I've just agreed with my DSis that I will run a half marathon with her in October. I am now petrified as to how on earth I am going to manage this. She is super fit - does triathlons etc all the time - but I'm not!
I do two half hour high intensity interval training a week but don't do any running at all. I could probably half run half walk a 5k at the moment to give an idea of fitness.
Can anyone help me work out a training plan which is going to get me to stage where I can complete a half marathon in October please?
