Build from a comfortable 5K to your first 13.1 miles with three runs and steady BodyBuddy check-ins each week.
Twelve Week Schedule Keep a rest day between runs, with two easy runs during the week and one long run on the weekend.
Week 1 Week 2 Week 3 Week 4 Week 5 Week 6 Week 7 Week 8 Week 9 Week 10 Week 11 Week 12 Run Each Session Use the same calm routine for every run and protect the recovery built into the plan.
Bookend Every Run Start with a five-minute brisk walk and finish with another five-minute brisk walk.
Keep Easy Conversational Run slowly enough to speak in full sentences, and make the long run your slowest run of the week.
Recover After Pickups Run each pickup a little faster than easy for one minute, then return to easy until your breath settles.
Honor Lighter Weeks Keep weeks 4 and 7 light even when you feel strong so your legs can catch up.
Practice Race Fuel On every run over an hour, use the water and food you plan to have on race day.
Repeat When Needed Repeat a hard week and move the race date back if you need more time.
Check In Rhythm BodyBuddy follows each run, remembers useful patterns, and helps you make the weekly repeat-or-progress decision.
Share Starting Details On day one, send your longest recent run and half marathon date.
Check In Twice Name the planned run that morning, then report the miles and how it felt that evening.
Log Long Run Fuel From week 6, report what you ate and drank before and during each long run over an hour.
Review Every Sunday Look back at the week, revisit recurring aches, and decide whether to move up or repeat.
Reuse What Worked BodyBuddy remembers successful long-run food and drink so race morning uses a breakfast you already tested.
Prepare For Race Day During race week, BodyBuddy explains the short runs, then asks about your departure time and food the night before.
Starting Point Ready To Begin This plan fits someone who can run a 5K or 30 minutes without stopping and wants to finish a first half marathon.
Leave Some Room The schedule lasts 12 weeks and can accommodate repeating one or two weeks.
