The Runner's
Threshold Edge
Stop guessing your dosing. Use the clinical plan trusted by course record holders to increase oxygen delivery and buffer lactic acid during your hardest efforts.
Built for Elite Competition
No fillers. No proprietary blends. Trusted by elite endurance athletes, including a LOTOJA Classic course record holder.
The Runner Loading Plan
Optimized for Marathon / Half Marathon. See the full 7-phase plan for all distances and stacking options.
| Phase | Timing | Dose | Notes |
|---|---|---|---|
| Base Loading | 3 days pre-race, AM + PM | 2 servings per day | Saturates muscle tissue before taper |
| Race Eve | Evening before race | 1 serving | Final top-up; do not skip sleep for this |
| Race Morning | 60 to 90 min before gun | 1 serving | Peak nitric oxide aligns with starting pace |
| Late Race (optional) | Mile 18 to 20 for 4+ hour finish | 1 serving | Extends vasodilation through the final miles; test in training first |
What to Avoid on Race Day
- XAntibacterial mouthwash on race morning (kills the oral bacteria that convert nitrate to nitric oxide)
- XProton pump inhibitors (PPIs) within 2 hours of dosing (reduce stomach acid needed for conversion)
- XAlcohol the evening before (impairs nitric oxide synthesis)
- XHigh-nitrate foods (beets, spinach, arugula) in the 24 hours before if not part of loading plan (unpredictable nitrate stacking)
