The Running Algorithm is your personal running coach in your pocket. Tell us when you're available and we'll handle everything else. All you need to do is run. Most training plans break the moment real life gets in the way. A late meeting, a rough night's sleep, a missed session, and suddenly you're behind and trying to cram. The Running Algorithm works differently. It builds a fully flexible plan around your schedule, then adapts automatically as your week, and your body, changes. ADAPTIVE TRAINING THAT FITS YOUR LIFE Plans are built around the days and times you can actually run. If your plans change, your plan changes with them. No more falling behind, no more guesswork about.how to adjust your training, we handle it for you. TRAIN FOR ANY DISTANCE Whether you're chasing your first 5K, a 10K personal best, a half marathon, or your first full marathon, The Running Algorithm builds the right plan for your goal. Add as many events as you like and we'll plan the training around all of them. No need to cancel and restart plans between events, we remember what you’ve done and use that to build toward your next goal when one finishes. FEEDBACK THAT SHAPES YOUR PLAN After every run, you tell us how it went. The platform uses that feedback to track your freshness and fatigue, then adjusts upcoming sessions so your training always matches how you're feeling and how much time you have. SMART, INJURY-AWARE PROGRESSION Our fatigue model is designed to keep your training sustainable. By balancing hard and easy days intelligently, we help you avoid the back-to-back hard sessions that lead to burnout and injury. This means that you can stay consistent and improve faster. BUILT BY RUNNERS, COACHES AND DATA SCIENTISTS We combine cutting-edge machine learning with custom sessions designed by world-leading experts. The result is a plan that's both scientifically grounded and genuinely personal to you.
