ONE SYSTEM · THE ENTIRE JOURNEY
From measurement to execution.
The same training logic follows every decision — from your baseline pace to the final race split.
One shared foundation
MLSS/LT becomes the baseline for zones, training plans and predictions.
No gaps between zones
17 narrow zones and 43 levels for genuinely targeted intensity.
A strategy that sees the conditions
Time, temperature, humidity, wind and course profile are calculated together.
The actual course
A GPX map with distance, elevation and running direction for every segment.
Pace × elevation
The elevation profile becomes an actionable race-effort plan.
MORE THAN A CALCULATOR
Every tool speaks the same language.
Route-based plans
GPX data shapes the gradients, elevation and training demands of a specific course.
Race strategy
Likely pace range and splits adjusted for terrain, conditions and your preferred start scenario.
Climate & wind

FIT & PDF
Training and race-split exports designed to move the plan beyond the screen.
Fueling
Carbohydrate loading and marathon fueling calculations with a practical timeline.
