Just got back from week 4 run 2 and feel great! Last minute of 5 min run at the end took a bit of a push and I ended up a nice shade of beetroot but it was fine.
I feel much fitter than when I started - I know I wouldn't have been able to complete that run at the beginning; it's very encouraging to know I am improving. It such quick progress, only one more week 4 run and I am stepping up again!
Good luck to everyone starting out, it's a great program!
