Most runners train hard and plateau. Coach Glitch is a diagnostic system that finds what's actually breaking down — and tells you what to fix. Not a pace calculator. Not a generic plan. A diagnosis.
// Built by a runner who has made every mistake in this system — and figured out why each one happened.
Answer 8 questions about your training. Get your primary constraint identified, one supporting data point, and one action to take this week — before we ask for anything.
Six principles that govern every Coach Glitch diagnosis and every training decision. Not rules to memorize. A framework that makes training legible.
Not calculators. Tools that encode coaching judgment and tell you what to change — not just what the math says.
Your primary training limiter, supporting evidence, and one action this week. The full report hits your inbox. Free.
Pace plan by segment, fuel schedule, weather adjustment, A/B/C goals, abort conditions. Everything at the start line.
Carbs, fluid, sodium, caffeine — timed and dosed for your body, conditions, and gut tolerance. Plus a gut training progression.
Most runners turn threshold into a race. Audit your last session and find out what's actually happening to intensity.
ASCEND-adjusted training zones from your actual race data. Not VDOT. Not arbitrary percentages. Calibrated to you.
Temperature, wind, humidity, workout type. Exact kit recommendation with heat management and effort adjustment notes.
A 10-part series on how real fitness gets built — and why most runners are doing it wrong. Base. Intensity. Recovery. Race day. In that order.
Lifelong runner, former high school cross country and track coach, and someone who has spent years studying why training works when it actually works. Ryan ran cross country and track from middle school through high school, and since then has finished seven 50Ks and a 50-miler — plus multiple high-mileage years back to back. He knows what long-term progression, durability, and accumulated fatigue actually feel like from the inside.
He built Coach Glitch because he got tired of training advice that assumes the same inputs should produce the same result for every runner. The goal is simple: look at what you're actually doing, find where the system is breaking down, and give you a clear training decision — not another generic plan or a calculator that spits out numbers and calls it coaching.
The free Glitch Training Audit is where most runners start. Eight questions. A real diagnosis. No email wall before the answer.
Run the Free Audit →High-touch human coaching when you need more than a diagnosis. Limited availability.
Learn More →An AI running coach built on real methodology — Lydiard, Daniels, Seiler, Canova — and the training experience of someone who has actually run ultras. Sarcastic by design. Effective by architecture.
The ASCEND system behind Coach Glitch is a periodization framework built by a competitive distance runner and coach. The AI encodes coaching judgment — not just math. The diagnosis it returns is the same reasoning a coach would apply to the same inputs.
Glitch identifies your primary training constraint, shows you the evidence it used, and gives you one action to take this week — before asking for anything. The full report with secondary findings and priority changes is delivered by email.
No. The tools use RPE, training history, and performance patterns. A meter improves precision if you have one. It is not required. The audit is designed around inputs any runner can answer accurately.
A pace calculator takes a race result and outputs numbers. Coach Glitch takes your training pattern and outputs a diagnosis — what's limiting you, why, and what to change. The difference is the same as the difference between a thermometer and a doctor.
ASCEND is the methodology that governs every Coach Glitch diagnosis. Six principles in order: Aerobic first, Specificity, Calibrate, Economy weekly, Never break, Data plus feel. Most runners are violating at least two of them. The audit tells you which ones.
No cadence promises. No newsletter spam. The next piece when it's done — and occasional tool drops from Coach Glitch.
