One Year of Radar Stemma: Behind the Scenes and Statistics
Radar Stemma reached its 52nd episode, marking a full year on the air. What began as a weekly recap of road running, trail running, and open water swimming has established itself as a hub for community culture and behavioral analysis, consistently blending in-depth product reporting, market trends, and race coverage with engaging discussion.
The show's structure is powered by editorial research led by Iara alongside data analysis and statistical reporting by Carlos Guimarães.

Columbia Takes Over Naming Rights for Indomit Pedra do Baú
Columbia Brazil kicked off the trail running season by officially securing the naming rights for the Indomit circuit for two years, covering both the Pedra do Baú and Bombinhas stages. The opening race brought together roughly 2,500 runners in São Bento do Sapucaí, São Paulo, on one of the country's most technical and demanding courses, featuring distances ranging from 7 km to 80 km.
The 21 km race, featuring an elevation gain of approximately 1,200 meters, saw Lucas Ferreira claim victory in the men's division with a finishing time of 1:51:04. The event village set up at the Pousada do Quilombo helipad stood out for its direct views of Pedra do Baú and comprehensive aid station support across the mountain range.
New Balance 15k Draws Over 10,000 Runners to São Paulo
The New Balance 15k São Paulo welcomed more than 10,000 athletes across 7.5 km and 15 km distances, passing through iconic landmarks such as Pacaembu Stadium, the historic downtown district, and the Minhocão elevated highway. The course tested participants with the capital's signature rolling hills and elevation changes.
Organized by Run Sports, the event expanded the participant experience well beyond the finish line. The race expo offered recovery services featuring pneumatic compression boots, product customization, a styling station, and an upgraded runner's kit complete with arm sleeves and technical running socks.
Eliud Kipchoge Confirms Schedule and Visit to Brazil
Two-time Olympic champion Eliud Kipchoge will travel to Brazil for a series of New Balance activations tied to the Porto Alegre 42K Marathon. The visit, planned over the course of six months following the New York City Marathon, aims to replicate the enthusiasm seen during his recent tour in Asia, which drew thousands of fans and extensive media coverage.
The Kenyan distance runner will spend a week in the country, arriving on a Tuesday and departing the following Monday. The itinerary includes two event formats: a keynote lecture open to the general public in an auditorium setting and an intimate session limited to 200 attendees. A portion of ticket proceeds will benefit local social and community assistance programs.
Pacer Controversy at the Berlin Half Marathon
The Berlin Half Marathon reignited debate regarding the role of pacemakers in elite road racing. Kenyan pacer Dennis Kipkemoi, hired by organizers to set a 59-minute pace through the final kilometers, remained in prime physical shape ahead of the lead pack and had a clear path to victory. However, race regulations strictly barred designated pacers from contending for the overall title.
The incident drew comparisons to other historic moments in distance running, including the 2003 Berlin Marathon where Paul Tergat set a world record after starting as a pacemaker, as well as instances at the Seville Marathon where pacemakers carried their lead through the tape. The scenario continues to divide analysts over whether physically capable runners should be disqualified from taking first place.
April Fools' Prank at the New York City Marathon
Organizers of the New York City Marathon celebrated the 50th anniversary of the five-borough course by releasing an April Fools' Day joke. The fictional announcement stated that the 2026 edition would return to the original 1970 format, which consisted entirely of repeated loops within Central Park.
The inaugural 1970 edition featured just 55 entrants, a $1 entry fee, and a winning time of 2:31:00. The post quickly made the rounds across the international running community before organizers clarified it was a tongue-in-cheek nod to the race's heritage.
Nike Steps Up Ambush Marketing in Boston with Heartbreak
Ahead of the Boston Marathon—an event sponsored by Adidas for nearly four decades—Nike rolled out a series of cultural and grassroots community activations across the city. The operation's central hub was situated at Heartbreak Hill Running Company on Commonwealth Avenue, near the 31 km mark of the course.
The Swoosh scheduled product drops, community shakeout runs with local clubs, and curated events for recreational runners. The move highlights the ongoing rivalry among major sportswear manufacturers seeking cultural relevance and organic visibility around the World Marathon Majors.
Sacral Stress Fracture Rules Connor Mantz Out of Boston
In elite competitive news, American marathoner Connor Mantz withdrew from the Boston Marathon following a diagnosis of a stress fracture in the sacrum, located at the base of the spine. Mantz had been enjoying strong momentum on the international circuit and entered the season as one of the primary American contenders for the race.
Market Headwinds at Nike and the Rise of Super Trainers
Nike continues to navigate corporate restructuring under CEO Elliott Hill, underscored by a recent drop of up to 13% in the company's stock price. The downturn stems from market share losses in Asia, lower sales at subsidiary Converse, and ongoing adjustments to wholesale distribution strategies with brick-and-mortar retailers.
Industry analysts also note a shift in consumer buying patterns: while demand for dedicated carbon-plated racing shoes has leveled off, the 'super trainer' segment—non-plated or flexible shoes featuring high-energy-return foams, such as the Adidas Adizero Evo SL, Asics Superblast, and Mizuno Neo Vista—is experiencing rapid growth in everyday training rotations.
Olympikus Teases Upcoming Corre 5 Release
Brazil's domestic market is also preparing for new product launches. Olympikus took to social media with teaser posts hinting at the fifth generation of its performance line, the Corre 5. The brand has maintained a steady release cycle across its running lineup, expanding its footprint in road races nationwide.
