The Bogotá International Half Marathon, or mmB as it is traditionally known, is an annual road running competition over a half marathon distance 21.0975 kilometres (13.1094 mi) taking place in Bogotá, Colombia in late July or early August. Established in 2000, it holds IAAF Gold Label Road Race status, making it the first and thus far only South American race to achieve this accreditation. The competition features both elite and popular (or recreational) sections within the half marathon and 10K races. Around 45,000 runners take part in the competition's events each year.

Both courses at the race have a point-to-point format. The half marathon course starts at Bolívar Square and heads north past Avenida Jiménez and Parque Nacional, before turning west at Unicentro shopping centre. The course continues heading west, passing the Salitre Mágico amusement park, and finishes at Simón Bolívar Park. The 10K race has identical start and finishing points, but follows a more direct path between the two – heading north on Calle 26 then switching to Calle 53 which goes directly past Bolívar Park.

The elite race has featured a number of high profile runners, including former marathon world record holder and champion Catherine Ndereba, two-time Saint Silvester Road Race winner James Kwambai, Olympic medallist and New York City Marathon champion Joyce Chepchumba and 2005 World Half Marathon champion Fabiano Joseph. The race is not typically conducive to fast times as the city is located at 2,600 meters above sea level, some 8,530 feet, a factor which inhibits long distance runners. However, it is considered a perfect training ground for professional athletes and runners looking to run the World's Marathon Majors in Berlin, Chicago and New York happening in the fall each year.

The Atea Kalmarmilen is a well-established 10-kilometer road race held annually in Kalmar, Sweden, welcoming both recreational and elite runners. The event showcases Kalmar's picturesque scenery, with the course passing notable landmarks such as Kalmar Castle, Stensö, the Old Town, the harbor, Fredrikskans, Lindö, and Ängö, before concluding at Larmtorget in the city center.

The 2025 edition is scheduled for Wednesday, July 30. The main 10 km race will commence at 19:10, following a series of children's races earlier in the evening. Participants who register by July 23 will receive a race-branded shirt upon bib collection. Finishers are awarded a special medal to commemorate their achievement.

The event is organized by Högby IF, with support from sponsors including Atea, Pontuz Löfgren, Barometern, Best Western Plus Kalmarsunds Hotell, Topline, ICA MAXI, and Triumf-glass.

With an eye toward continuing the historic athletic success of 2022, USATF is pleased to announce competitive opportunities for its athletes to secure qualifying marks and prize money, including a new Grand Prix series, as they prepare for the 2023 World Athletics Championships in Budapest, Hungary.
As announced a few months ago, the 2023 Indoor Championships in Nanjing, China have been postponed to 2025.

“We are looking forward to outstanding competitions in the 2023 season, both indoors and outdoors,” said USATF CEO Max Siegel. “Our athletes continue to raise the bar for athletic excellence at home and abroad. We must continue finding innovative ways to help them prepare through competition and providing competitive opportunities closer to home is a major game-changer. Hosting events in large U.S. sports markets is important to the continued growth of track and field and important to building and inspiring a loyal fanbase.”

As a part of the Journey to Gold, USATF will introduce the Grand Prix Series of elite gold-label events. Fans will not only get to see exciting competition from the best athletes in the world, but they will also have the opportunity to participate and engage in the sport in various events during this multi-day series. The goal is to shine a spotlight on USATF athletes, brand, sport, and culture globally.

Waldo 100k Trail Run is mostly single-track trail with more than 11,000′ of elevation gain and an equal amount of loss. There are three major climbs of more than 2,000′ each and two minor climbs of more than 1,000′ each. The highest point is 7,818′ at the top of Maiden Peak and the lowest point is at Gold Lake, about 4,900′.

The name of the race was decided on when it was clear that runners could only ever “see” Waldo Lake from the high peaks and never arrive there. Race director Craig’s wife, Laurie Thornley, warned him that someone might come after him regarding the use of the children’s storybook name, but he decided to chance it. Wanting to add some flavor to the normal prize structure, Craig and co-director Curt added a premium for the racers, The “Find Waldo” award would go to the first runner to reach the top of Fuji Mountain (mile 16), but to win the prize the runner had to complete the race.

And thus, Where’s Waldo 100k was born. It was included in the Oregon Trail Series, and with the fair warning, “It is not a beginner-level ultra and participation in the race should not be taken lightly,” the first race was on the calendar for September 28, 2002. A two-person relay was included to get the numbers up.
