As marathon season builds, performance nutrition brand Innermost is spotlighting The Marathon Stack –a practical, science-led approach to fuelling endurance training and race day through a combination of its core products.
Designed to support runners across the full lifecycle of performance from pre-run energy to post-run recovery, the stack brings together targeted formulations that address the key physical demands of long-distance running: sustained energy, hydration balance, muscle repair and digestive support.
Pre-Run: The Energy Booster
Ahead of a run, The Energy Booster is designed to support both physical endurance and mental focus – two factors that become increasingly important over longer distances. Combining natural caffeine sources such as green tea extract with ingredients like L-carnitine and B vitamins, the formulation works to support energy metabolism while helping to reduce fatigue. The result is a more sustained, even release of energy, making it particularly suited to long runs where pacing and consistency are key.
During: The Hydrate Blend
As distances increase, hydration becomes a defining factor in performance. The Hydrate Blend is formulated to go beyond basic hydration, delivering a balance of electrolytes including sodium, potassium and magnesium to help maintain fluid levels and support muscle function. Designed to be easily absorbed during exercise, it helps counteract the effects of sweat loss, supporting endurance while reducing the likelihood of cramping and energy dips over time.
Post-Run: The Strong Protein + Recover Capsules
The Strong Protein
Post-run, the emphasis shifts to repair and recovery – an essential but often overlooked part of marathon training. The Strong Protein provides a high-quality, plant-based protein blend formulated to support muscle repair and adaptation following endurance exercise. By delivering essential amino acids, it helps the body rebuild and strengthen between sessions, supporting consistency across a training block.
Alongside this, The Recover Capsules provide more targeted support for the body’s recovery processes. Combining key vitamins, minerals and functional compounds, the formulation is designed to help reduce fatigue, support immune function and assist the body in adapting to sustained physical stress – particularly valuable during periods of high training volume.
Targeted, Science-Led Formulations
Innermost’s products are designed around specific functional outcomes, using carefully selected ingredients to support key areas of performance – from energy metabolism and hydration to muscle recovery and fatigue reduction.
