All the best with Marathon training, Audra. As long as you don't do what I did when training for a marathon back when I was in my early 20s. I ran quite a bit for maybe 8 weeks, but the longest I ran was maybe 12-15km before the race. On marathon day I somehow made it through from start to finish, in 5 and a half hours. So see, you can do anything you set your mind to!! Good luck!!! :)
