01
Predict finish time based on real power
Estimate realistic outcomes from actual effort instead of generic pacing assumptions.
Decision intelligence for ultra-endurance athletes.
Predict your limits before you reach them.
Simulate your race, manage fatigue, and execute with confidence.
Positioning
This is not a tracker. Not a coach.
It is a decision system for ultra-endurance athletes racing deep into fatigue, uncertainty, and collapse risk.
Core Principle
At some point, your body stops making good decisions. Redline Lab helps you see that point before race day does.
01
simulate your race
02
manage fatigue
03
execute with confidence
System
At some point, your body stops making good decisions.
In ultra-endurance events, performance is not just fitness. It is strategy under fatigue, sleep deprivation, and energy collapse. Most athletes guess. Guessing leads to bonking, overpacing, or quitting.
02
Model fatigue and power decay over hours
See how sustainable output falls as accumulated stress starts shaping every decision.
03
Plan fueling, sleep, stops, and bonk risk
Visualize collapse before it happens so your race strategy can absorb reality.
Science
Built on real physiological models.
Redline Lab is not based on heuristics. It models how your body actually behaves under stress.
01
Exponential fatigue decay
Performance drops are modeled as stress compounds rather than appearing out of nowhere.
02
Glycogen depletion and bonk risk
Energy availability becomes part of the plan, not a problem you only notice too late.
03
W' balance and anaerobic capacity
Short-term effort capacity is folded into long-duration strategy instead of treated separately.
04
Hydration, thermal stress, and sleep loss
Heat, recovery, and sleep deprivation effects are visible before they start distorting decisions.
Adaptive Support
A partner that understands your data.
Ask questions. Adjust your plan. The system adapts based on your training and your race strategy.
AI Performance Coach
Race World
Designed for the road beyond the easy decisions.
The platform exists for the part of endurance racing where scenery is still beautiful, but judgment starts to fade.
