Hi there
I also would like to take part in a half marathon because I don't have the time to train for full. Yesterday I ran 21 km but with lots od ascending and I know that marathons don't have hills or at least not as big.
Maybe now I should work on speed and do sprints because this is what I lack. I know running only once a week is not enough but my greatest love is mountain biking so I ride at least 5 times a week. Or maybe I should incorporate at least one more training during the week.
What is more, I'm not sure what marathon I will run and when I just want to do it
