The Norwegian running method, adapted to your life. Threshold builds a complete, periodized running plan around your goal, current fitness, training history, and weekly schedule. It applies the principles behind Norwegian threshold training while scaling the dose to your level. This is a connected training plan rather than the same week repeated. Your training moves through base, build, peak, taper, and transition phases, with progressive volume and recovery weeks built in. HOW IT WORKS Tell Threshold about your running background, race goal, available days, and current training. The app creates a multi-week plan with clear warm-ups, intervals, target paces, recoveries, and coaching notes. WHAT YOU GET Adaptive Training Plan Your next sessions and weeks respond to what you actually complete, the effort you report, schedule changes, and missed training. Norwegian Threshold Sessions Controlled threshold work inspired by the Norwegian Method, including double-threshold days when they fit your experience, volume, and recovery capacity. Precise Training Paces Training zones and targets use your race results and current fitness so every easy run, threshold session, and interval workout has a clear purpose. Progressive Training Weeks Volume and intensity develop across real phases. Recovery weeks and guardrails help keep changes measured when your training load increases. Log, Edit, and Adjust Record completed sessions, correct the details later, skip or move a workout, and continue into the next block without losing your history. Coach Chat Ask questions about the plan, report fatigue, and get answers grounded in your completed training and current week. Apple Health Import Connect Apple Health to import completed runs and relevant workout details into your training history. WHO IT IS FOR - Runners preparing for a 5K, 10K, half marathon, marathon, or longer race - Runners who want a structured plan without hiring a full-time coach - Experienced athletes who want to apply Norwegian threshold principles with a practical weekly schedule - Developing runners who need the method scaled to their current training ABOUT THE METHOD Norwegian threshold training centers on accumulating high-quality work near threshold while keeping intensity controlled enough to recover and repeat. Threshold turns those principles into a plan you can understand, complete, and adjust week by week. Threshold provides training guidance and is not medical advice.
