Run Your Fastest 10K in 8 Weeks
Crush 10 kilometres in 8 weeks with training and race day tips from the pros
The 10K falls squarely between the two most popular race distances: the 5K and the half marathon. Yet, only 1.5 million runners registered for 10km races, compared to nearly nine million for the 5km in 2019, according to Running USA’s U.S. Running Trends 2020 report. Where’s the love for the 10K?
For athletes like Dominique Scott, a professional runner who represented South Africa in the 10,000-metre race (the track equivalent to a 10K road race) at the 2016 Summer Olympics and the 2020 Summer Olympics and trains with Team Boss in Boulder, Colorado, it’s the length that’s so appealing. “So much can happen and change during those 10 kilometres,” says Scott. “It’s long enough that there’s time to warm up into it—which I like—but also long enough that you need to have a strong mental game.”
That perspective applies to recreational runners as well as the pros. “Regardless of how long this distance takes you to complete—whether it’s a half hour or a over an hour—it’s similar to a tempo or threshold run,” says Marco Anzures, a USATF-certified endurance coach, certified strength and conditioning specialist, and head women’s cross-country coach at San Diego City College. “It’s a nice, hard distance, but it’s not as intimidating as a 5K [in terms of speed] and it’s not going to beat you up the same way a half marathon might.”
With a solid aerobic base, you can be ready to race a 10K in as little to six weeks (and no more than 12 weeks), says Anzures—a way more accessible timeline than a lengthy half marathon or marathon training plan.
How to Prepare for Racing a 10K
Clock your fastest times at this distance by prioritising two types of workouts: long, steady state runs and speed work, says Anzures.
“Long runs should be done at half marathon or marathon pace,” he says, where your effort level is between 50 to 85 percent of your max heart rate, or a 6 to 7.5 on a scale of 1 to 10. These slower efforts strengthen your slow twitch (type I) muscle fibres, which are geared towards endurance events, and train your cardio, respiratory, and muscular systems to work more efficiently—which will help you go faster in the long run.
For lower volume runners, you want to at least cover the race distance, a.k.a. 10 kilometres or 60 minutes, in your long run training, says Anzures. “Closer to the race, you can incorporate faster paces in the second half of those long runs, closer to what you think your race pace intensity might be. Runners who are used to higher mileage wouldn’t want to go longer than 30 kilometres or two hours,” he says, referring to your max distance long run. And you don’t want to do that super long run every week. “Every other week is enough to maintain your aerobic system,” he explains.
A 10K race is a mostly aerobic effort, meaning your hearts and lungs are able to keep up with the oxygen demands of your muscles. “Don’t neglect the long run!” says Scott. “Whether you’re doing a hard long run or just spending time on your feet, the long run is very important to increase your aerobic ability.”
To strengthen your running economy, or your ability to run faster while using less energy, you’ll have to pick up the pace.
“Runners aiming to finish in around an hour should do speed work that taps into your kilometre pace for shorter reps of 100 to 400 metres,” says Anzures. (Do those repetitions on hills to up the intensity and help you get more power from every step.
“For those who can cover 10K in 40 minutes or less, you want to do longer chunks—maybe 1K or 2K intervals throughout four or five kilometres of work —at threshold effort,” says Anzures. That means going slightly slower than your 5K pace.
For example, every other week in the months leading up to the Tokyo Olympics, Scott ran 6km at 3:18 pace followed by four 400-metre intervals, getting faster with each repetition. “This is a great race simulation workout as racing 10,000 metres feels pretty similar,” she explains. “You’re in a happy rhythm for the majority of the race, and then try to increase your turnover with three kilometres to go when you’re already tired.”
How to Have a Successful 10K Race Day
No race day exists in a vacuum, so setting yourself up for a PR begins way before you get to the start line. “Make sure you’re hydrating well in the days leading up to the race—the day of is too late,” says Scott. “Then eat a light meal two or three hours before the start of your race. I like to have a peanut butter and banana sandwich three hours before and two shots of espresso 90 minutes before my races.”
Once you do cross the start line, stay patient. “That first kilometre, err on the side of being a little slower, because you can always pick it up based on how you feel,” says Anzures. “It’s a lot harder to pick up the pace at the end if you go out way too hard in a 10K because you still have so much ground to cover.”
During the race, as Scott said earlier, you’re going to have to tap into your mental strength. “10 kilometres is a long time to focus and stay engaged,” she says. “I personally try to break the race up into two 5Ks: The first 5K I find my pace and ‘my people’ and then try to stay as relaxed as possible. I focus on having a calm mind, keeping my body relaxed, and not thinking about too much else. The second 5K is when I tell myself it’s ‘race time’ and shift my focus to racing the people around me and being aware of what my splits are.”
Your 8-Week 10K Training Plan for a Faster Finish Time
Ready to cover 10 kilometres faster than ever? “This 10K training plan will work well for a runner who has several months of running under their belt already and can run around 30 kilometres a week,” says Anzures. “In the first four weeks, the workouts emphasise sharpening aerobic power. Then you’ll transition into specific aerobic development for the 10K during the last four weeks.”
If you’re not up for two workouts per week, you can swap out Friday’s session for an easy run—don’t skip the Tuesday workouts or the weekly long run, though. Make sure to perform an inclusive warmup with a jog, dynamic drills, and strides prior to each workout. And don’t forget postrun recovery, too.
