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 Triathlete Loading Plan
Optimized for Olympic / 70.3 / Full Ironman. See the full 7-phase plan for all distances and stacking options.
| Phase | Timing | Dose | Notes |
|---|---|---|---|
| Base Loading | 3 days pre-race (Olympic/70.3) or 5 days (Ironman), AM + PM | 2 servings per day | Longer block for longer race; stacks with Endurance360 creatine and beta-alanine loading |
| Race Eve | Evening before | 1 serving | Take with your normal carb-loading dinner |
| Race Morning | 60 to 75 min before swim start | 1 serving | Enters peak effect before T1; mix with water, not a caffeinated drink |
| Bike Leg (Ironman only) | Around hour 3 on the bike | 1 serving | Extends vasodilation through the run; dissolve in a spare nutrition bottle |
What to Avoid on Race Day
- XAntibacterial mouthwash on race morning (blocks the oral nitrate-to-nitrite-to-nitric oxide pathway)
- XProton pump inhibitors within 2 hours of dosing
- XAlcohol the night before (impairs nitric oxide synthesis)
- XMixing Beetroot Pro with a caffeine gel or sports drink that contains citric acid (drops pH, reduces conversion efficiency)
