4/2017
Ap keeps you motivated to complete your goals. Even tells you when you need to get back at it when you haven't connected for awhile
C25K & C210K
salias71 on 9/3/2017
I finished my first 5K almost a year ago and fully credit the C25K app for it. I NEVER thought I could run one. Totally changed it for me. I just started the 10K app and we're off!
Great App So Far
DDAY1968 on 9/2/2017
Great app so far. On week four, and I'm seeing progress:). My goal is getting back to my Marine Corps Days. September 2, 2017. Doing much better with my runs, and the 10K app is keeping me on pace. Semper Fi!!!!!
Great app
Lynn in Atlanta on 9/1/2017
Works well, motivates me to push myself. I recommend it to anyone who wants to learn to run. Do it!
keeping on track
S:^) on 8/31/2017
Like a coach that never gets angry 😎 & easy to use at the same run with other apps
Love this
Steth and Scones on 8/30/2017
I love this app. I have it on my iPad and iPhone. Sometimes I run on the treadmill while watching Netflix on my iPad. The app seamlessly works while running video. I also use the app on my iPhone at the gym while playing Spotify and it is seamless there as well. I've been using the app for a few months now and can say that the interval training program really works. I went from someone who never runs and has no endurance to easily running a 5k.
Pretty good
Vskroch on 8/30/2017
This app works well for the most part and helps keep you on track with your training. However, the voice cues didn't work if my phone went in screen saver mode and, although the pro version keeps track of your distance, there are no voice cues to tell you your pace or distance during your run. It makes it hard to tell if you are keeping pace.
Interesting app
Notsureaboutthisproduct on 8/27/2017
Looks like an interesting app. I have just started and it worked fine for day 1. Wait to see how it goes. The premise is that follow the app instructions blindly.
Haven't opened the app today but it's responsible for 33% battery usage
Civicmon on 8/26/2017
Fix this. That's absurd and I haven't even used the app today!!
