Marathon Goals Explained: How to Setup Meaningful Realistic Goals

The #1 mistake runners can make when preparing for a marathon is setting up the wrong marathon goals, which usually ends in injury or disappointment. 

But don’t worry. At the end of this article, you will have a clear plan to set a meaningful, realistic goal that sets you up for success. We even have a handy calculator to help you.

Your marathon goal is the foundation of everything you will do over the following weeks:

  • How long is your training plan
  • Your long runs
  • Your rest days
  • How fast or slow you will run
  • Your fueling strategy
  • etc.

Setting a realistic yet challenging marathon goal is the first step to training smarter and maximizing the time you devote to it.

Marathon Goals Are Not Random

When setting a marathon goal, it’s essential to remember that this decision should not be made randomly or arbitrarily (as 90% of runners do).

Your marathon goal should be based on your current running fitness level or recent performances. Choosing a challenging and achievable goal is crucial, as this will provide the motivation and focus needed to succeed. 

Simply picking a random number, like under 3 or 4 hours, without considering your fitness level and past performance usually leads to a poor training plan that has two outcomes:

1. Your Marathon Goal is Way Beyond your Capabilities

You overtrain and get injured by pushing your body beyond its limits.

2. Your Marathon Goal is Way Below Your Capabilities

You are disappointed throughout your training and finish your marathon, knowing you could have gone faster. 

Instead, take the time to evaluate your current capabilities and set a goal that is both realistic and ambitious. By doing so, you’ll be able to train more effectively and increase your chances of achieving your target with success. Remember, marathon goals are not random – they require careful consideration and thoughtful planning.

Setting Marathon Goals Based on Your Current Fitness

If you’ve never run a marathon, haven’t run one in a while, or are returning from an injury, assessing your current running fitness is the best starting point.

I recommend doing Dr. Veronique Billat’s 6-minute test to asses your vVO2 max. Check out the video below, where I explain how to perform the test.

One really useful thing about this test is that you can perform it regularly. You can do it every 4-5 weeks to assess your fitness and adjust your training paces. This way, you are always training to your fullest potential.

Real Life Example

Three weeks before my fastest marathon to date —Mississauga 2022— I did a 6-minute test at a pace of 3:19/km, which predicts a 2:55:31 marathon. In the end, I was able to run that marathon with a personal record of 2:54:31.

Setting Marathon Goals on Recent Performance

I personally like, use, and recommend the 6-minute test to set a marathon goal. But many people also like to use a recent race to do it.

Just a word of warning. Your fitness could be very different if your recent race was more than 3-4 months before starting your marathon training.
