  1. The benefits of Coffee before running
    The overwhelming scientific evidence is that caffeine improves running performance, probably by up to 2% in real world conditions. Caffeine does not cause dehydration, or have a negative impact on running in hot or humid conditions.
    The issues with Coffee before running
    While the benefits of caffeine on running performance are well established, the benefits of coffee are not so clear. Some, but not all studies have shown that the benefits of caffeine are lost when taken in coffee. In addition, Coffee can cause some people stomach issues and it can stimulate the lower digestive system, which may be inconvenient. Note that caffeine during exercise reduces the blood flow to the heart, which makes it dangerous for those with coronary artery disease.

    Post run coffee
    Caffeine increases the speed of carbohydrate absorption which can help with glycogen replenishment if taken with quickly digested carbohydrates.
    Other issues with caffeine and coffee

    Obviously taking caffeine can interfere with sleep, and the effects last for many hours.
    Coffee is linked to a lower risk of many cancers and type 2 diabetes

  2. In the studies I’ve read, coffee has been shown to provide a bit of a metabolic advantage if consumed just before a workout. You can’t expect to see anything dramatic, but if you like coffee (and who wouldn’t like a nice freshly brewed cup of premium roast freshly ground pour-over coffee first thing in the morning as a way to get the engine started?) and you’ll have some anyway, have some before your early morning run.
    At least that’s Gord’s version.

  3. In theory, both…. if your GI system can handle it.
    Pre-run: There’s tons of research supporting pre-run caffeinating, citing everything from mobilizing fatty acids and providing energy to lessening your RPE (Rate of Perceived Exertion) to significantly increasing endurance. Personally, I like coffee before my runs or workouts. However, some people experience GI distress when they consume coffee and then exercise, which can be very inconvenient.
    For longer morning runs (>5k or 30+ min) or workouts, many people perform better when they have a very small, easily digestible snack–like a bite or two of banana– to replenish the glycogen lost while sleeping so that they’re getting energy from more than just coffee. Others, myself included, prefer only coffee or water before morning runs.
    The advice I give my clients is to try all the pre-exercise options and pay attention to how their bodies respond and what option provides the best performance.
    Post-run: Caffeine taken with carbs after a run also helps the body replenish glycogen stores more effectively, which makes a shot of cold espresso in your protein shake a good call. (Please note, mixing protein powder into a hot beverage causes it to curdle or clump. Not appetizing.)
    Here are a few sources. There are plenty of others. I think the coffee issue is covered at least two or three times per year in Runner’s World, which is quite often considering it’s bi-monthly publication.,7120,s6-242-301–13105-0,00.html

  4. I always have a small coffee before my runs. I never have coffee after. It works for me but I have heard the opposite as well from fellow runners. So the answer is you must experiment with what suits for you.
    However, I did read an article a few weeks ago claiming that coffee works as a mild pain reliever so thats probably where the advantage comes from when you have your coffee before the run. But remember: hydrate hydrate hydrate.

  5. If i drink coffee or anything containing a high doze of caffeine within 30 minutes after an exercise or workout i just die. Some people are also caffeine sensitive so it could do more damage than good, and as always after a workout you have a higher heart rate and your heart is already worked out, if you add caffeine to that which narrows the blood vessels and arteries you create even more stress for your heart. I would recommend to wait at least an hour or two before drinking coffee after a workout to allow your body to cool down.

  6. I always tell people – experiment. There are a gazillion scientific experiments, and you’ll always find the opposite research for everything. Last time I checked on I saw (on the same page) two articles, one saying that being a little hydrated doesn’t hurt anything and the other saying how much being hydrated at all times counts – both had research to back up their claims.
    What I’m saying is, essentially, have coffee before, and go for a run, see what happens. I can tell you that personally, if I drink (espresso, no milk) less than 30 min before a session (running/mountain biking) I don’t feel so well. If it’s longer than 30 min, I’m good.

  7. It is best to drink coffee in the morning before running. Coffee is very beneficial because Reduced Gall Stones, Risk for Alzheimer’s Disease and Risk for Parkinson’s Disease. It also increases the Cognitive Ability.

  8. Caffeine improves athletic performance, so drink it before (unless contraindicated by health problems).

    Exercise physiologists have studied caffeine’s effects in nearly every iteration: Does it help sprinters? Marathon runners? Cyclists? Rowers? Swimmers? Athletes whose sports involve stopping and starting like tennis players? The answers are yes and yes and yes and yes.

    Starting as long ago as 1978, researchers have been publishing caffeine studies. And in study after study, they concluded that caffeine actually does improve performance. In fact, some experts, like Dr. Mark Tarnopolsky of McMaster University in Canada, are just incredulous that anyone could even ask if caffeine has a performance effect.

    “There is so much data on this that it’s unbelievable,” he said. “It’s just unequivocal that caffeine improves performance. It’s been shown in well-respected labs in multiple places around the world.”
