Clark One Big Run returns May 3

Clark One Big Run is set for Sunday, May 3, 2026, at Filinvest Mimosa+ in Clark, with races from 3 kilometers to 42 kilometers. (active.com) The event listing says this is the race’s third year and names the Ateneo Graduate School of Business Clark Students and Alumni Association Inc. as organizer. Philstar reported the group is staging it with Clark City Marathon. (active.com) (philstar.com) Registration pages list five categories: 3 kilometers, 5 kilometers, 10 kilometers, 21 kilometers, and 42 kilometers. The race window runs from 2 a.m. to 9 a.m., according to Philstar’s event report. (takbo.ph) (philstar.com) The run is being pitched as more than a fitness event. The Active listing says it is meant to build “health, resilience, and community” and to promote Clark as a sports-tourism and wellness destination in Central Luzon. (active.com) Philstar said the race will serve as a fundraising vehicle for the association’s socio-civic projects, tying the event to community programs rather than only competition. That framing matches a broader pattern in Philippine road races, where organizers pair mass-participation runs with charity or civic campaigns. (philstar.com) (pinoyfitness.com) Clark is already a regular host for large runs, and Filinvest Mimosa+ has become a repeat venue for endurance events in 2025 and 2026. Event calendars show other races there this year, including Great Run Clark on March 28. (jcirevents.myruntime.com) (mimosaplus.com.ph) Runner perks are also part of the pitch. Organizers say all finishers get medals, while 21-kilometer and 42-kilometer finishers also get shirts; registration packages include a bib with radio-frequency identification timing, a singlet, and a drawstring bag. (takbo.ph) (philstar.com) Third-party race pages list entry fees from 800 Philippine pesos for 3 kilometers to 2,200 Philippine pesos for the marathon, though the primary registration page is the authoritative place to confirm availability and final pricing. (takbo.ph) (active.com) Race-kit claiming is scheduled for May 1 and May 2 at Cycles and Brew Clark, with limited claiming on race day at the event area, according to the Mapometer listing. For Clark, the bigger point is that another mass run is being used to pull students, alumni, local runners, and visitors into the same public event space. (mapometer.com) (active.com)
