I’ve been a runner for 30 years and I’ve waited that long for this app. 26.2 just got jacked — you can do this!!

Excellent

Great for a first timer like me. Starting from a very low level of fitness, I used it to train for the 2016 LA Marathon (which I finished, not fast, but finished). Easy to use, straight forward and it works as promised. Currently restarting the program from the beginning to train for my next race. It's easy, just follow the day by day instructions and you will be ready to go. Couldn't ask for more.

Run Training

It’s a great app to do speed training. Went from C10K to this one but started on week 10. 1> for speed.

Disappointing it’s changed

It is very disappointing that Zen Labs have changed how the app works. I paid a one off fee for the app several years ago. I haven’t used for a long time due to injury and now I only get a week before having to pay a regular subscription! That doesn’t seem very fair. I will be looking for a new app.

RIP off

The app said a year subscription was $39.99, which is roughly £30, but the store tried to charge me £50 for a year which is a ridiculous price increase
