Question: does drinking coffee make you run faster?
Answer: Helps you get a faster 5k time Luckily, a group of researchers studied this exact question. Using a 5k race as a test run, the researchers found that runners who used caffeine prior to their 5k race improved by 1.0 to 1.1 percent (this means a 20-minute 5k runner would run 10-13 seconds faster just by using caffeine).
