# How Many Miles is a 5K, 10K, Half Marathon, Marathon, Ultra Marathon?

Determining race distances for new runners as well as experienced runners wanting a new challenge your mind is constantly trying to convert between the mile and the kilometer. While the U.S.A. still clings to the mile, and will possibly forever, a lot of the races are actually measured in kilometers which is part of the widely accepted metric standard.

## Where should you start when attempting a new running habit/routine?

Clients ask me all the time, “How do I get started running?” My reply, “well do you want the long/safe answer or the short/quick answer?” I would get all kind of responses:

• “Running is dangerous?”
• “I don’t have much time, I’ll take the short/quick answer.”
• “I would rather be safe, let’s take the long/safe approach.”

### How do get started running (short/quick answer)

First, and foremost, the short/quick answer is for individuals that fit this criterion: in-shape, healthy, no underlying medical conditions, and physically able to run. Are you ready for the answer, “Just start running!” That’s it! Most clients then respond with something like, “So how far, how long, how many times…” and the short answer becomes the long answer with no intentions of tricking them into the long and ultimately non-sexy answer – “it depends.” Since most new runners, are normally not 100% in shape (usually the reason why most of us start running is to get in shape), it’s inevitable that they need a little coaching/advice to get going in the right direction.

### How do get started running (long/safe answer)

Firstly, even though I’ll say this for the 111th time (not sure how many times I’ve said it), before you start running you should get a physical wellness check with a medically licensed physician (which I am not). Also, when you get a physical exam, tell them what you’re wanting to do such as, run a 5K, run a half marathon, start a running routine. Based on what you want to do they might run additional tests to make sure you can do this, physically without injuring yourself or worse.

It doesn’t matter If I tell a client to get a physical exam or someone else does. The truth is most people don’t check with their doctor before starting a new exercise habit, especially running. Running is a continuous impact sport that works your leg muscles to no end, have you seen the legs on soccer players and runners – they look really good!  Their legs look toned and in shape, because, they are continuously working those muscles.

While the answer to your question might seem short with the links I post below, some of them are deep dives into the subject. With these links below you should be able to create you’re own running regimes and/or follow one of my training plans that I created to get you to your goal. Even if you’re a walker and not a runner.

### For absolute new runners – read these posts in the following order:

Items 1-5 focus on proper technique, how long, how far, and run-walk strategies to ease you into running. Item number 6 is an actual complete free plan that implements a run/walk strategy in getting to your first baby step goal as a runner – running 1 mile without stopping.

After you’re able to tackle the mile you’ll be ready to continue to the next level of running which is the 5K. I have many more posts that focus on new runners including 5k, 10k, half marathon, and soon marathon training plans.

Some of you might already be ready to run the 5K so you can skip the 1-mile training. This all depends on your physical fitness level. You can grab most of my free plans here:
