Radar Stemma: Huawei Watch Launch, Mizuno Atenas & More

Return of the Mizuno Atenas Circuit to the national calendar

One of Brazilian road running's most traditional race series is getting a major refresh in 2026. Mizuno has reclaimed the naming rights for the Iguana Sports project, newly rebranded as the Circuito Mizuno Atenas, reviving the historic partnership first established in 2010 and 2011. The series expects to welcome around 32,000 runners across three progressive stages designed for continuous athletic development.

The circuit's schedule has been strategically organized throughout the year: the Run Faster stage takes place on March 15 (5K, 10K, 15K, and 21K); Run Stronger on June 21 (6K, 12K, 18K, and 25K); and Run Longer wraps up the season on October 18 (7K, 14K, 21K, and 28K), offering intermediate race distances for structured endurance conditioning.

The event blends road racing with lifestyle entertainment tailored for the running community.

The tour's first stop in the Southeast will be in Vitória (Espírito Santo) on April 13, with registrations now open. Shortly after, Rio de Janeiro will host the race on April 23, solidifying the circuit's nationwide growth strategy.

The initiative builds upon a similar project launched at Villa-Lobos Park through Orla TotalPass.

The move has sparked active discussions across the local sports community regarding the balance between corporate brand activations, public infrastructure upkeep, and preserving the democratic, open-access nature of urban public parks.

Pepe Fiamoncini breaks manual treadmill Guinness World Record

Brazilian ultramarathoner Pepe Fiamoncini, 35, set a new official Guinness World Record by running 188 km in 24 hours on a non-motorized manual treadmill. The endurance challenge took place on February 4 and 5 at Rio Academia Ipanema in Rio de Janeiro.

Unlike standard motorized treadmills, curved manual treadmills rely entirely on the runner's own propulsion with every stride, requiring immense physical endurance and mental fortitude across the equivalent of more than four back-to-back marathons.

Rio Marathon adds extra entries and returns to its classic route

Organizers of the Rio Marathon announced an additional release of 5,000 bibs for the 42K distance, raising the total cap to 20,000 marathon finishers. The course has also returned to its iconic coastal layout, starting at Praia da Reserva in Recreio dos Bandeirantes and finishing at Aterro do Flamengo.

Featuring just 21 turns over the entire 42.195 km distance, the scenic course hugs the coastline through São Conrado, Leblon, Ipanema, Copacabana, and Botafogo. Reducing narrow bottlenecks through the historic downtown area in the early miles will provide smoother pacing and flow for participants.

The chaotic history of the 1904 Olympic Marathon

Among track and field's historical curiosities, the marathon at the St. Louis 1904 Olympic Games remains one of the most bizarre events ever recorded. Held under blistering heat and across dust-choked dirt roads, the race offered only a single official water station along the entire route.

Eventual gold medalist Thomas Hicks crossed the finish line in a state of near collapse after his handlers administered doses of strychnine—a toxic rat poison commonly used as a stimulant at the time—mixed with brandy. Another competitor, Fred Lorz, crossed the line first but was promptly disqualified after admitting he had hitched a ride in an automobile for roughly 11 miles of the course.

The milestone carries special family significance: his 23-year-old granddaughter, Mia, also earned a Boston Qualifier with a time of 3:14:00. Together, they are set to become the first grandfather-granddaughter duo to run the world's most storied marathon in the same edition.
