This year has been a real bummer for me in that sense. I used to run for around 5 to 10km (depending on the time I had) at least 3 times a week since I've been 16. It helped me through a lot of hard times, and helped me regulate my mood and food disorder... The only times before my backs problems when I stopped running were during my last 3 months of pregnancy and the 3 months after giving birth because I was in no state to... But for the last 3 months of each pregnancy I walked 5 to 10 km a dayNo running for over a year and you still managed 5km! Kudos!!
