@ludolovesmetal @Max15236 Oropa au Giro. Jalabert dans les derniers à être rattrapé il me semble

@laflammerouge16 @velowire_com Will be Étape du tour 🤔 and Bourg D’Oisans - Orcieres Merlette day after 🤷‍♂️

Après c’est toujours compliqué à quantifier … mais depuis que je pratique je n’ai jamais aussi bien supporté la chaleur.
Pour le reste je fais confiance aux études pour moi et mes élèves …

Carbohydrate strategies for elite long distance endurance 🚴

PRE-COMPETITION 🔋

⏱️ Event < 90 min = 6 - 12 g/kg in 24-hr prior
⏱️ Event > 90 min = 10 - 12 g/kg/day in 36 - 48-hr prior
❌ Do not exceed 75 g carbs in final pre-race meal
⏰ Consume pre-race meal at least 2-hr prior to race
❌ Do not consume high doses of carbs 60 - 30 min prior to race
🥤 Mouth rinse may be preferable

DURING COMPETITION 🎽

⏱️ Events > 150 min = 60 - 90 g/hr
⏱️ Events 60 - 150 min = 30 - 60 g/hr
⏱️ Events ≤ 60 min = carb mouth rinse

POST-COMPETITION 🏆

After glycogen depletion…

⏰ Muscle glycogen takes 24-hr to recover
⏰ Liver glycogen takes 11-hr to recover

⏳ Within 4-hr = 1.0 - 1.2 g/kg/hr carbs
⏳ Within 24-hr = 8 - 10 g/kg

📈 Sustaining 8 g/kg/day for 36 - 48-hr can lead to muscle glycogen supercompensation

CARBOHYDRATE PROPERTIES 🔬

👉 Combined glucose + fructose (2:1) to reduce GI discomfort

👉 Highly branched cyclodextrin = low osmolality, fast gastric emptying, reduced GI discomfort

👉 Gels = fast gastric emptying / absorbing

🥤 6% glucose or 8 - 10% glucose+fructose solution is advised

🥤 Some athletes see benefits with high concentration solutions ~ 200 g/L

SYNERGISTIC NUTRIENTS 🧂

🥤 Carbs 0.8 g/kg/hr + 0.2 - 0.4 g/kg/hr protein post-exercise to speed glycogen recovery

🧂 Sodium = 30 - 50 mmol/L to enhance glucose uptake and utilisation

☕️ Caffeine = 6 - 9 mg/kg 60-min prior to exercise to increase fat oxidation and spare muscle glycogen

⏱️ In 4-hr post-race = 1.2 g/kg carbs + 8 mg/kg caffeine accelerates muscle glycogen recovery

GASTROINTESTINAL FUNCTION 🛠️

Training the gut protocol ⬇️

🗓️ 10 training sessions over 2-wks
🫀 60% VO2max for 60-min
⏱️ 30g carb gel at 0, 20, 40-min

= reduced GI discomfort + enhanced performance 🏆

INDIVIDUAL DIFFERENCES 🙋‍♂️

Test where possible and personalise strategies based on following factors…

👉 Age / Weight / Sex / Preference

ALTITUDE 🏔️

Athletes may benefit from improving GI function, prioritising glycogen loading and increasing habitual carb intake 📈

HEAT & HUMIDITY 🥵

👉 Amplified demand for endogenous carbohydrate
💧 Shift to fluid sources of carbs to maintain hydration status
🧊 Practice carb ice slushy ingestion

COLD ENVIRONMENTS 🥶

⚠️ Increased risk of glycogen depletion and hypoglycaemia
🌡️ Consume carb solutions with warm water to elevate core temp
🩸 Real time blood glucose monitoring may be useful

COMPETITION ANXIETY 😰

Anxiety can affect appetite, increase GI issues and increase glycogen depletion due to catecholamine release 🧠

Athletes who experience anxiety may benefit more from advanced carb loading strategies and increased total carb intake ✅

Carbohydrate intake for endurance performance is far from simple, it’s not just about eating a big bowl of pasta the night before 🍝

@mproprecycling @ammattipyoraily I think too... but Italia 🤷‍♂️
why not Zoncolan x2 by ovaro and priola same as me last Sunday 😂

[loui @looflol]

Yo @LeTour this is a good stage please include this stage in the 2025 tour that would be nice

@ThibaudChambre Le plateau de beille n'est pas en pente constante ;) oui même sans être pro tu peux parfois rouler à 30 sur cette montée ;)

[Tim Drct @DrctTim]

Je trouve ça vraiment dommage de pas nous avoir sorti l'enchaînement Agnel/Izoard/Galibier, c'est la seule étape de haute montagne avant la fin de la 2e semaine, autant assumer et mettre des vrais cols plutôt que des montées à 5%

[Tour de France™ @LeTour]

😡 Don't cross the road in front of the riders!

😡 Ne traversez pas la route devant les coureurs !

Essa molecada é um absurdo.

Nada de tecnologia, frufrus, só um objetivo e play.

Por mais ciclistas assim por aqui!
