ENDURANCE FUEL

Carb planner for any endurance session

Session data — export or import your library
Edits and custom products only last for this browser session. Export before you close the tab, and paste your list back in next time to pick up where you left off.
Next up: caffeine totals per hour with a sensible cap warning, and sodium/electrolyte totals against sweat-rate guidance. Every product already carries fields for both, so it'll drop straight in.
