Coach Sage Canaday teaches you what it takes to run a sub 45-minute 10k!
A few weeks back, Coach Sage Canaday gave his advice on what to do in order to crack a sub 22-minute 5km. Now, he’ll take it one step further if you’re looking to run a fast 10k! These are tried-and-true training methods and workouts that can be adapted, whether you’re slightly faster or slower than these target times.
Let’s Start Off With The Math
To achieve a sub 45-minute 10K, you’ll need to maintain a pace of approximately 7:15 per mile or 4:30 per kilometer. Ideally, you should be able to run a 5K under 22 minutes—closer to 21:30 would be even better. If you haven’t yet reached that level, it will be challenging to sustain two back-to-back 22:30 5Ks, which is necessary for a sub 45-minute 10K.
Getting Started
So if you’re not quite there yet, focus on racing some 5Ks first to build up your speed and fitness. Once you’ve achieved a solid 5K time, you can then move up to the 10K distance and work on lowering your time there as well. The key is to develop your baseline speed for the 5K and then apply it to the 10K. About 80% of your baseline or “easy” pace should be about 8:45 per mile or 5:30 per km. If you’re in sub 45-minute 10km fitness, this is the easy pace that you’d be shooting for.
Since a 10K is twice as long as a 5K, it’s crucial to have extra endurance and stamina. But once you’ve built a strong mileage base and are consistent in your training, you can start incorporating quality workouts. These harder sessions include speed and interval workouts, similar to those in 5K training. For the 10K, it’s better to focus on longer repeats, such as mile repeats or 1600-meter intervals.
Advanced Workouts for 10K Training
To train effectively for a 10K, it’s crucial to include workouts that challenge both your speed and endurance.
Workout #1: Tempo Runs
Before starting the interval workouts, it’s beneficial to build up your stamina with tempo runs. Begin with a 20 to 25-minute tempo run at a pace slightly slower than your goal 10K pace, around 7:25 per mile or 4:35 per kilometer. This steady-state effort, at about 80 to 85% of your maximum, is controlled and sustainable, helping you develop the stamina needed for longer periods of sustained effort. Incorporate this workout once a week as part of your training routine to enhance your endurance and to get your legs and breathing accustomed to a near 10K pace.
Workout #2: Vo2 Max Workout
The next key workout is mile repeats. Aim for 4 to 5 repeats of 1 mile or 1600 meters each, targeting a pace of around 7:00 to 6:55 per mile. You can perform these on a track or a flat, measured path. Between each repeat, take a controlled rest break of 3 to 4 minutes. During this rest, you can walk or jog lightly, but your heart rate should not fully return to its resting state. This will keep you slightly fatigued, building specific strength and endurance for sustaining a high-effort pace over the 10K distance.
These intervals will elevate your heart rate to over 90% of your maximum and get your legs accustomed to running significantly faster than your 10K goal pace. This makes your goal pace feel more comfortable on race day!
Workout #3: 400-Meter Repeats
Similar to the 5K training, include 400-meter repeats at a pace faster than your 5K race pace. Aim for 8 to 10 repeats at 1:38-1:40 each on a track with a two-minute rest between each rep. This workout helps develop your top-end speed, which can be useful for a strong finishing kick in a 10K race. However, this is not as crucial for 10K training as it is for 5Ks. Consider doing this workout once every two weeks.
Workout #4: 2-Mile or 3200-Meter Repeats
The final key workout I’ll give you for today is 2-mile repeats or 3200-meter repeats. Perform these at your current 10K race pace, with the goal of gradually working down to your target 10K pace. For example, you might aim to complete each 2-mile repeat in around 14.5 minutes if targeting a sub-45-minute 10K. Try to do 3 sets of these repeats with a short, 5-minute rest in between. This workout covers approximately 6 miles of running at or near race pace, which is about the same distance as a 10K.
This type of workout is essential for building strength and stamina specific to 10K racing. It targets your 10K pace and is a staple for preparing your body to maintain that speed over the race distance. You only need to do this workout about once every two weeks.
The Five-Pace Theory
Think of your 10K pace as being in the middle of a five-pace spectrum. There are two paces slightly faster and two paces slightly slower than your 10K race pace. Training across this range ensures a balanced approach to developing both speed and endurance.
Let’s put it all together:
Structuring Your 10K Training Plan
In your training plan, it’s essential to include a variety of paces to maximize your 10K fitness. Here’s a quick breakdown of the key paces and workouts:
1. Easy Pace:Base mileage runs at a relaxed, conversational pace.
2. Tempo Runs:Sustained efforts at a slightly slower pace than your 10K goal pace.
3. 10K Pace: Longer intervals like 2-mile repeats performed at your current or goal 10K race pace.
4. 1-Mile Repeats (1600 meters): Faster intervals to build speed endurance.
5. 400-Meter Repeats and Strides: Shorter, high-speed intervals to develop top-end speed and running economy.
Mixing these workouts in a cohesive plan is crucial for achieving your best 10K performance. Proper timing and progression of these workouts are important, so be sure to build your base mileage first before adding in the harder sessions.
I hope this is helpful – happy running and have a great week!
