So...
I’m on Week 4 Run 2 and have always used the treadmill at the gym near my work.
I don’t find the runs particularly easy at all and Week 4 Run 1 was pretty knackering, but, having read some of the conversations on here, should I be doing outdoor running for the app?
Is it ok to just use the treadmill and still claim success if/when I get to the 30 mins runs at the end!?
