Lactic Buffer

Bicarb Calculator

Sodium bicarbonate buffers the acid produced in high-intensity efforts, delaying that burning-legs feeling in events from 1–10 minutes or with repeated hard bouts.

• Personalised dose from your body weight
• Capsule count & split-dose plan
• Optimal timing before your event

Oxygen Efficiency

Nitrate Calculator

Dietary nitrate from beetroot boosts nitric oxide, improving blood flow and muscle efficiency — hold the same pace at a lower oxygen cost.

• Daily nitrate target for your body weight
• Loading protocol for race week
• Timing your final dose before the start

Hydration

Electrolyte Calculator

Sweat rate and sodium loss vary hugely between athletes. Match your fluid and electrolyte intake to your conditions, duration and sweat profile to beat cramp and fade.

• Fluid & sodium targets per hour
• Adjusted for heat, duration & intensity
• A practical race-day drink plan

Energy & Fuelling

Carbohydrate Calculator

Your muscles only store around 90 minutes of glycogen. Fuelling with 30–90g of carbs per hour maintains blood glucose and delays fatigue, under-fuelling is why so many fade late in a race.

• Carbs per hour for your duration & intensity
• Whole-session fuelling & energy totals
• Adjusted for a trained, high-carb gut

Recovery

Protein Calculator

Protein taken soon after exercise provides the amino acids to repair and rebuild muscle, around 0.25–0.4g per kg of body weight maximises muscle protein synthesis and speeds recovery between sessions.

• Post-session protein target from your weight
• Matched to easy, standard or hard sessions
• Carb pairing & 30-minute timing window
