I'm a slow runner planning my first half marathon in the spring. I was expecting to use a 12 week training plan.
Every plan I've seen for 2hr 30 plus mins target times limits the long run to 10 miles. Is this for sound training reasons or because they expect runners at these times to want to train the minimum to get around?
I ran long runs of 13k for my last 10k race and have done a few 11 mile runs before an upcoming 10 mile race. I always thought this was the wise thing to do.
Should I be planning to run 15 miles or so in HM training, or limit it to 10, which I can already do?
