Possible reasons why one might fail to complete a full marathon would include physical exhaustion, dehydration, injury, lack of training, poor nutrition, or simply not having the mental fortitude to push through to the end. Additionally, environmental factors such as extreme heat or cold, or even a sudden change in the terrain can contribute to a runner’s inability to finish the race.

Dehydration is a common problem for marathon runners & Poor nutrition is a detrimental effect. The body loses fluids through sweat during the run & poor nutrition can also lead to an inadequate energy supply, which can result decrease in performance. This can lead to fatigue, dehydration, muscle cramps, heat exhaustion & other symptoms.

To prevent dehydration, runners should drink plenty of fluids before, during & after the race. This can include water, natural drinks, sports drinks, electrolyte drinks or other beverages. Furthermore, lack of nutrition can lead to an increased risk of injury due to an inability to properly recover from the stress of the marathon. To ensure optimal performance, it is important to ensure that you are consuming a balanced diet with adequate amounts of carbohydrates, fats & proteins.

Additionally, it is important to stay hydrated throughout the race & to consume electrolytes to help maintain proper hydration. Lastly, it is important to fuel your body with the right nutrients before, during & after the marathon to maximize performance & reduce the risk of injury.

It is important to take the time to properly train & prepare for a marathon. This includes building up your endurance & strength, learning proper running form & technique; & understanding how to fuel & hydrate your body during the race. It is also important to listen to your body & take rest days when needed.

Hence one should practise race hydration during training days, be short or long runs. Also one should ensure good nutrition strategy throughout the training months, to stay adequately stored with required carbs & fats for regular fuelling of the body & protein for constant muscle recovery.

The biggest reason of failure is when one has not practised hydration & nutrition during the training days; & on the race day just begin with nutrition & hydration loading before the race & during the race respectively. Remember, when you treat your body with something new for the first time, there will be a reaction of the body to accept or reject the same; & you don’t want this reaction to be an experience of your race day. Implementing hydration & nutrition directly on the race is one of the big reasons for failure to finish the full marathon.

Hence it is important to train with proper race hydration & nutrition before race day, nutrition on the race day & after the race for a satisfying result.
