Free tools that pull weight.
Small calculators for the parts of training nutrition that a single macro number can't cover. Free to use, no signup, no upsell.
Tool 01
Hybrid athlete macro calculator
Weekly training-day macros for hybrid athletes. One weekly calorie target split into rest-day, easy-day, and hard-day macros so carbs rise with training demand.

- Lose, maintain, or build with rate of change
- Mifflin-St Jeor BMR, cited methodology
Tool 02
Endurance carb loading
48-hour pre-race fueling plan for endurance runners. Daily loading targets, race-morning meal, and in-race grams per hour, scaled to your weight and finish time.
- Half marathon through 100 mile
- Loading + race morning + in-race, one plan
- Grounded in modern sport-nutrition literature
Tool 03
Hyrox carb loading
