That being said, my coffee and food consumption has sky rocketed lately. While it's not encouraged by the running community, my go-to food before a run is cake. Yes, cake. It's high in calories and that sugar boost is exactly what I need to go my fastest.
Most runners prefer to get that boost from caffeine right before a run. There are many different views on if caffeine can enhance sport performance, and while I am no expert, from what I have read and experienced, caffeine can definitely help push you through to the finish line. Most runners and running magazines agree and encourage caffeine consumption, telling readers to go ahead and enjoy that cup of coffee. However, what irritates me is that while these articles encourage runners to drink coffee, they do no warn against the risk of dehydration.
Runners know they need carbs postrun to rebuild their glycogen stores, but a recent study suggests caffeine may also enhance recovery. Cyclists rode hard for two consecutive days to drain their glycogen stores. They then drank a carb beverage with or without caffeine. Researchers found that having a drink with caffeine rebuilds glycogen stores 66 percent more than a carb-only drink.
