The Norwegian 4x4 has landed!

Gear up and get ready—we just dropped a brand-new Norwegian 4x4 Workout into BigRingVR. This isn't just another interval session to help you kill an hour; it’s the training protocol that has taken the sports world by storm, turning podium-chasers and weekend warriors alike into high-output aerobic machines. If you’ve noticed athletes suddenly obsessing over "lactate threshold" and "VO2 max" more than their post-ride espresso, this is why.

The Science of the Suffer

The Norwegian 4x4 (four minutes of high intensity followed by three minutes of active recovery) is backed by serious science from the Norwegian University of Science and Technology (NTNU). By hovering right at that 90–95% heart rate sweet spot, you are performing a fundamental recalibration of your stroke volume and aerobic ceiling. Studies have shown this specific formula is a powerhouse for performance, with some participants seeing a 10–13% jump in VO2 max in just a few weeks.

The "Metabolic Vacuum" Effect

Beyond just engine size, this workout is a masterclass in lactate clearance. While you're in that four-minute "red zone," your body is flooding the system with lactate—which is actually a high-octane fuel source. The real magic happens during those three-minute active recoveries. By staying in motion, you’re training your slow-twitch muscle fibers to act like a metabolic vacuum, upregulating MCT transporters to suck up that lactate and burn it for energy. This builds incredible metabolic flexibility, teaching your system to clear the "burn" before it can slow you down.

Longevity as a Performance Metric

We aren’t just trying to make you faster so you can drop your friends on the local group ride. This protocol is a massive win for health and longevity. VO2 max is one of the strongest predictors of all-cause mortality—a better indicator than traditional markers like smoking or high blood pressure. While you’re huffing and puffing through a virtual pass, your body is busy reducing your "biological age" and strengthening your vascular system. It’s the ultimate two-for-one deal: look like a pro on the bike today, and keep the engine running smoothly for decades to come.

Fresh Terrain for the Pain Cave

To keep your mind off the internal combustion happening in your quads, pair this workout with our latest high-fidelity route releases. We’ve been busy adding a massive variety of global terrain:

The winding curves of the Vrsic Pass in Slovenia.
The rugged, low-density trails of Sandstone Peak in Malibu.
The high-altitude air of Madonna di Campiglio in Italy.
The relentless gradients of Mount Buffalo in Australia.

No Fluff, Just Ex*****on

The Norwegians have cracked the code on aerobic endurance—you only have to look at their dominance in the Winter Olympics to see the proof. This workout is hard, it’s effective, and it’s probably going to make you sweat enough to ruin your favorite rug.

Log in, find the "Norwegian 4x4" in the library, and let’s see what you’ve got. The pain is temporary, but the physiological adaptations are permanent.

Cheers!

Mount Buffalo is widely considered one of the most iconic cycling destinations in Australia, famous for its steady "European-style" climb and breathtaking alpine views. The ascent from the park entrance to the Mount Buffalo Chalet is a bucket-list ride for road cyclists. It is a consistent 20km climb with a manageable average gradient of roughly 5%, making it an excellent "tempo" climb where you can settle into a rhythm.

Mount Buffalo is one of the pillars of the 7 Peaks Ride challenge. This is an "at-your-own-pace" cycling challenge that traditionally runs during the alpine summer (usually from late October to April). To complete the challenge, cyclists climb the seven peaks of Victoria’s High Country and collect "stamps" for their passport (either physically or via an app/Strava).

Mount Buffalo National Park, located in the alpine region of Victoria approximately 200 miles northeast of Melbourne, is an "island in the sky" characterized by its dramatic granite plateau and sheer 300-meter cliffs. Established in 1898, it is one of Australia’s oldest national parks and serves as a unique ecological haven, home to over 550 native plant species, including the rare Buffalo Sallee which grows nowhere else on Earth. The landscape is dominated by massive granite tors—giant rock formations weathered over millions of years—and diverse ecosystems ranging from peppermint forests at the base to twisted snow gum woodlands and alpine wildflower meadows on the plateau.

For visitors, Mount Buffalo is a versatile all-seasons playground that offers everything from tranquil nature walks to high-adrenaline adventures. During the warmer months, explorers can hike over 90 kilometers of trails, such as the steep climb to The Horn—the park's highest peak at 1,723 meters—or swim in the crystal-clear pools of Ladies Bath and Eurobin Falls. The park is also a premier destination for rock climbing, hang gliding, and camping by the shores of Lake Catani. When winter arrives, the plateau transforms into a snowy wonderland, attracting families for tobogganing at Dingo Dell and cross-country skiers to its 14 kilometers of groomed trails. Throughout the year, the historic Mount Buffalo Chalet, built in 1910, stands as a landmark of the park's long history as a beloved mountain retreat.

Cheers!

Madonna di Campiglio, an iconic Giro ride from Italy is now available online!

Madonna di Campiglio, Trentino-Alto Adige, Italy

Distance: 20.22 km

The ascent from the south begins in the village of Carisolo, where the road splits from the valley floor to follow the Sarca di Campiglio stream. Geographically, this climb serves as a stunning transition zone between two geological giants: to your left lies the Adamello-Presanella group, characterized by dark, volcanic tonalite and massive glaciers, while to your right rise the pale, jagged limestone spires of the Brenta Dolomites, a UNESCO World Heritage site. The route is a steady, rhythmic grind of about 15 kilometers with a 6% average gradient, weaving through the pine forests of the Adamello Brenta Nature Park. As you pass through the sun-drenched terrace of Sant’Antonio di Mavignola, the valley widens, offering a panoramic "theatre" of rock that has made this one of the most aesthetically celebrated climbs in the Italian Alps.

Historically, this road is defined by the soaring highs and tragic lows of Marco Pantani. It was on these slopes in 1999 that "Il Pirata" delivered one of his most legendary performances, attacking with such ferocity that he rode the final 5 kilometers at nearly 30 km/h to claim the stage victory in the Maglia Rosa. However, the climb is equally remembered for the following morning, when Pantani was famously expelled from the Giro d’Italia due to high hematocrit levels—an event that signaled the beginning of the end for Italy’s greatest climber.

Since then, the climb has remained a pilgrimage site for cycling fans, hosting modern battles like Ben O’Connor’s 2020 stage win and continuing to feature in the Giro’s high-mountain drama, bridging the gap between the rural traditions of the Val Rendena and the high-society "Pearl of the Dolomites" at the summit.
