Operation 100 Miler
Taste trial done. Now onto the battle ground. This week a legend from our crew takes Lime Infusion on the Grampians Peaks Trail 100 miler, 5 to 8 November: 162 km and about 7,700 m of climbing. The GPT100 is our test track. Every milestone gets logged so you can follow the build to launch in Feb 2027.
The test
- Grampians Peaks Trail 100 miler (GPT100)
- 5 to 8 November, Grampians National Park
- 162 km and about 7,700 m of climbing
- Lime Infusion carried and eaten on course
Why we're doing this
- A 100 miler is the toughest real-world test we can give the candy: over 160 km and about 7,700 m of climbing
- Late in a long effort, taste, stomach and energy are all under pressure. That's when a candy has to work
- What happens on the course shapes the recipe before launch
- Every milestone is logged on the development blog, so you can follow the build to launch in Feb 2027

Four months in, and the kitchen smells like lime
We're about four months into R&D, starting right back at the formulation stage. Batch after batch, Pete and mates have been mixing, pouring, cutting and taste testing at the kitchen bench, tweaking one thing at a time until it feels right on a long run. Here's where we're heading next, and we'd love you along for it.
