The Glass
Half Full

Brisbane's 50km Trail Ultra
Take on an Ultra Challenge

The Glass Half Full 50km

While The Guzzler is the main event of the weekend, the Glass Half Full packs a punch of its own, taking you around some spectacular and challenging trails. We'll show you what locals know and love about our green city, just how much fun and how much nature you can reach directly from Mt Coot-tha, completely on foot, completely on trails! You'll tour two of our reservoirs in the order they were built, soaking up fire trails, single track, rolling hills and some mean ones too! Let us take you on an adventure in our backyard.
