A 10K run is 10 kilometers long, which is the equivalent of 6.2 miles. It's double the distance of a 5K, which is another popular race distance. If you've never run a race before, a 5K race is a good introduction to road racing for beginners.
It may be: the number 10,000; 10k run which is a common running race distance; 10k Plan which was aimed to attract 10,000 new residents to Oakland and was created by Jerry Brown.
Because you will build up a lot more endurance so that you can run faster for a longer period of time. Also, the longer your longest run is, the shorter the race distance will seem.
It's perfectly OK to walk in most 10k races (although more people will be running than walking), especially if the race is titled "10k run/walk." However, if it's specifically called a "10k run," you might want to email the race organizers and ask if it's OK to walk. Sometimes a race has a "5k run/walk" and a "10k run," meaning that you can run and/or walk in the 5k but can only run in the 10k. Basically, it's most likely that walking is totally fine. It's not like they can disqualify you for walking, anyway.
The answer is actually in the question. 10k is and abbreviation of ten kilometres, therefore a 10k race is 10 kilometres long.
