WHAT ARE THE SIGNS OF OVERTRAINING?

By Anthony WalshRoadman CyclingUpdated 31 August 2026

ANSWER

Back off when fatigue becomes a pattern: repeatable cycling performance falls, usual power feels unusually hard, tiredness does not improve as expected, or sleep, mood, motivation or health change together. No fixed resting-heart-rate, HRV, duration or symptom-count threshold diagnoses overtraining. Persistent or disproportionate fatigue needs clinical assessment because overtraining syndrome is a diagnosis of exclusion and overlaps with illness, iron deficiency, low energy availability, sleep and mental-health conditions.

KEY TAKEAWAYS

Look for repeated changes in performance, perceived effort, recovery, sleep, mood, motivation and health.
Resting heart rate and HRV can add context, but neither has a universal diagnostic cutoff.
One poor session is not overtraining; the pattern, duration and departure from the rider's normal matter.
Persistent or disproportionate fatigue needs assessment because other health conditions can look like under-recovery.

WHO THIS IS FOR

IS THIS YOU?

The rider who has been training hard for months without a break

You have stacked week after week of solid training and performance has gone flat or backwards.

The athlete confusing fatigue with underperformance

You feel tired but are not sure whether to rest or push through — understanding the distinction changes everything.

THE ROADMAN VIEW

Laurens ten Dam was on the podcast and he talked about this from the other side — the pro who overtrained himself into career crisis and had to find gravel racing to rediscover his relationship with the bike. The story is extreme, but the pattern behind it is not. Overtraining syndrome is what happens when you ignore the early warning signals for months.

Early signs can look like ordinary training fatigue: tired legs, flat power or a hard-feeling session. There is no day or watt threshold that separates normal fatigue, overreaching and overtraining syndrome prospectively. A repeated multi-system change that does not improve as expected deserves a lower training cost and, when persistent or disproportionate, clinical assessment.

Anthony's position is direct: the riders who recover fastest from overtraining are the ones who catch it early and act quickly. A week off when you are overtrained is far less costly than two months off when it becomes full syndrome. Listen to the numbers, listen to your mood, and resist the voice that says you just need to push harder.

EXPERT EVIDENCE

WHAT THE EXPERTS SAY

Laurens ten Dam16-year World Tour professional, Tour de France top-10 finisher
His own experience of overtraining showed that the mental signals — lost motivation, dreading training, inability to find pleasure in riding — arrived before the physical collapse. By the time power numbers fell significantly, the hole was already deep.

Dan LorangHead of Performance, Lidl-Trek
Overtraining syndrome is a medical diagnosis, not just a bad week. The path there is almost always the same: progressive under-recovery accumulated over months, often accompanied by under-fuelling. Prevention through planned recovery weeks is far more effective than managing the syndrome once it appears.

PRACTICAL APPLICATION

DO THIS WEEK

Track a consistent personal pattern
Measure resting rate with one repeatable method and record symptoms, wellbeing, sleep, recent load and comparable performance. There is no universal calibration period or 5-bpm rule; use agreement across observations to justify a cheaper session or further investigation.
Monitor mood and motivation honestly
Use the same simple scale and note meaningful changes rather than chasing a population cutoff. Athlete-monitoring reviews show subjective wellbeing often responds consistently to load, but it still cannot diagnose a syndrome by itself.
Reduce the cost of training while you reassess
Remove the next hard stimulus, restore adequate fuelling and regular sleep, reduce non-essential load and review the response. The amount and duration should follow severity, cause and response rather than one mandatory percentage.

COMMON MISTAKES

WHAT CYCLISTS GET WRONG

MISTAKEPushing through early warning signs because the event is close.
FIXTraining harder through overtraining signals makes them worse and pushes the recovery timeline further out. One recovery week now beats six weeks of forced rest later.
MISTAKEAssuming flat power is a training problem rather than a recovery problem.
FIXWhen power stalls or drops, check recovery first — sleep, HRV, resting heart rate, mood. Most apparent training failures are recovery failures.
MISTAKEUsing caffeine, motivation, and willpower to override the signals.
FIXThese tools mask the markers without addressing the cause. Perceived effort goes up, performance drops, and the recovery hole deepens.

FAQ

FREQUENTLY ASKED QUESTIONS

What is the difference between overreaching and overtraining?

Functional overreaching is a short-term performance reduction followed by recovery and possible improvement. Non-functional overreaching lasts longer without benefit, while overtraining syndrome is prolonged maladaptation and a diagnosis of exclusion. The boundary is judged retrospectively from the course and other causes, not from a simple day count.

How long does it take to recover from overtraining?

There is no universal recovery calendar. Duration depends on the state, the underlying contributors and the individual response. Suspected overtraining syndrome warrants appropriate clinical assessment and a progressive return rather than an internet timetable.

Can HRV detect overtraining early?

No. HRV findings in overreached endurance athletes are inconsistent and depend on the metric and method. A consistently measured pattern can add context beside performance, perceived effort, sleep, mood, illness and load, but it cannot diagnose or reliably predict overtraining by itself.

Does overtraining cause weight loss?

It can. Elevated cortisol from chronic under-recovery suppresses appetite and can cause unintended weight loss, which in turn often worsens under-fuelling and deepens the recovery deficit. Unexplained weight loss during a training block is worth taking seriously.

Is overtraining more common in masters cyclists?

Age changes health and recovery context, but masters status alone does not prescribe one training tolerance or recovery window. Compare the individual rider's response and include medication, cardiovascular history, sleep, fuelling and life stress.

Should I see a doctor if I suspect overtraining?

Yes, if symptoms have persisted for more than three to four weeks despite rest. A blood panel can rule out underlying issues (low iron, thyroid problems, low testosterone in males) that mimic or worsen overtraining. Medical oversight is important for recovery from full overtraining syndrome.
