Hi everyone I started running a couple of months ago. I followed the runners 6 week 5 k program, which I completed and was able to run 30 mins in one go (all treadmill training due to freezing weather and having no one to run with in the dark!). I then started 12 week program for half marathon training. Got to beginning of week 2 and then came down with nasty chest infection, which I have just finished a course of antibiotics for. I haven't run for two weeks. Should I basically just start from scratch, or see how I get on. I still feel a bit chesty, but it's driving me crazy not running, and I don't want to undo all of my hard work Thanks!
