How To Train For A 5K, According To A (Very Fast) Professional Distance Runner
Liv Paxton is a lifelong runner and 4x marathoner with a personal best time of 2:56:28 set at the 2023 Chicago Marathon. Liv has worked in running for six years and has done everything from selling shoes to coaching beginner runners. If she is not out on a run you can find her watching re-runs of Gilmore Girls, drinking overpriced coffee, and reading a Colleen Hoover novel.
A 5K is a 3.12 mile race, and it's one of the most popular distances around the world for hobby joggers and elite athletes alike. Unlike a half marathon or full marathon, the 5K leaves you feeling tired, but able to actually walk afterwards — and with the same sense of accomplishment. Some seasoned runners may look down on the 5K, but I'm here to tell you that it's no small feat. In fact, in my 14 years of competitive running, the 5K was my main focus for 12 years.
If you're looking to run your first 5K and have no background in cardio or endurance sports, a simple google search for “beginner 5k workouts” will lead you to dozens of workout plans. While I have coached true beginners, my coaching specialty is with more intermedia runners, or runners trying to run their fastest 5K. You don't have to be a standout athlete or elite runner to set goals, and there are some simple steps everyone can take to get faster. Heres how to train for a 5K race, the Paxton way.

The first step to bettering your 5K is to pick a race and sign up for it — most cities have a few 5K to choose from each weekend, so there should be plenty to choose from. Having a race on the calendar ensures you won’t skip out on your training. I recommend giving yourself 8-10 weeks to properly train.
The best 5K training plans, in my opinion, include 4-5 days of running a week. Every week should include:
- One or two speed workouts
- A few easy jogs
- A long run
You should never run hard or fast two days in a row — easy jogging and rest between speed workouts are both essential for rebuilding muscles damaged with hard workouts. Here's how each of the three main training workouts should go.

Speed Workouts
Every speed workout should begin with a 5-10 minute jogging warm up and a 5-10 minute jog/walk cooldown. This will help ensure you do not pull or strain any muscles.
The actual "speed" part of speed workouts can go one of two ways:
- Run 2-3 minutes at a harder 7 out of 10 effort, with a standing or walking rest of 2-3 minutes between each push.
- Run 6-8 repeats of a steep hill for 45-60 seconds in length with a walk back down, before repeating again.
Easy Jogs
Easy jogs should be kept at a conversational pace, so this would be a good time to grab your girlfriend or hop on the phone if you want some company. The best jogs should be about 2-3 miles in length, or 20-35 minutes in duration.

Long Runs
Long runs are arguably the most important workout of the week, and anyone trying to better their 5K time should make sure to include them in their training plan. Like the name suggests, a long run should be your longest run of the week. Your longest run can be anywhere from three miles at the beginning of the plan to 12 miles if you're an experienced and seasoned vet. I recommend starting with 3 miles at the beginning of your 8-10 week plan and working your way up to 5-8 miles by the end. You should do this by adding one half to a full mile each week. Although it may sound silly to run 8 miles in order to run a 3.1 mile race, this will help build your endurance more than any of your other weekly runs. Having endurance will make the race seem easier, and I can guarantee you'll pass people left and right in your final mile.
Note: You should also have at least 10 days between your longest long run and your 5k race so that you can feel as fresh as possible on race day.

The most important thing to remember on race day is to not go out too fast. If you sprint the first mile, the rest of the race will be miserable. Race day adrenaline will make you jittery and willing to sprint at the start, but working on controlling that will ensure a better race experience. Try to make your second and third mile faster than your first and give it all in the last .1 mile. After you’re done, soak in the race day atmosphere and grab a free banana! Don’t forget that the post race pain is temporary and remember not to sign up for another race while on an endorphin high!
