Three Disciplines,
One Protocol
The triathlete's problem is cumulative oxygen debt. Swim, bike, run: each discipline adds to the deficit, and by the time you hit the run your aerobic system is already compromised. Nitrate-loaded nitric oxide helps maintain vascular efficiency across all three legs, not just at the gun.
BRP on race morning handles acute nitric oxide priming. Endurance360 loaded for 14 days prior handles the chronic adaptation side: creatine stores, beta-alanine buffering, and adaptogen capacity. For triathletes, this is genuinely a two-product system because the demands are genuinely two-dimensional.
What You Are Actually Taking
Not a proprietary blend. Not “beet powder.”
Every serving delivers a fixed 400mg dietary nitrate dose. Third-party tested, every batch. The label says exactly what's in the canister because that's the only way race-day dosing is predictable.
Nitrate and nitric oxide precursors are not on the USADA prohibited list. Verify via USADA Supplement 411 before your next race.
I built BRP because I got tired of buying beet supplements that never told me the nitrate dose.
I was loading for LOTOJA, my first serious attempt at the course record, and I could not find a single product with standardized numbers I could trust for race planning. Every label said “beet powder” and nothing else. So I standardized it myself: 400mg dietary nitrate per serving, every batch third-party tested, every bottle consistent. I take it 60 minutes before the gun. That approach held the course record. That is the whole pitch.

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)
