Past about 90 minutes of hard effort, if carbohydrate isn’t keeping up, your body can start drawing on muscle protein for fuel. QC Stamina is a sachet of amino acid support built to be taken during the race itself, not after it — light, quick to digest, and easy on the stomach.
Why protein during a race, not just after
Long-distance running or cycling causes metabolic stress and micro-damage to muscle protein. Consuming protein supports the repair process and helps you adapt to the training load.
When carbohydrate stores drop — typically past around 90 minutes of sustained exercise — the body can start using amino acids from muscle tissue for energy instead. Providing protein during the event helps reduce how much of that happens.
General sports nutrition guidance puts daily protein intake for endurance athletes around 1.8 g/kg body weight, with higher needs (around 2.0 g/kg) on low-carb or high-intensity training days. Post-exercise protein, roughly 0.5 g/kg, supports recovery and repair on top of that.
What makes QC Stamina different from a recovery shake
- Built for race-day use, not a post-workout shake — light and quick to digest mid-race.
- Helps sustain muscle output during long efforts when carbs alone may not be enough.
- Portable sachets — one every 2–3 hours — built to sit easily in a drop bag or race vest.
It’s protein aimed at a specific job: keeping amino acids available during a long race, once your carbohydrate intake is already covered. It doesn’t replace getting carbs, fluids and pacing right first — those still come first in any race plan.
QC Stamina fills a specific niche: protein support during long endurance efforts, built to digest easily on the move.
