On Athletics Club

On Athletics Club, commonly abbreviated OAC, is a professional distance-running organization sponsored by the Swiss sportswear company On Holding AG. The group was established in August 2020 with eight original members and was designed as a performance-focused training environment for elite track and road runners. Its principal base is Boulder, Colorado, a high-altitude location that has become closely associated with American distance running and with the group's Global Team. OAC is not a conventional consumer product line or a mass-participation running club. Its core activity is the recruitment, support, coaching, and development of professional athletes competing in events such as the 1,500 meters, mile, 5,000 meters, 10,000 meters, cross-country, and road distances including the half marathon and marathon. Athletes train collectively, receive coaching and organizational support, and represent On in competition. On also sponsors individual runners who are not formal members of OAC, so the club is one part of the company's wider athlete and performance-marketing ecosystem. The organization operates through a geographically distributed structure. OAC Global trains primarily in Boulder and has included athletes from North America and other regions. OAC Europe provides a European training base under coaches Vincent Guyot and Thomas Dreissigacker, while OAC Oceania is coached by Craig Mottram and Ben Green. This structure allows the group to retain a shared identity while placing athletes in training environments suited to their national, competitive, and logistical needs. The coaching staff associated with the Global Team includes former elite runner Dathan Ritzenhein, Kelsey Quinn, Jason Ross, and Laura Thweatt. The program's public profile has been strengthened by athletes such as Joe Klecker, Olli Hoare, Alicia Monson, Hellen Obiri, Yared Nuguse, Geordie Beamish, and Sage Hurta-Klecker. OAC athletes have produced notable performances in both track and road racing. On August 3, 2020, Joe Klecker and Olli Hoare became the first runners to record sub-four-minute miles on Colorado soil, an achievement notable because of Colorado's elevation and the state's long history without such a result. Hellen Obiri became one of the club's most prominent marathon performers. She won the 2023 Boston Marathon and later won the 2023 New York City Marathon, becoming the first woman since 1989 to win both races in the same year. She then won the 2024 Boston Marathon for a second consecutive victory, defeating Sharon Lokedi by eight seconds. Obiri finished second at the 2025 Boston Marathon. These results have helped position OAC as a visible bridge between elite track competition and high-profile road racing. The club's identity combines professional sport, athlete development, team culture, and technical-brand sponsorship. Its significance to On lies not only in race results but also in the credibility, storytelling, and product-testing opportunities created by a stable group of elite runners. OAC remains an active organization, although athlete membership changes over time as runners join, leave, or continue to receive sponsorship outside the formal team structure.

On Athletics Club was created in August 2020 as a professional training group sponsored by On Holding AG. The founding concept was to assemble elite distance runners in a structured team environment rather than rely solely on individual athlete endorsements. The original group contained eight members, and Boulder, Colorado, became its principal training location. Boulder offers an established distance-running community and high-altitude conditions, making it a distinctive base for athletes preparing for track and road competitions. The club's early public milestone came on August 3, 2020, when Joe Klecker and Olli Hoare ran under four minutes for the mile in Colorado. No runner had previously achieved that mark on Colorado soil. The performance was especially notable because the state's elevation makes middle-distance and distance performances more difficult than comparable efforts at sea level. The result gave the newly formed organization an early competitive identity and connected it with Colorado's running culture. OAC subsequently developed into a broader international structure. The Global Team continued to train primarily in Boulder, while OAC Europe and OAC Oceania provided additional regional bases. The European group has been associated with coaches Vincent Guyot and Thomas Dreissigacker; the Oceania group has been associated with Craig Mottram and Ben Green. Membership has included athletes from multiple countries and competitive backgrounds, with runners specializing in events ranging from the 1,500 meters and mile to the marathon. The Global Team's coaching staff includes Dathan Ritzenhein, Kelsey Quinn, Jason Ross, and Laura Thweatt. The roster has changed regularly as athletes have joined, departed, or continued relationships with On outside the formal OAC structure. The listed Global Team additions include Geordie Beamish, Olli Hoare, and Joe Klecker in August 2020; Sage Hurta-Klecker in June 2021; Mario García and Yared Nuguse in June 2022; Hellen Obiri in January 2022; Sintayehu Vissa in August 2022; Josette Andrews in January 2023; and Olivia Markezich and Ky Robinson in June 2024. Robert Farken and Dylan Jacobs were added in November 2024, while Ryan Ford and Patrick Kiprop were listed as additions in October 2025. OAC athletes have also achieved important results in major road races. Hellen Obiri won the 2023 Boston Marathon in 2:21:38 and the 2023 New York City Marathon in 2:27:23. Her two victories made her the first woman since 1989 to win both events in the same year. At the 2024 Boston Marathon she successfully defended her title, recording 2:22:37 and finishing eight seconds ahead of Sharon Lokedi. Obiri placed second at the 2025 Boston Marathon. Former members have included Alicja Konieczek, Carlos Villarreal, Leah Falland, Carmela Cardama Báez, Morgan McDonald, Tsigie Gebreselama, Maia Ramsden, and Cari Hughes. Some former formal members, including Konieczek, McDonald, Gebreselama, and Ramsden as of January 2026, continued to be sponsored by On. This distinction illustrates that OAC membership and On sponsorship are related but not identical categories. Today, OAC functions as both a professional sports organization and a brand-supported performance platform. Its principal outputs are athlete development, competitive results, coaching expertise, and public representation of On in elite running. Because the team is organized around people and training locations rather than retail products, its roster, coaching arrangements, and regional structure are more central to its identity than a conventional product catalog.
