The Force is back! Singapore's oldest and most established trail race is back again for 2025 under the banner of Buff Forest Force Run Series. Going back to 2017 when Forest Force Run was born, we have carried on organising our signature race which had evolved from a full blown trail race to one of a hybrid trail & PCN in the post COVID 19 era. Massive changes implemted in the post COVID 19 era has resulted in changing our race format to include less trails and more Park Connectors as regulated by the relevant nature park authorities. Thus Buff Forest Force Run was conceived as a special hybrid race of 50% trails and 50% PCNs. This new hybrid format was introduced in 2023 to great success and we are now in the 3rd edition of this hybrid format.
This year's edition comes with a gradual distance progression categories of 10km, 20km, 30km and 50km. The 4 categories will held on 3 seperate days. Are you game for it? If you are, then read on more to find out the dates and venues!
The 20km, 30km & 50km are UTMB Index certified races. Applicable for those who are seeking to participate in the UTMB World Series of races.

RACE INFORMATION
Due to the non availability of major sections of trails due to new post – pandemic restrictions, the trail sections in the current race routes have been reduced. We had to improvise as much as we were allowed to by the relevant Parks authorities. Buff Forest Force Run Series is an unorthodox hybrid race which consists of a wide variety of terrain. It is not to be mistaken for as a purely trail race which it is not. However trails make up for at least 50% of the race routes for the 20km, 30km & 50km.
