Following a 25k training plan can be very helpful for runners of all ability levels. A 25k race is an unusual distance, making it difficult to follow a typical half marathon training plan. This 15.5 mile running distance is just enough to test the limits of half marathon fitness without pushing too far.
How far is a 25k?
25 kilometers is about 15 ½ miles, or specifically, 15.5343 miles. The distance is about two miles longer than a half marathon and nearly 11 miles shorter than a full marathon. 25k races are popular among runners who have completed a half marathon and are looking for a further challenge.
How long should you train for a 25k?
Training time for a 25k varies from one runner to the next, depending on experience level and personal goals. Experienced runners who have already completed a half marathon may be able to train for a 25k in just a few weeks, while new runners may require multiple months.
When deciding on the length of a 25k training plan, it’s important to account for your current base mileage. Runners who have recently completed a half marathon can simply add 1 or 2 long runs and be ready for the distance. Runners starting with a base of 3 – 5 miles should plan for at least 12 weeks of training.
Who can use the 25k training plan?
This 25k training plan is useful for runners of all ability levels, from beginner to advanced. The plan is written for beginner to intermediate runners, or those with a base of at least 5 miles. Advanced runners can modify the plan if needed by starting at week 3 or 5.
The 25k training program is ideal for runners who want to build their running base and prepare for the 15 mile distance without running every day. With just three runs each week, this training plan can be completed even in the busiest of seasons. However, with speedwork and increasing long runs, runners will still be adequately prepared at the starting line.
25k Training Plan Structure
The breakdown of this 25k Training Plan is as follows:
- Monday – cross training
- Tuesday – speed workout (400 meter repeats or tempo run)
- Wednesday – strength training
- Thursday – easy run
- Friday – yoga/active recovery (optional rest day)
- Saturday – long run
- Sunday – rest
25k Training Plan Workouts
The mileage in this training plan gradually increases over the course of 14 weeks, with a few cutback weeks to recover. Long run mileage begins with 5 miles and increases to peak at 14 miles, in addition to one easy run and one speed workout each week.
Speed workout – this 25k training plan features a weekly speed workout that alternates between interval and tempo runs. If these workouts are being completed on a track, consider investing in workout shoes specifically for this weekly run to really enhance your performance.
Interval workouts are written as “# x 400”, which indicates the quantity of 400 meter repeats to be completed. Each 400 meter interval should be followed by a 200 – 400 meter recovery period of either jogging or walking. These intervals should be completed as fast as possible.
Tempo runs should be completed at a comfortably hard pace, one that can be sustained for the duration of the run. Complete a 5 – 10 minute warm up and cool down in addition to the designated tempo portion of the run.
Long run – this is the most important workout in the entire 25k Training Plan. Each weekly long run serves to build endurance and create the necessary training base to conquer a 15.5 mile race distance. Beginning with 5 miles, the weekly long run slowly increases distance each week to help runners build endurance without overtraining or injury.
Active recovery – this refers to activities that are relatively low impact, such as walking, yoga, swimming, etc.
Strength training – refers to either bodyweight or weighted exercises that help strengthen muscles throughout the entire body. When time is limited, focus on leg strength, but whenever possible, incorporate full body exercises. This Strength Training for Runners Workout is a great at home option.
Cross training – any form of exercise other than running. Swimming, biking, walking, sports, weight lifting, hiking, yoga, pilates, etc. Cross training workouts are typically more active than strength training and require similar cardiovascular effort as running.

25k Training Plan Tips
Training for a 25k requires time, patience and incredible commitment. The race distance is no easy feat, and certainly cannot be accomplished overnight. These tips will help runners prepare for the training season ahead and remain injury free, all while building the confidence and endurance necessary to conquer 25k.
Focus on quality over quantity
When training for a 25k, runners don’t necessarily need to add in a bunch of extra workouts – rather, they need to increase the quality of their workouts. Fitting in a short, focused speed workout each week is often much more effective than squeezing in three extra easy runs.
Taking the time to fuel, warm up, recover and hydrate during a long run will help build endurance without leading to injury or overtraining. While the training load might not look like a lot in this 3-runs-per-week plan, each run serves a distinct purpose.
Invest in the right gear
Completing and training for a 25k race requires many miles, workouts and intentional recovery sessions. While running certainly doesn’t require as much specialized equipment as other sports, it is still important to be intentional about the gear and clothing you do use.
Running in the wrong shoes can lead to a host of injuries, performance issues and nagging pain. The wrong clothes can quickly result in chafing, running or general discomfort. Taking the time to find high-quality workout clothes will not only help you train comfortably, but feel motivated and confident during each workout.
Many 25k runs are trail races, meaning that runners will need to invest in specialty trail running shoes. Trail races require significantly different footwear than road races, and attempting to train on the trails without proper shoes will quickly result in injury.
Prioritize long runs
Regardless of the intention and commitment runners have to their training plan, life gets busy and there will often come a time where workouts need to be skipped or modified. In these cases, its important to prioritize the long runs.
Whenever possible, the long run should be completed in its entirety. When faced with a time crunch, swap workouts around to ensure the long run can still happen, even if it’s on a different day. Skipping an easy run or cross training workout is okay once and a while if needed, but always do what you can to maintain the long run.
Incorporate weights
While running is certainly the main component of the 25k training plan, cross training plays a key role in avoiding injury and building strength. Incorporating weights into your weekly strength and/or cross training workouts will help boost power and mobility on the run.
Building muscle not only leads to potential performance gains, but it can help prevent injuries and avoid common overtraining pitfalls as well.
Fuel your body
Running long distances burns pretty significant calories, and they shouldn’t be replaced with just anything. It’s important to pay attention to the quality of foods you’re using for fuel before, during and after a run.
Practice fueling mid-run throughout training, adjusting the timing and type of fuel until you find something that works for your stomach on the run. Once you come up with a strategy, stick with it and practice during each long run.
Stay consistent
Consistency is one of the biggest factors of success with this 25k training plan. Showing up each day, completing the workouts to the best of your ability, filtering out excuses and listening to your body will lead to optimal race day success.
