What I Do When I Miss a Run (and Why I Don’t Make It Up)

Missing a run used to stress me out more than any workout. During training for my first and second marathon, skipping even one session felt like a failure. I’d replay it in my head, worry about lost fitness, and start looking for ways to “fix” it. That stress usually did more damage than the missed run itself.

Back then, one skipped session often spiraled into rushed make-ups, stacked mileage, or forcing workouts on tired legs. Over time, I realized the missed run wasn’t the real problem, how I reacted to it was.

When you’re training for a marathon around work and real life, missed runs are inevitable. Long days, poor sleep, unexpected obligations, they happen. The mistake is treating a missed run like a debt that needs to be repaid immediately.

I don’t make up missed runs anymore. Not because they don’t matter, but because forcing them almost always costs more than they give back. Adding mileage on fatigued legs or compressing hard days usually turns one missed session into several compromised ones.

This matters even more if you’re following a higher-volume training program. When your mileage is spread across the week, missing one run doesn’t suddenly erase your fitness. The volume itself creates a buffer. One skipped session is noise, not failure, unless you turn it into a bigger problem by forcing a make-up run your body isn’t ready for.

Now, the first thing I look at is what kind of run I missed. If it was an easy run, I let it go completely. Easy mileage is about consistency over time, not perfection in a single week. Trying to squeeze it in later usually just adds fatigue without meaningful benefit.

If I miss a workout, I zoom out before reacting. One missed workout doesn’t define a training block. During my earlier marathons, I treated workouts like checkpoints I couldn’t afford to miss. Now, if I’m otherwise consistent, I continue with the plan as written. Occasionally I’ll slightly adjust effort in the next quality session, but I don’t double workouts or chase volume. The goal is to protect rhythm, not prove discipline.

Missing a long run gets more attention, but still not panic. If it’s early in a block, I move on. If it’s closer to race day, I’ll sometimes adjust the following week, shortening recovery runs or slightly extending the next long effort, but only if my legs are ready. If they aren’t, I accept the tradeoff and prioritize recovery.

One of the biggest lessons I learned between my early marathons and now is that training plans assume perfect conditions. Real life doesn’t. The runners who stay healthy and improve aren’t the ones who never miss runs, they’re the ones who absorb disruptions without compounding them.

Now, when I miss a run, I ask one simple question:
What decision helps me train well next week?

Most of the time, the answer is restraint.

Consistency isn’t about never missing sessions. It’s about not letting one missed run turn into a cascade of bad decisions. Let it go. Protect the week. Keep moving forward.
