This week in The Colosseum...
Arda Saatçi's 604-kilometer Red Bull Cyborg Season Ultra 600 from Death Valley to Santa Monica Pier — 372 miles, 123 hours, over a million live viewers, and a message that your limits are further away than you think. He didn't hit the 96-hour target, but the story of why that didn't matter is the headline.
A 47-year Karolinska Institute longitudinal study tracking the same 427 individuals from age 16 into their 60s found that physical capacity peaks around 35 and declines from there — across aerobic capacity, strength, endurance, and power. The hopeful part: adults who became active later still saw meaningful 5–10% improvements. The decline starts earlier than people think, and the body still adapts later than people assume.
The Enhanced Games are heading to Las Vegas — performance-enhancing drugs under medical supervision, openly. We get into what it signals about hormone optimization, peptides, and biohacking moving mainstream, and where the line between elite sport and openly enhanced spectacle is going.
Quick hits include Jake's
20:38 finish at the Stony 100-miler (400 laps around a track), an 80-year-old shaving three hours off his Badwater time three years after a DNF, William Goodge running the Los Caños de Florida 100, Hunter McIntyre's man camps and the case for mentorship in fitness culture, Farm Fitness in the UK building a HYROX-first community gym model, Dr. Riccardo Ceccarelli's mental performance labs training F1 drivers and tennis pros for "mental economy," and Whoop rolling out telehealth visits and AI features as wearables move from tracking to platform.
Study of the Week: a systematic review and network meta-analysis in Frontiers in Public Health — 29 randomized controlled trials, 1,300 middle-aged and older adults — comparing aerobic and resistance training intensities for glycemic control and cardiorespiratory fitness. The takeaway: resistance training is metabolic training. Muscle is where your body decides what to do with glucose, and strength work moves the needle on HbA1c and fasting glucose in ways most people never connect to the weight room.
