AB  - The professionalization of any sport must include an appreciation for how and 
      where nutrition can positively affect training adaptation and/or competition 
      performance. Furthermore, there is an ever-increasing importance of nutrition in 
      sports that feature very high training volumes and are of a long enough duration 
      that both glycogen and fluid balance can limit performance. Indeed, modern 
      marathon training programs and racing satisfy these criteria and are uniquely 
      suited to benefit from nutritional interventions. Given that muscle glycogen is 
      limiting during a 2-h marathon, optimizing carbohydrate (CHO) intake and delivery 
      is of maximal importance. Furthermore, the last 60 y of marathon performance have 
      seen lighter and smaller marathoners, which enhances running economy and heat 
      dissipation and increases CHO delivery per kg body mass. Finally, periodically 
      training under conditions of low CHO availability (eg, low muscle glycogen) or 
      periods of mild fluid restriction may actually further enhance the adaptive 
      responses to training. Accordingly, this commentary highlights these key 
      nutrition and hydration interventions that have emerged over the last several 
      years and explores how they may assist in world-class marathon performance.
