ASCEND is the methodology underneath every Coach Glitch diagnosis. Six principles that determine how training decisions get made — in order of priority, not preference. Most runners violate at least two of them. The audit tells you which ones.
Base before speed. Always. The aerobic system is the foundation that every other quality sits on. Build it before you try to sharpen it.
This isn't a suggestion to run slow forever. It's a sequencing principle. Speed work done before the aerobic foundation can support it produces fitness that doesn't last and injury risk that does. Zone 2 isn't boring — it's the most important work most runners under-dose.
Training demands grow toward race day. Early weeks are general. Final weeks are specific. Reversing this order is one of the most common training mistakes.
Race-specific work — goal pace, race terrain, race duration — earns its place in training. It doesn't start there. A runner 16 weeks from a marathon doing race-pace intervals in week 2 is spending fitness they don't have yet on specificity that isn't earned yet.
Training zones recalibrate every 4–6 weeks. Fitness changes. If your zones don't change with it, you're training with outdated data.
The runner who set their zones from a race six months ago and hasn't reassessed is running easy runs that are no longer easy, and threshold sessions that are no longer at threshold. Calibration is not optional maintenance. It's how the system stays honest.
Strides, hills, or speed work belong in every training week. Running economy is a trainable variable — and most distance runners under-train it.
Economy work doesn't mean track sessions. It means regular neuromuscular stimulation — short, fast, controlled efforts that maintain stride mechanics and contact-time efficiency. 4×20 seconds of relaxed strides after an easy run. A short hill circuit. Non-negotiable.
Recovery weeks, down weeks, and deload phases are training. They're not weakness, not a sign of inadequate fitness, not optional.
Adaptation happens during recovery, not during the stimulus. A runner who strings together 12 consecutive hard weeks without a planned reduction is not building fitness — they're accumulating fatigue they'll eventually be forced to pay back. ASCEND plans every fourth week as a recovery week. The body doesn't negotiate.
Your watch and your body outrank your ambition. Both inputs matter equally. Neither is sufficient alone.
Data without feel produces runners who ignore warning signals because the numbers look fine. Feel without data produces runners who drift into Zone 3 on every easy run because it "didn't feel that hard." ASCEND uses HR caps, pace alerts, and RPE as a system — not as individual metrics to be selectively honored when convenient.
The Glitch Training Audit diagnoses which ASCEND principles your current training is violating — and tells you what to change first.
