Event Detail
Borneo 100 Miler 2023 ran over 3–5 June through varied trails, wetlands and paddy fields in rural Sabah, with views of Mount Kinabalu and the South China Sea. The 100-mile main course started at 6:00 am on 3 June, alongside a 25K course. ITRA recorded a 165K race distance. ARC currently lacks a 100-mile/165K tag, so only the verified 25K tag is selected and the true headline distance is clearly documented here.
