The Challenge
Parks & Trails Organisation, a group of passionate hiking enthusiasts, envisioned creating Hong Kong's first comprehensive 65km coastal trail by connecting existing promenades and hiking paths around Hong Kong Island.

The challenge was to create an engaging digital platform that would:

- Support both leisure participants and competitive racing groups
- Build a community of environmental and cultural ambassadors
- Provide comprehensive event management and participant tracking capabilities
