Optional slower pace of progression please

Running isn't easy. Starting out running is even harder. Trying to start running when you have asthma feels impossible. Running will help build lung endurance, but the asthmatic runner has to understand that while their perseverance will get them to the same abilities of running as someone without asthma, they will progress slower. That being said, how about a slower paced option on this app? It took me three weeks just to get past week one of this program comfortably. Perhaps you can have a setting option (you don't have to say it's for asthmatics, who should seek medical advice - just for anyone who would want or need the feature) where a user could select a slower pace of progression through the program. You could have a slower course with easier transitions. That would be nice to try to help someone who needs to exercise but not get discouraged or frustrated because they can't keep up. You'd be the only ones to have such an option - making you more valuable.

Helping me become a runner!!

As an adult, I had stopped running because it hurt my knees too much (I'm more of a swimmer). I tried this app to prepare for the 5K for Wanderlust. I love how it starts out easy and it builds up as you build up your stamina and endurance. It still hurt a lot the first time, but it was short enough that two days later, I was willing to do my next round. I found that I was able to keep up AND, I was blessed with tips from runners on Instagram on how to land, to take smaller steps, and to pace myself. I'm only on week 4 but I'm so happy that I can run 5 minutes without stopping!!! It made me motivated and I bought new jogging clothes and audio books. I'm so excited now about running that I've run three days consecutively without a break! Who would have thought this would become a "habit"! Lol. Thank you so much for this app!!!

Great app but allow more than 8 weeks for a true couch to 5k

Just ran my first 5k this weekend after training using this app for the past 10 weeks. It's a great app to build up to running the distance but if you are older and not as fit, as I am, you will likely need to extend your training to complete the program. Towards the end of the training program, the time to complete the distance is unrealistic for someone who's never run before. To compensate for this, I extended the run times to meet the distance at my slower pace (13 min mile), then repeated weeks 7/8 during weeks 9/10 until I got to 3.1 miles at my pace. I would still recommend this app for anyone wanting to complete a 5k without walking as it does work to build your endurance in a structured way.
