A half-marathon is a running event over a distance of 13.1 miles or 21.1km. It is a hugely popular distance, and its popularity is only growing. There are over 2,800 half-marathons in the USA each year, with over 1.9 million competitors taking part. Most major American cities host a half-marathon race, and these events often attract big crowds and a festival atmosphere. Other events are more rural, making the most of America's stunning scenery. They can take place along coasts, across deserts, or in mountains and national parks. Wherever you are, there are sure to be breathtaking views to take your mind off the running! People running their first half-marathon might want to aim for under 2 hours, while those who are experienced runners can set themselves the prestigious challenge of running a half marathon in under an hour and a half (90 minutes). A half-marathon tends to burn anywhere between 1,000 and 2,000 calories, so it's a great workout.
