The time it takes to run 1 kilometer (1k) varies widely depending on fitness level, age, and running experience:

• Beginners typically run 1k in about 6 to 8 minutes.
• Recreational runners average 5 to 6 minutes per 1k.
• Experienced runners usually complete 1k in 4 to 5 minutes.
• Elite runners can run 1k in under 3 minutes

For example, a good average 1k time across all ages and genders is around 4:11, with the fastest recorded times near 2:21

. If you are starting out, completing 1k without stopping is a solid achievement, and with consistent training, your time will improve. If you meant running a 10k (6.2 miles), beginners often take about 1 hour to 1 hour 15 minutes to complete it, while advanced runners can finish in around 45 minutes

. In summary, how long it takes to run "a k" depends on whether you mean 1k or 10k and your running level, but for 1k expect anywhere from under 3 minutes (elite) to about 8 minutes (beginner), and for 10k expect roughly 1 hour for beginners
