For sessions where intensity is high, breathing gets heavy, and quick recovery between efforts is critical:

Beta-alanine: Supports lactate buffering during high-intensity efforts, helping reduce muscle burn so you can sustain pace across intervals.

Nitrates (from beet juice): Support oxygen delivery and muscle efficiency during hard efforts, helping you hit target paces and repeats with less drop-off.

Electrolytes: Help maintain neuromuscular function and hydration so fatigue doesn’t compound as quickly.

For when holding pace gets harder, dehydration shows up as cramps or heavy legs, and how you recover matters just as much as the run:

Water and electrolytes: Replacing fluids and electrolytes helps maintain hydration status, reduce cramping, and preserve mental clarity as fatigue accumulates.

Carbohydrates: Regular carbohydrate intake helps sustain pace, delays fatigue, and supports steady pacing as glycogen stores run low.

Protein: Provides the amino acids needed to support muscle repair and adaptation so you can recover effectively between sessions.

For when efforts feel harder to repeat and progress depends on how well you recover between them:

Creatine: Supports repeatable training output and strength maintenance so sessions stay productive even as fatigue builds.

HMB: Helps reduce muscle damage during heavy training periods, supporting recovery and consistency across weeks.

Beta-alanine: Buffers lactic acid during high-intensity efforts, helping you tolerate harder efforts as work stacks up.

Nitrates (from beet juice): Support increased blood flow and muscle efficiency, helping reduce the perceived cost of hard efforts.

For the final week of training and the race itself, when execution matters more than adaptation:

Carbohydrates: Provide readily available energy to support sustained pace and decisive efforts when it counts.

Electrolytes: Help maintain hydration status and neuromuscular function so performance doesn’t drift late in the race.

Nitrates (from beet juice): Support oxygen efficiency and exercise economy, helping you perform at a high level without changing how you race.

For after hard sessions, heavy training, and races when soreness lingers, recovery limits consistency, and injury risk increases:

Protein: Provides the building blocks for muscle repair and adaptation so recovery supports ongoing training.

Creatine: Supports muscle recovery and strength maintenance, especially during high training loads.

HMB: Helps reduce muscle damage and supports tissue recovery when training stress is high.

Tart cherry: Supports recovery by helping manage soreness and inflammation following hard efforts.
