- Fueling a 100 km ride vs. a 300+ km ride: what actually changes
Why strategy shifts as rides stretch from a few hours to all day and beyond.

Flavor drops, freeze-dried fruit, hibiscus, and other easy ways to fix a boring bottle.
- What the chart actually shows: from bottle to bloodstream
A line-by-line walkthrough of the simulation — intake, gut, absorption cap, and deficit.
- Running vs. cycling: how carb needs and absorption really differ
Your gut's absorption ceiling doesn't change between running and cycling — but your practical target should. Here's why.
- Homemade rice cakes: a real-food recipe for when gels get old
A simple rice, coconut, and date bar — the carb count per piece, and why real food beats another gel late in a long ride.
