RunQuest 21k is a 13-week training program designed for 5k runners who want to run a half marathon. The workouts are distance-based, using GPS, and you get voice cues telling you your pace and progress every mile or km. This is a program for runners comfortable running 5km (3.1 miles) at least 3 times per week or runners who have recently completed our Run 5k or Run 10k app. FEATURES • Includes Apple Watch app. Get your workout info without having to take your phone out of your pocket! • Maps your run. • Speaks pace and distance. • Works in the background when you've switched to another app or if you've locked the screen. • Calculates calories burned. • Supports Bluetooth heart rate monitors. • Includes animated stretching programs with voice cues. • Integrates with the Health app and HealthKit. WORKOUT PROGRAM • Daily tips for your training program, including information about pacing and nutrition. • Choose your start and end dates. • Complete program where you run 4 times per week. • Total of 12 miles (19km) to 21 miles (33km) per week. • Works in miles or km. • Tapers in the middle and end of the program. • Automatically checks off each completed run. • Checks off your run on the calendar. • Option to manually enter treadmill, indoor, or other non-GPS runs. HEALTHKIT This app can be integrated with the Health app and be used with HealthKit. Your weight set in the Health app can be used to calculate Calories burned during a workout, and your date of birth and gender can be used to calculate your target and maximum heart rates. The total Active Calories burned can be saved to HealthKit after each workout. Sharing this information with HealthKit is optional. GPS and LOCATION This app requires an iPhone or iPad with GPS support. During a workout, location data is used to calculate distance and pace, and to record a track of your position on the map. For best results, use this app outside where you can see open sky. Note that continued use of GPS running in the background can dramatically decrease battery life.

During an 18k, I had to close the app and re-open it several times to get it going again. As my half marathon draws closer, I’ve given up using this and have switched to Map My Run. I still use this app as a guide for when and how often I should run, but I just can’t trust it to work properly which is a real shame. I’m not sure if other users have been affected by glitches? I agree with another reviewer that the option to switch the days you do certain runs would be beneficial - expecting someone to run 18 or 19k after a day’s work isn’t realistic! If these glitches could be fixed; this app would be ideal. ### 1/5 — Don’t waste your money *2018-07-26* I found several free apps that do as much or more. Integration with Apple Watch is poor. Will never buy a training app again that doesn’t give me a free preview. ### 3/5 — Simple and Straightforward.. BUT *2017-05-02, version 4.5.4* Really simple and straightforward app.. BUT. 1/ it's really flakey with BT hr monitors .. rarely does it work properly. 2/ it really doesn't store the data in the health app properly 3/ it shows up in the activity app, which Is good, but it doesn't calculate average HR.. so makes me less sure on the calorie calculation. 4/ for whatever reason the app has to be active, the screen on and the silent slider off to get the voice cues.. other than that😀 ### 2/5 — Long Run Crashes *2015-03-16* I started using this app 11weeks ago after graduating from the sister-app Couch to 5k app. In general, it is a fine design and the plan has worked well for me. However, I give it such a low rating because it crashes and loses my data during all of my long runs, usually somewhere between mile 5 and 7. I haven't noticed this issue during 3-4mile runs. This wouldn't be so much of an issue except that I run outside over sidewalks and trails, so I cannot keep track of my distance without the GPS. I get frustrated when I expect to hear the mile signal, check my phone, and discover that the app crashed on me and now I have to figure out through other apps how far I have run. The only reason I keep using this app is because the training program itself has worked well for me. Unless these issues are fixed, I will be switching to another training app for my next race. ### 1/5 — Was very good, now not so much:( *2015-01-31* Was a great app but recently started crashing and losing my runs and all my stats. Contacted support but they were no help at all. Only have 3 weeks left in my program otherwise I would find something else. Very frustrating. :( ### 5/5 — Ran a Half Marathon! *2014-04-25* I never thought I'd be able to run 13.1miles but this programme builds up your distance and stamina without overtraining you. Wish they would make a marathon version too! (Highly recommend the 5k and 10k versions for those not ready to conquer a 21k. I've done both of those too in previous years.) ### 5/5 — Refresh2 *2014-03-29* I the used their 10k and this was a natural progression. This app got me to my first half marathon without pain. I did well and felt great. Hope the developers come out with a full marathon app soon. That's my next goal. Can't wait ! Great suite of apps. ### 5/5 — Enjoy the visual *2013-10-31* I really enjoy this app. I used it to train for my first half marathon and thought the program was really manageable. I enjoy the calendar aspect and I also like the run tracking. It's very accurate and motivating. Also like that it breaks each mile down by pace and elevation. At the end of your run you can see your run. Great app all around. Plan on using it for my next half!! ### 2/5 — Waste of Money *2013-10-16* I have used the 10k app and 5k app from these guys and really enjoyed it.....this app however, not so much. It seems to rely solely on GPS, so those times you need to use the treadmill it's useless. Pretty bummed about this purchase. ## Frequently asked questions about RunQuest 21k ### What is RunQuest 21k?
