I completed my first 10K on a dare. In a year, I ran a half-marathon. Another year later, I finished a marathon race. Today I run 2 marathons a year and a half-marathon every week.
On average, it takes 10-20 seconds to run 100 meters, depending on various factors such as age, fitness level, and running technique. The current world record for 100 meters is 9.58 seconds, set by Usain Bolt in 2009.
The average time to run 20 miles for seasoned runners is around 2.5 to 3 hours. For beginners, completing 20 miles without a stop is a notable milestone, regardless of the time taken.
