After the finish

Recovery
& timing

What's actually going on in your body after a hard ride? And more to the point: what can you do about it?

You step off the bike. Legs empty, jersey soaked, and that unmistakable feeling that you left it all out there. Great moment. But what you do next matters almost as much as the ride itself.

Because recovery isn't an afterthought. Get it right and you're back at the start line fresh tomorrow, or next weekend. Get it wrong and you drag today's fatigue into your next session. And the one after that. Until there's nothing left in your legs.

01
What happens

Three things at once

A long effort drains three tanks. You want all three back up to level as fast as you can.

01 · Fuel
Refilling glycogen
Your tank is empty. The sooner you refuel, the sooner your body can stop surviving and start building.
02 · Building blocks
Protein for your muscles
Around 20 to 30 grams of protein is enough to get your muscle repair running at full tilt. Whey works best here, because you absorb it quickly.
03 · Fluid
Rehydrating with salt
Sodium pulls double duty. It makes you thirsty, and it makes sure the fluid you drink actually stays where you want it.
02
Timing

That "golden half hour"
is less strict than you think

What you often hear
"You've got 30 minutes. After that, the train has left."
What the numbers say
Your muscle repair keeps running at full power for hours, peaking somewhere between 12 and 24 hours after the ride.

And refilling your glycogen works the same way. It goes fast in the first hours, but you're not completely full again until a day or so later. So what really counts over the long run is how much carbs and protein you take in across that whole day. Not whether you down your shake within thirty minutes.

That said, timing isn't nonsense either. If you're short on recovery time, say during a stage race, on a double training day, or when you're back on the bike early tomorrow, it does pay off to be quick. Simply because the clock is working against you.

In short

Miss that half hour now and then? No big deal. Just make sure you get enough in over the day. That matters far more in the end.

03
The shake

Four things it should have

01

Glucose and fructose, 2 to 1

Your gut has two separate doorways for carbs. Use both at once and you absorb more, faster, without stomach trouble. Your liver benefits most: it refills almost twice as fast as with sugar from a single source.

02

Good whey

Isolate ideally, or a mix of isolate and concentrate. Isolate is the purest, goes down lightning-fast and is loaded with leucine. And that just happens to be the amino acid that flips the switch on your muscle repair.

03

Electrolytes, sodium first

Sweated buckets? Then feel free to add some salt to your shake. Sodium keeps the fluid where you actually want it, instead of you passing it straight through.

04

The right ratio

Roughly 3 to 4 parts carbs to 1 part protein. That's the range you keep seeing in the research. One small thing: that protein mainly helps your glycogen when you're running low on carbs. Eating enough? Then the protein's real value is in the muscle repair.

05
The extra layer

Tart cherry

Sour cherries, especially the Montmorency and the Vistula, are loaded with anthocyanins and other polyphenols. Those compounds give the juice its deep red colour, and they're known for calming inflammation.

A nice addition, not a miracle cure.
Where it works
In cyclists who drank cherry juice during a simulated stage race, you saw less inflammation and less oxidative stress than in the control group. It seems to pay off mostly when the efforts come thick and fast.
Where it falls short
After strength training, other researchers found no difference in muscle soreness or inflammation markers. And as with other antioxidants: taking it every day can actually dull your training stimulus.

The protocol

How the pros

Firstright after the finish
How the pros do it

Tart cherry first

With the pros, the cherry shot goes down first, before the shake. A sachet dissolved in water, to tackle the inflammation and oxidative stress straight away. During heavy spells, at least, no need to do it daily.

Right afterthe basics

Then the recovery shake

As soon as it's practical, mixed with water. Carbs, protein and salt all in one go. That's what your recovery really runs on.

−7 to −5dbefore a peak race

The loading phase

In the days before an important race you take tart cherry daily, to build up the effect in your muscles. Save this for your busiest racing spells.

Rest of daythe basics

Keep topping up

One shake won't cut it. Spread your carbs and protein across the rest of the day. That's what fills your tank all the way back up.

Heads up

On ordinary training days, leave the tart cherry alone, at least if you want your training to land properly. Think of it as a weapon for your busiest weeks, not everyday fare.

To wrap up

Recovery is a choice,
not a deadline

What it comes down to: make sure you get enough carbs, protein and salt in the hours after a hard ride. And keep it up for the rest of the day.

A good shake gets your recovery going. Tart cherry is that bit extra for the toughest moments. Not a replacement for the basics, but a smart addition.

Knowledge & tips

Food supplements don't replace a varied diet and a healthy lifestyle. Stick to the recommended dosage. Everyone's different, so always try a new product in training first, never for the first time on race day. In doubt, or dealing with a medical condition? Have a quick word with your doctor or dietitian.
