First, name the kind of tired
If you are a little sluggish but otherwise okay, an easy run may help you loosen up. If you are underslept, unusually sore, mentally drained, or carrying several hard days in a row, the workout may need to change.
RaceIQ is built around this reality: the same planned run can be right on one day and wrong on another.
Do not judge today's run in isolation. Look at the last 48 hours, the next key session, and the stress already in your legs.
Easy effort is often the bridge
When fatigue is moderate, shifting a hard workout to an easy run can preserve consistency without adding the wrong kind of stress. You still get movement, rhythm, and habit without pretending your body is fresh.
RaceIQ helps you decide whether to move, modify, or protect the next workout.

One tired day is normal. Several tired days plus bad sleep, hard cross-training, heat, and a looming long run is a different story. Plans should adapt when stress stacks up.
These guides come from the same belief behind why RaceIQ was built: rigid plans do not work for runners with real lives.
The plan should adapt when the week changes.
RaceIQ helps runners adjust the day's training when fatigue changes what makes sense.
