What you type stays on your device

All calculations, tables and PDFs are made in your browser. Times, distances and goals are not sent to us or anyone else. We have no accounts, no forms and no newsletter.

Your unit choice

If you switch between km and miles, the choice is saved in your browser’s local storage (key rp-unit) so the tools open in the same unit next time. It is not sent anywhere. You can delete it by clearing site data in your browser.

Cookies and statistics

We do not set cookies. We may count page views with Cloudflare Web Analytics, which works without cookies and does not build a profile of you. The site is hosted by Cloudflare, which processes technical data such as IP addresses to deliver the pages and protect them from abuse.

Ads

The site has no ads today. If that changes, we will update this page first.
