For Beginning & Experienced Runners
Because this training plan spreads out the weekly and long runs over five months, it can be used by runners who are attempting their first half marathon as well as by someone who's run several halfs already and wants a structured approach to their training. The plan is designed to gradually ease the runner into the process with light, easy runs in the opening weeks, followed by longer, more demanding runs in the middle and later weeks, to help build your fitness level.
Slow Mileage Escalation
The 20-week plan is designed to escalate the mileage you'll run each week more slowly than the other two plans, by bumping up the mileage one week and repeating it the next, and then bumping it up again the following week, and so on. This will help you develop both the physical stamina and the mental confidence that you'll be able to complete 13.1 miles by showing you, very slowly, that you really can do it -- the mileage doesn't increase dramatically from week to week, we just add one mile onto the weekly long runs each week.
Remember also to get plenty of rest on the days you don't run, or consider cross-training such as strength exercises, to give your legs ample time to rest and replenish, especially after your long runs.
Time Your Long Runs With Your Race
The schedule above places the weekly long run on Saturday, followed by a usually much shorter quick run (or walk) on Sunday. Feel free to swap these if the race you've signed up for falls on a Sunday; I've always found that it's best to do your long runs on the day you'll actually run your race, to allow your body to get used to the rhythm of the short run/long run each week.
