Whether it's your first time in a racing bib or you just need a little refresher on those 10-miler training runs, we've got a half-marathon training schedule that will get you across the finish line. Join the ranks: The half marathon currently has the highest percentage of women of any U.S. road distance—60 percent of competitors are now female (in 1985, just 20 percent of competitors were!). If it seems like everyone and her sister is doing a half marathon, there’s a reason: a total of 1.9 million runners finished a half marathon in the U.S. in 2016, according to Running USA's annual report.

So SHAPE asked running coach Brendan Cournane to give us two plans. Follow his expert advice (he's completed marathons in all 50 states!), get started on this half-marathon training plan, and you'll be feeling confident at the start and ready to finish strong come race day. Try it: 13.1 will look great on you! (In case you're still deciding whether to sign up, here are 30 Convincing Reasons to Become a Runner.)

If you've been running three or so miles three times a week (about 10 miles/week), click here for a half-marathon training schedule for regular runners. In 12 weeks, you'll safely increase your mileage so you can handle the whole 13.1. Plus, you get two days of rest and two days of cross training every week. If you're a first timer, keep reading for a beginner's plan.

If you're new to running and/or haven't been working out regularly in the last six months, opt for this half marathon training schedule (scroll down to see the full plan)This 12-week half-marathon training program starts with periods of walking interspersed with periods of running. Your longest walk/run the first week is four miles, and you work up to race-ready over three months. Bonus: Sundays and Fridays are rest days!

If you're a true running first-timer, follow the (A) time periods; if you've been hitting the pavement a couple times a week, go for the (B) options.

FYI: The number to the left of the "/" indicates the length of time (in minutes) to run, while the number to the right of the "/" indicates the length of time (in minutes) to walk. For example, the (A) workout for the first week of the schedule reads 3/2, which means you should run for 3 minutes, walk for 2 minutes. The workouts for running on Mondays and Wednesdays are time-based. For example, Monday of the first week reads 30 - 36 minutes. If you're following the (A) schedule, you'd run-walk for 30 minutes; if you're doing the (B) plan, you'd run-walk for 36 minutes.The mileage listed is the max distance you should go, so for Monday of Week 1, you'd run/walk for three miles or 30/36 minutes, whichever comes first.

How to Read the Workout Key

Cross train: Not a weight-bearing activity. Examples are biking, swimming, rowing, or elliptical trainer. You want to maintain and build on your aerobic fitness, while also giving your body a rest from the wear and tear of running. (Here's the complete guide to cross-training for runners.)
Easy run: This is a recovery run, so if you're training with a heart rate monitor, stay in the 65 to 70 percent zone. 
Long: This is a long, slow distance run, also known as a 'fat burning run'; keep a pace that makes it easy to maintain a conversation. (These tips will help you crush your long runs.)
