REACH PEAK SPEED & HIGH AEROBIC LEVELS WITH A DAILY SUB-THRESHOLD RUNNING PLAN. GET FITTER & FASTER WITHOUT THE BURNOUT.
Unlock your true potential and build a bulletproof aerobic engine with loop28. Most runners plateau because they train too hard on easy days and not precisely enough on hard days. As a comprehensive run coach in your pocket, loop28 eliminates the guesswork, bringing elite-level methodology based on the Norwegian Singles to the everyday enthusiast.
Whether you are training to run fast for a local race or simply looking for a better run planner, our app provides a structured run training plan designed to maximize your speed and endurance while actively protecting you from burnout.
■ MASTER YOUR SPEED
Whether you are a 5k runner chasing a new PB or a 10k runner looking to solidify a daily habit, loop28 creates your perfect path:
• PRECISION TRAINING: Get exact targets for pace and heart rate. If you prefer to run 5k or more by feel, simply toggle pace off and focus entirely on the effort.
• PROVEN WORKOUTS: Access elite-tested sessions like $6 \times 5$ minutes or $6 \times 1$ km, perfectly balanced with recovery miles and essential long runs. It's the professional way to train for 5k and beyond.
• VISUAL PROGRESS: Use our built-in run tracker to monitor your journey with a sleek visual calendar and keep your momentum alive with integrated running streaks.
■ DAILY RUNNING PLANS FOR AMBITIOUS RUNNERS
If you have already graduated from a couch to 5k program or completed a 0 to 5k challenge and feel like you’ve hit a plateau, loop28 is your solution. We go beyond the standard 5k training to help you bridge the gap from 5k to 10k and eventually tackle half marathon training.
Every session in your daily run training has a definitive purpose:
· INTERVAL DAYS: Halved "Norwegian Doubles" sessions designed for training to run faster.
· EASY MILES: Strategic recovery sessions to keep your energy high and your legs fresh.
· BASE BUILDING: (Premium) Specialized half marathon trainer modes and 10k trainer plans for those targeting longer events and higher weekly mileage.
■ FREE FOR ALL RUNNERS
We believe in the power of the daily 5k run. While we offer more sophistication than a typical 5k run trainer or a local run club, the core loop28 experience—including your daily plan and streak tracking—is free for all runners.
Whether you are a 5k runner or preparing for high-stakes running racing, our platform scales with you.

WHAT IS NORWEGIAN SINGLES TRAINING?
The "Norwegian" method has recently revolutionized running, popularized by Olympic champions who utilize "Double Threshold" sessions. Norwegian Singles adapts this high-level science for the ambitious athlete. By focusing on a single, high-quality sub threshold session, you hit the physiological "sweet spot": intense enough to trigger massive aerobic gains, but controlled enough to ensure you can recover and go again tomorrow. It is the secret to building elite speed through sustainable, daily consistency, making it the ultimate run trainer for those moving beyond a basic running app for beginners.
WHY NORWEGIAN SINGLES?
The world’s best at race running use these principles to dominate the global stage, and now you can too. By utilizing sub threshold training, loop28 helps you build the speed of a pro with the recovery of a smart athlete. You’ll develop a massive aerobic base without the soul-crushing fatigue of traditional "all-out" intervals. It's the evolution of the standard run plan, focusing on quality over "junk miles."
