5K | 10K | 15K | Half Marathon | Marathon Ultramarathon What is a good speed?
If you’re new to running, or you’ve never run before, a 5K is a great place to start. But before you add a 5K to your bucket list, you might be wondering: How far is a 5K run really? And how long does it take you to run?
First things first: “K” stands for kilometers, so a 5K is 5 kilometers long But if you live in the United States — one of the last three bases of the imperial measurement system — your brain has likely erased any information about the metric system by the time you finish middle school math, so it might be easier to consider how far a 5K mile is.
Let’s break down the distances of the 5K — and longer races like 10K, 15K, half marathon, marathon, and ultramarathon — to give you a clear idea of the distance each covers and how long it will take to cross the finish line.
How far is a 5K race?
A 5K is 3.1 miles long. To put that in perspective, that’s the equivalent of running 45 laps around a baseball diamond. At a 10-minute mile pace, it will take you about 31 minutes to run the 5K.
How far is a 10K race?
A 10K is 6.2 miles long. If you’re considering training for a 10K, that’s the equivalent of running the length of 91 football fields, including both end zones. At a 10-minute mile pace, you’ll finish the race in about an hour and two minutes.
How far is a 15K race?
A 15K is 9.3 miles long. That’s the equivalent of running the length of an NBA-regulation basketball court a little more than 522 times. At an 11-minute mile pace, it will take you about an hour and 43 minutes to run the 15K.
How far is a half marathon?
A half marathon is 13.1 miles long—less than 53 laps around a standard outdoor 400-meter track. At a 12-minute mile pace, it would take you about 2 hours and 37 minutes to run a half marathon.
How far is a marathon?
A marathon is 26.2 miles long. That’s about 105.5 times the length of a standard outdoor 400-meter track (and would be the last half of a lap the worst) at a 12-minute mile pace, it would take you about 5 hours and 15 minutes to run a marathon.
How far is an ultramarathon?
An ultramarathon is any race longer than a marathon. This can range from a 30-mile trail race to a 200-mile Ragnar Relay.
What is a good running speed?
There is no one-size-fits-all answer. A “good” running pace differs from runner to runner, and depends on factors such as your age, fitness level, terrain (eg, whether the race is flat or hilly), and distance (you may have noticed that mile times have increased in the example above). However, a running pace chart can help you understand what a good pace might be for you during your next run.
