Stick with it for 3–4 weeks and your heat tolerance will skyrocket. ☀️💪. 🔥 Bonus tip:. Strategic heat training not only helps you survive hot weather — it can actually boost performance once temps drop. Train smart now, fly later. 😉.

But it’s not all bad news. Here’s how to fight back and adapt smartly:. 1️⃣ Train during the coolest hours .2️⃣ Lower intensity until you’re heat-acclimated.3️⃣ Pick shady, breezy routes.4️⃣ Stay ahead of hydration — don’t wait to feel thirsty .5️⃣ Use strategic cooling.

In a study coming out soon, we analyzed nearly 400 endurance athletes (cycling, triathlon, running). The results? Performance drops exponentially as temperature rises. Some athletes lost >40% at 40°C (104°F). 🥵. Heat hurts.

🔥🏃‍♂️🚴‍♀️ Feeling cooked during your runs or rides?. It’s not just in your head — heat cranks up your RPE and melts your endurance performance. 🧵Let’s talk about what the data says and how to survive (and thrive) during heat waves:

Key point for today’s stage:. If the climb is tackled hard from the bottom, we’ll see the first VO2max effort preceded by proper recovery and a final sprint — unlike previous glycolytic climbs with incomplete recovery. Expect to see some new faces up front and others fading.

For those thinking Vingegaard and Pogi are on a similar level because Vinge followed him yesterday:. At 24��km/h on an 11.5% gradient, sitting on the wheel gives ~8% draft—about 40–45 watts saved for Vini. Now, try to attack instead of following….#TDF2025.

3/ So much for the idea that women’s fatigue resistance makes them better ultra athletes. Nope — men still dominate these brutal events. And the difference stays consistent across all sports we checked.

2/ The result? . Women are still 22% slower than men on average (counting winners and podium finishers). That’s not a tiny difference — it’s HUGE in the world of elite sport. As an example, commonly reported figures for traditional endurance events are in the 12-14% range.

1/ Media usually report that women might be closer to men in super long races. So, do women actually outperform men or at least match them in ultras (6+ hours)? . We dug into a century of 20 events across swimming, cycling, running & triathlon.

Can women really outperform men in ultra-endurance events? . What's the true performance gap?🏃🚴‍♀️🏊. We attempted to answer these questions in our recent systematic review and meta-analysis. Let's go with a brief thread 🧵

When structured work pays off. I started coaching this rider in November, as he transitioned from U23 to Pro Continental. In just 6 months, he’s gained 20–50 watts from 30s to 5min. Even I didn’t expect such a jump so quickly.

7/ So maybe the real question isn’t “Should we ban power meters?”. Instead:. 👉 How do we educate fans on their real role in modern racing?.👉 How do we embrace technology without letting it dictate the soul of the sport?. Let’s shift the debate.

6/ The real value of the power meter?. 🔍 Post-race analysis. It’s about learning, adjusting training, and improving strategy for next time. Not controlling every move mid-race.

5/ Sure, in a time trial or final climb, they might help with pacing. But in most decisive moments—attacks, chases, breakaways—riders go by feel, race context, and instinct. Not watts.

4/ So removing the power meter wouldn’t change as much as people think. These athletes already know how to suffer smart. Second:. 📊 Power meters are used more for analysis than for real-time tactics.

3/ As a coach, I’d like to offer two key reflections from experience:. First:. 🚴‍♂️ Pro cyclists don’t need power data mid-race to pace themselves. In lab tests, they can match perceived effort with power output almost perfectly. They’re highly trained to read their body.

2/ On the other hand, power meters are now deeply embedded in cycling culture. For a younger audience raised on data, numbers are part of the story—not a threat to it. They help understand the sport on a deeper level.

1/ Supporters of a ban say racing has become too calculated. They long for epic solo breakaways, heroic blow-ups, and instinct-driven attacks—where suffering and tactical guts outweigh data and pacing charts.
