Mana Cycle Club had completed an ascending trail from Kiwi Crescent in Tawa that would take riders from the suburb of Tawa into Spicer Forest and beyond to Rangituhi trails. The Club were keen to extend this trail into a loop ride by building a trail that looped back down to Tawa. Their volunteers embarked on the first half with a hand build project and Trails Wellington then joined the party and offered to build the second half with the help of machinery. Hence the name a Game of Two Halves (Kēmu o Rua Haurua). The top half is narrow, tight, twisty and traverses along the terrain under Turbine Road, including two boardwalks. Once it reaches near the southern boundary the character changes to wide sweeping corners with jumps and rollers.
