Race nutrition calculator

Pick your race, enter its legs, say what race day will be like and a little about yourself, and your targets appear — what to eat, drink and carry, and which bag it rides in.

Race information stays in your browser unless you press Save this race, which sends the race — its name, the organisation putting it on, the year, the length class and the legs, and nothing about you — to our server so other racers can pick it. Pressing it also loads Cloudflare Turnstile, a captcha that looks at signals from your browser to check you are a person; it is loaded at that moment and not before. Opening a link to a saved race makes one request to our server carrying only that race's public identifier. When shared fuel catalogue access is enabled, typing two or more characters in a new fuel item’s name or brand sends only that product query to search for existing items. Saving a new fuel item sends its product details and a fresh captcha token for review, without race or personal details. Your complete local fuel list is never uploaded.
