"I keep meaning to get back on it. I just... haven't."

That's what someone said to me recently about their bike, untouched for the last few months. No injury. No dramatic reason. Just a slow drift, and frustration at themselves for not snapping out of it.

When we looked at what had actually been happening: months of under-fuelling before the break even started, sleep that had quietly worsened until it just felt normal, recovery that never fully took place, and a body that had decided, without asking, that cycling wasn't affordable right now.

Nobody chooses this. The body decides long before the mind catches up.

If this has been going on for you too, it's worth understanding properly rather than waiting for motivation to come back on its own. A discovery call is a good place to start. Find out more at tessstrom.co.uk.

Training plan fallen away for months, cycling, swimming, running, whatever it was for you? The instinct is often to just push back in and hope momentum returns.

That rarely works, and can sometimes set things back further if under-recovery or low energy availability is behind it.

A better starting point is fuelling and recovery capacity first, training volume second. Consistent, adequate intake, prioritising sleep and nervous system recovery, then gradually building training back up. Testing can clarify what's actually been going on, rather than guessing.

If a regular training plan, whether that's cycling, swimming, running, or anything else, has quietly fallen by the wayside for months, it's rarely about willpower.

Months of under-recovery can build up quietly, long after the original training block or season ended. Adrenal load doesn't reset just because the racing stopped. For some, it's low energy availability, the body running on too little for too long, and deprioritising anything that isn't essential, including the energy for the things you love.

It doesn't stop there either. When the body's resources are limited, it protects what it needs for immediate survival first, and quietly deprioritises the rest: fertility, mood, mental health, and immune function are all commonly affected, often long before anyone connects it back to training and recovery.

If this sounds familiar, it's worth understanding your own specific pattern rather than guessing.

Haven't been back on the bike since last autumn and don't know why?

Not injury. Not really laziness either, if it were, you'd probably know exactly what was in the way.

More often, it's the body quietly protecting itself. Months of under-recovery building up without ever feeling dramatic. Energy reserves running low without tipping into full-blown exhaustion. A nervous system too stretched to have anything spare for the thing you used to love.

The drive didn't disappear for no reason. Something shifted underneath it.

Sound familiar?

Cutting calories, training hard, weight won't move? The fix is often the opposite of what feels intuitive.

Fuel properly around your training, not against it. Add strength work, not just more cardio. Testing (thyroid, cortisol, inflammation and more) clarifies what may be driving it, rather than guessing.

What's felt most frustrating about this so far?

Under-fuelling is usually the last thing anyone suspects, and it's often the answer.

When intake drops too low relative to your training load, your body reads it as a genuine shortage. It slows everything down to protect itself, thyroid conversion, resting energy expenditure, and your performance plateaus right alongside your weight.

Does this sound like where you're at?

It could be cortisol holding onto fat rather than releasing it, training itself is a stressor, and too much on top of everything else can work against you.

It could be your thyroid running underactive, even on a "normal" test.

It could be genuinely under-fuelling, too big a gap between what you're eating and what you're training for can actually slow your metabolism down and stall performance alongside your weight.

There's an answer, but we won't know which one until we look at what's actually going on for you.

What does your training week actually look like right now?

If food-related migraines feel like a guessing game, start with a food and symptom diary that tracks a 48-hour window, not just the day itself. Delayed reactions are common enough that a same-day diary often misses the real trigger.

Gut testing can help build the fuller picture too, especially where gut imbalance is likely playing a part.

If food-related migraines have felt impossible to pin down, here may be why.

Histamine intolerance means histamine builds up rather than breaking down efficiently, and how much builds up varies meal to meal.

Blood sugar swings can trigger migraines directly.

And some reactions are delayed by 24 to 48 hours, so the thing you're blaming today might not even be the actual trigger.

That's exactly why elimination diets so often don't find a clear answer, they assume the reaction happens straight away.

Migraines after eating, but never the same food twice?
It could be histamine (fermented, aged, leftover foods). It could be a blood sugar swing. It could be a delayed reaction that only shows up a day or two later, which is exactly why it never seems to be the same food. It could be dehydration on top of it all.

There's an answer, but honestly, we won't know which one, or ones, until we look at what's actually going on for you.
