The 8 day hot weather protocol
A simple, structured 8-day routine designed to support your body ahead of hot weather events. Take one sachet daily for 8 days, with the final dose on race morning. Follow the clear daily guidance for best results.
What it is
A precision thermoregulation formula engineered to help your body manage heat stress during sustained effort. Formulated with purpose — clean, bioavailable ingredients and no unnecessary fillers, built to support core temperature control when conditions are demanding and margins are tight.
- Marathon and ultra runners facing warm race days
- Triathletes and Ironman athletes competing in hot climates
- HYROX and functional endurance competitors
- Cyclists and outdoor athletes training in summer conditions
4,000 mg L-Taurine — clinical-level dosing per serving
3 electrolytes — potassium, calcium & magnesium in one formula
0 kcal — pure function, zero sugar, zero filler
Why CoreCtrl™ Matters:
Core temperature is one of the most underestimated limiters in endurance sport. As heat rises, blood flow shifts away from working muscles to cool your body — and pace drops. CoreCtrl is formulated to support your body's natural thermoregulation, helping you sustain output for longer in heat, humidity, and high-intensity conditions. Less heat stress. More time at threshold.
Facts
Quality Ingredients:
L-Taurine, Acid (Citric Acid), Potassium Citrate, Calcium Citrate, Flavourings, Himalayan Rock Salt, Magnesium Citrate, Anti-caking Agent (Silica, from Bamboo), Sweetener (Steviol Glycosides from Stevia), Black Pepper Extract (Piper nigrum).
No colours. No unnecessary fillers. No fibre.
Why this formula?
-
During exercise, approximately 75–80% of energy is released as
heat. -
When heat production exceeds the bodyʼs ability to
dissipate it, performance becomes constrained, not by fitness or
motivation, but by protective physiological limits. -
Research shows that targeted support of thermoregulation can:
- Increase sweat response
- Improve evaporative heat loss
- Reduce internal heat storage
- Extend sustainable performance in hot conditions
-
The result isnʼt a spike. Itʼs control, consistency, and resilience
when heat would normally become the limiter.
Who is this for?
- CoreCtrl is for endurance athletes who train or race in heat, humidity, or high-intensity conditions — and want to stay sharp longer.
- If you've ever felt your pace drop in the second half of a hot run, cramped on the bike in warm weather, or struggled to recover after a heat session, CoreCtrl was built for you.
- Triathletes, runners, and cyclists who push hard and can't afford heat to be the reason they fall short.
