I've used this app twice before and it was great - I was regularly running 10-12k (nonstop). Now, after pregnancy & baby, I'm keen to get back to where I was, but unfortunately you now have to pay for it. I'm not willing to do this as I'm aware there are plenty of other free apps (and even an AI that could work a programme out for me!) out there. I'm quite disappointed 😞

Suddenly have to pay?! I used this app 2 years ago for 10 mile training. Have started using it again for half marathon training only to discover that today, I have been charged for it. £18.99. So so disappointed. Even more so because I have also downloaded the half marathon app from the same company which also cost £18.99 (although i was aware of this cost when i downloaded). The app always worked well for me, was never any problems. So I'm sad that I will need to find an alternative.

I used this app as the natural progression from their 5k app. When I started the program I never imagined I could do 10k, but this works. 3 runs a week, follow the steps and I am now doing 10k, and for the record I am 43 at the time of writing and overweight. If these apps can get me to 10k and beyond they can do it for anyone!! The only real thing I wish the app had, was more regular feedback on distance/progress during the runs rather than just half way and 1 minute left but still amazing.
