Upon signing up for your marathon, the excitement of committing to 26.2 miles quickly turns into a series of questions: How am I going to train for this? How much time can I dedicate? Which plan suits my fitness? What goal do I want to achieve?

These are the same questions millions of runners ask themselves after hitting "register." Fortunately, in the age of wearable technology, training smarter has never been easier. With data-driven insights tracking your fitness, why not build a customized plan in under a minute?

Thanks to the COROS personalized plan, I trained with more discipline, ... and felt more confident than I ever had.

How The COROS Personalized Marathon Training Plan Works

By leveraging decades of historical sports science research, the Personalized Marathon Training Plan ensures that you build strength in the key areas that drive race-day success.

Along with proven research, the plan also considers your own personal training history. Regardless if you have used a COROS for five years or just five days, the COROS ecosystem learns who you are as a runner and identifies your strengths and areas for improvement.

With COROS handling these key insights, all you need to do is input how many days per week you can train and your goal finishing time. If you have a race date planned, you have the option to input that as well. From there, the rest is taken care of.

You will receive an 8-16 week plan (based on your preference) to help achieve your goal in the most efficient way. Your COROS watch will also guide you through each workout step by step, so you never miss a beat.

The COROS Personalized Marathon Training Plan is for athletes with a current marathon time of 3:30 or above. For Athletes running faster, we have advanced training plans available on our site that can be downloaded for guidance as needed.

How To Start

To get started with your COROS Personalized Marathon Plan, open the COROS app, select the Personalized Marathon Plan widget from the progress page, or navigate to your training calendar and select the settings menu to access it. From there, follow the steps to generate a plan tailored to your fitness level and race goals. Watch the video below for a step-by-step guide!

Changes Based On Fitness Improvements

As you take on your marathon training journey, your fitness is likely to improve. When these improvements happen, your COROS automatically tracks these changes and updates your pace and heart rate zones. Therefore, when the training plan calls for "Zone 2" running, your zones are updated to ensure you're always training as at the right intensity for your current fitness.

Athletes are likely to see changes in their pace zones, heart rate zones, running fitness, and race predictor. These can be great for confidence as you inch closer to your ultimate goal.

Proven Results

The COROS Personalized Marathon Training Plan was launched in November of 2023. Since the launch, COROS has led two 500-person training camps leveraging this technology.

Following the training camps, 257 attendees noted a personal best, with a clear majority noting they had an enjoyable experience in not only their training, but also race day performance.
