Now that you’ve started to build a running foundation, you might be thinking about how to change things up. Maybe you want to take on new challenges or simply keep things interesting while staying injury-free and enjoying your runs.

Before you dive into the next phase of your running journey, keep this in mind: don’t change too many things at once.  Your body needs time to adapt to new stresses. Making small, intentional changes will help you continue to improve safely.

Here are some elements of running that you might be considering adjusting:

• Frequency – How many days per week you run
• Intensity – How hard you run (e.g., increasing your pace, adding speed work, or running hills)
• Duration – How long you run
• Surface/Environment – The terrain or conditions (e.g., treadmill vs. trails, hot vs. cold weather)

Even if you don’t intend to change anything about your running, factors such as weather, travel taking you to new running environments, life getting in the way of your running schedule, may force a change so here are some guidelines to help you adapt safely.

1. Change One Thing at a Time

Trying to adjust too many variables at once is one of the most common mistakes runners make. You might be tempted to increase your weekly mileage and add speed workouts in the same week—but that’s a fast track to injury.

Instead, focus on changing one variable at a time.

For example, if most of your runs have been on the treadmill and you want to start running outside more often, begin by gradually moving your runs outdoors without changing your distance, pace, or intensity.

Running outside is more challenging—you’re propelling yourself forward rather than relying on a moving belt, and you’re dealing with factors like wind and temperature. You might find your pace is a little slower outdoors, and that’s totally normal.

2. Build a Strong Base Before Adding Intensity

Speed can make your running more exciting, but it is also more stressful for your body. Before you add it in, make sure you’ve built up a consistent base of running.  What that base looks like will vary between runners. A good rule of thumb is to ensure you can run continuously for 45 minutes to an hour (at least one day a week) and have a regular routine of running at least 3 days per week.  We need to have consistency before we can add intensity.

Rushing into speed training too soon can increase your risk of injury. A strong base helps your body handle higher intensity safely.  So consider working on duration and frequency first before you start playing with intensity.

3. Make Small Changes

Whatever you change, make sure you make that change a small one.  For example, if you’re increasing your run duration, avoid big leaps from week to week. A general rule is to increase your total weekly running by no more than 10%.

Let’s say you’re running 30 minutes, three times a week—that’s 90 minutes total. Next week, you could aim to add about 9 more minutes. How you spread those extra minutes across your runs will depend on your goals.

4. Embrace Easy Runs

Don’t underestimate the value of easy runs. These should feel like a 5–6 out of 10 effort—where you can hold a conversation comfortably.

It’s tempting to chase faster times by pushing hard every run, but that often leads to burnout or injury. Ironically, running fast all the time can actually slow down your progress.

Running at an easy pace strengthens your cardiovascular system, conditions your ligaments and tendons, and helps your body recover between harder runs. The 80/20 rule: run about 80% of the time at an easy pace and 20% at a higher intensity is a good guideline to follow.  Assuming of course your body is ready for increased intensity!

5. Prioritize Recovery

Remember: you don’t get stronger during your runs—you get stronger after your runs, when your body adapts to the stress you’ve placed on it.

If you’re constantly pushing without giving yourself enough recovery time, you’ll start to feel run down, your performance may decline and you may end up with an injury. Recovery is where the real magic happens.

Quality rest goes beyond just taking days off. Here are four major factors that affect how well you recover:

• Sleep – Your body does most of its healing at night. Without enough quality sleep, you won’t recover properly.
• Nutrition – If you’re not giving your body enough fuel (especially carbs, protein, and healthy fats), your recovery will suffer.
• Exercise Load – If you’re also doing other forms of exercise, that will add physical stress to your body.  While light exercise like walking can help you recover, more intense forms of exercise will create an even greater need for rest.
• Life Stress – Don’t overlook the impact of mental or emotional stress. Work pressure, relationship issues, grief, family stress can all take a physical toll. If your recovery feels off, take stock of what’s happening in your life—it might be time to back off the running a bit until the life stress is more manageable.

6. Listen to Your Body

Any change you make creates new demands. Pay attention to how your body responds.

A run that feels like a 5/10 effort on pavement might feel like a 7/10 on trails, snow, or in strong wind. You might need to slow down to maintain the same level of effort, and that’s okay.

Instead of chasing a certain pace or distance, consider focusing on time and effort. This approach helps prevent overtraining and keeps your running sustainable and fun.

Progressing your running can be one of the most rewarding parts of your journey. Whether your goal is to run farther, get faster, or race competitively, the key is to make thoughtful, gradual changes—and to pay close attention to how your body responds.There’s no rush. You’ve already made amazing progress, and the best part is still ahead. Be patient, be kind to yourself, and most of all—enjoy the run.
