How to run a half marathon
Train For A Half Marathon (13.1 Miles)
Here is the ideal half marathon training schedule. You will need to run at least 10 miles once a week for at least a few months before the event. An ideal schedule would be to run 7 miles Tuesday and Thursday and 5 miles on Monday, Wednesday and Friday. On Sunday go for a nice long run of 10 to 13 miles.
Write down approximately what you think your daily mileage is right now. Total this up to get your weekly mileage. To stay injury free you should not increase this total more than 10 per-cent a week.
