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.

• Apple Watch App and Glance.
• 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.

• Includes animated stretching programs with voice cues.
• Integrates with the Health app and HealthKit.

• Daily tips for your training program, including information about pacing and nutrition.

• Complete program where you run 4 times per week.
• Total of 12 miles (19km) to 21 miles (33km) per week.

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.

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.

Ratings and Reviews

Long Run Crashes


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.

Great for my first half!


I trained for my first half marathon with this app and loved it! I liked that it was distance-based and not time-based, and I really enjoyed checking off the days on the map for each run I completed. The only issue I had was that I only received the audio queues sometimes, and you would never really know when they would work or not. My husband and I used the app at the same time and sometimes he would hear it during the run and I wouldn't, or the other way around. Didn't bother me much though since this app had everything I was looking for.

Enjoy the visual


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!!
