Hi, I started running a year ago. Now, I'm definitely not fast, and I won't be running a marathon anytime soon, however, in November, I was able to run a 5K straight through. I have done the Warrior Dash, and several other 5K's, but November was the last race I did, and I haven't ran since January. When I run, my left foot goes numb, and I start to develop pain in my lower back. I also suffer from shin splints. I know these are typical problems when it come to running, but I am unalbe to run more than the 3 miles. I would like to be able to run a 10k by the time the summer is over, and a half-marathon by next year. I have tried tieing my laces loosely, and stretching thouroughly before and after running. I am looking for any advice on how to reduce the pain so I can run again and up my mileage.
