About
Built on a methodology.
Not a template.
Threshold translates the Norwegian Method into training plans that hold up under real schedules, real fatigue, and real injury risk.
What we stand for
Three commitments, enforced in every release.
Nothing invented
Every training decision the app makes traces back to a published source — the Norwegian Method, published VDOT tables, and peer-reviewed sports science. Where the literature is debated, Threshold is conservative.
Safety is not optional
Volume cap at 10% per week. No session more than 30% longer than recent history. Deload every 3–4 weeks. Long runs capped at 35% of weekly volume. The rules engine refuses to let you break them, even if you ask.
Method translated cleanly
The Norwegian Method has been practiced by Norwegian distance coaches for decades but was rarely available in app form without being diluted. Threshold keeps the framework intact and makes it trainable with race data, watch data, and structured feedback.
Honest scope
What Threshold isn't.
Not a coach. Threshold is a training tool. For race-specific coaching, injury rehabilitation, or performance diagnostics, work with a qualified human coach or sports-medicine professional.
Not medical advice. The app is built on published training science, not clinical protocols. If you have a pre-existing condition or experience pain during training, talk to a healthcare professional first.
Not a celebrity endorsement. We don't claim any specific Olympian uses Threshold. The methodology we implement was developed in Norway and has been used at the elite level for decades. We credit the people whose work it is, and we stay in our lane.
Provenance
Where the plans come from.
The training framework comes from published Norwegian-method coaching principles: frequent controlled threshold work, tight intensity control, polarized easy volume, and block-by-block progression with regular recovery.
Paces are computed using published VDOT tables — a decades-old, publicly available framework for translating race results into training paces.
Safety rules are distilled from mainstream sports-science literature on training load, recovery, and injury risk — the same principles used by reputable coaches worldwide.
Threshold is an independent product. It is not affiliated with, endorsed by, or sponsored by any coach, athlete, federation, or lab.
