Well that's quite a step up from Week 3 runs!! I use the 'Get Running' app on my phone so am not sure it was exactly the same as Laura's ....but ran for 2 x 3 mins & 2 x 5 mins!!! It was hard going but worth it!! Really helps that I'm running with a couple of friends....works as such a motivator to keep going!!!
How have other people found moving upto week 4???
