# 21km In Miles

21km In Miles – Setting race distances for both new runners and experienced runners looking for a new challenge, your mind is constantly trying to make the conversion between miles and kilometers. Although the US still clings to the mile, and perhaps forever will, many races are actually measured in kilometers, part of the widely accepted metric standard.

Although this is a rare race distance, I happened to find a track race within an hour of where I live. The trail race is called Big Mammoth and you run around the world famous Glenrose State Park in Texas (known as Dinosaur Valley State Park). When you drive here, don’t forget to take a break afterwards and check out the dinosaur tracks in the river water.

A half marathon is equal to 21.1 kilometers. Although technically the race is 21.1km, most people just drop 0.1 and make it 21K.

A marathon is equal to 42.2 kilometers. Although technically the race is 42.2km, most people just drop 0.1 and make it 42K.

The 100 kilometer running of an ultramarathon is equal to 161 kilometers. How many meters is the distance of the standard railway in the United States?

Clients ask me all the time, “How do I start running?” My answer: “Do you want a long/safe answer or a short/quick answer?” I would get all kinds of answers:

## Your Marathon Mindset 13.1 Miles

First and foremost, the short/quick answer is for people who meet these criteria: fit, healthy, free of medical conditions and physically able to walk. Are you ready for the answer, “Just start running!” That’s all! Most customers then respond with something like, “How far, how long, how many times…” and the short answer becomes a long answer with no intention of luring them with a long and ultimately unsexy answer – “it depends”. As most new runners are usually not 100% fit (usually the reason most of us start running is to get in shape), it is inevitable that they will need a bit of guidance/advice to get them into to go in the right direction.

First, although I’m saying this for the 111th time (not sure how many times I’ve said it), you need to get a physical from a licensed doctor (which I am not) before you start running. Also, when you do your physical, tell them what you want to do, like run a 5K, run a half marathon, start a running routine. Depending on what you want to do, they may do additional tests to make sure you can physically do it without injuring yourself or worse.

It doesn’t matter if I tell the client to do the physical or someone else does. The truth is, most people don’t consult their doctor before starting a new exercise routine, especially running. Running is a constant impact sport that works your leg muscles so far, have you seen the legs of soccer players and runners – they look really good! Their legs look toned and fit because they are constantly working on those muscles.

While the answer to your question may seem brief with the links posted below, some are deep dives into the subject. You should be able to create your own running routines and/or follow some of the training plans I created to get you to your goal using the links below. Even if you are a walker, not a runner. For new runners, read these posts in the following order:

## What Is A Good Half Marathon Time?

Points 1-5 focus on proper technique, how long, how far, and run-walk strategies to facilitate running. Item number 6 is a truly completely free plan that implements a run/walk strategy to achieve your first baby goal as a runner – run 1 mile without stopping.

Once you can complete a mile, you are ready to move on to the next level of running, which is the 5K. I have many more posts aimed at new runners, including training plans for a 5k, 10k, half marathon and soon a marathon.

Some of you may already be ready to run a 5K, so you can skip a 1-mile workout. It all depends on your physical condition. You can get most of my freebies here:
