I am almost 40 and have decided that I want to run a 5K. I have never ran a 5K before and want to scratch it off my bucket list. I am in ok shape, not the best though. How long do you think it will take me to get my body up to running the 5K? If I am running once a day now and increase to twice a day I think that I can get my body in shape for the run faster. I was hoping to be ready for the run in December. Think it's possible?
