Hi, C25k is a fantastic app, it doesn't take long - but you do need to prioritise it - especially in early weeks to form a habit.
I find setting a time / date with the gym or where I run outdoors helps.
Having my gym kit at the ready, and doing it .. no excuses.
I started running again on 28th Dec after promising my teen we'd do a race for life this year, she's 16.. runs faster than me but we head out together and meet up at the end for cool down. So I run alone.
it's wonderful for clearing your head, and the buzz after is amazing.
