Pay attention to these body indicators to know when to run and when to back off.

First, your sleep patterns and energy levels will feel the effects. Eventually, your immune system crashes, and you lose your appetite. It’s like burning out your engine. And you don’t have to be logging 100-mile weeks to suffer. Recreational runners can overtrain, too. “With deadlines, chores, bills, kids, and lack of sleep, it’s more challenging to recover properly from your runs,” says Sims.
Pay attention to the following 10 markers. If three or more of these indicators raise a red flag, you should consider a few easy sessions or off days so you can return to running strong.
You lost weight from yesterday
Your resting heart rate is elevated
Take your pulse each morning before you get out
of bed to find what’s normal for you. An elevated resting heart rate is
one sign of stress. It means your nervous system prepared for fight or
flight by releasing hormones that sped up your heart to move more oxygen
to the muscles and brain. Your body won’t know the difference between
physical and psychological stress. A hard run and a hard day at work
both require extra recovery.
You didn’t sleep well or enough
A pattern of consistently good sleep will give
you a boost of growth hormones, which are great for rebuilding muscle
fibers. Several nights in a row of bad sleep will decrease reaction time
along with immune, motor, and cognitive functions—not a good
combination for a workout.
Your pee is dark yellow
This can be an indicator of dehydration, barring
the consumption of vitamins, supplements, or certain foods the evening
before. The darker the color, the more you’re struggling to retain
fluids, because there’s not enough to go around. You need H2O to operate
(and recover).
You’re run down
If your energy level is low, there’s something
amiss. The key is honesty. Athletes can block out signs of fatigue to
push through it, thinking it will make them stronger. It won’t always
work that way.
You’re cranky
When your body is overwhelmed by training (or
other stressors), it produces hormones like cortisol that can cause
irritability or anxiety. Stress also halts chemicals like dopamine, a
neurotransmitter in the brain that has a big bummer effect on mood when
depleted. Crankiness probably means not enough recovery.
You’re sick
Any illness, or even a woman’s menstrual cycle,
will increase your need for energy to refuel your immune system, which
is having to work overtime. This means fewer resources available for
recovering from training.
You’re sore or nursing an injury
Whether you’re sore from overworked muscles or
an injury, your body needs more energy to put toward repair, lengthening
total recovery time.
9. Performance
Your workout went poorly
This is a subjective measure of workout quality,
not quantity nor intensity. If you felt great on yesterday’s run, you’d
evaluate that as good. If you felt sluggish on that same run, you’d
count it as poor. Trending workout quality—multiple poors in a row—is
one of the easiest ways to identify the need for more recovery.
10. Oxygen Saturation
Your oxygen level has dipped
The amount of oxygen in the hemoglobin of the
red blood cells can be measured by placing your fingertip in a portable
pulse oximeter, a gadget available online for about $40. The higher the
percentage, the better: Above 95 percent is the norm at sea level or for
an athlete who is fully acclimated to a given altitude. This is a new
area in recovery science, requiring more research, but there may be a
link between low oxygen saturation and the need for more recovery.
