RaceOS Turns Triathlon Week Into a Solvable Spreadsheet

Editorial interest 82/100 Selection signal · not a rating of the site

A race-planning tool that derives pacing, fuelling, cut-off margins, and five-bag packing lists from a specific course and goal time.

Landing page captured for the 2026-09-02 issue.

Field notes

The displayed workflow connects a target finish time to discipline splits, transitions, projected cut-off margins, nutrition, hydration, and transition-bag contents. Its example works at race-week granularity: 78 g of carbohydrate per hour is compared with a 90 g gut ceiling, while aid stations at bike kilometres 34 and 92 explain why a particular bag carries a particular load. The page also shows a five-bag structure and a sample 11:45 finish against a 16:00 final cut-off.
