Share your pace — and a lot more

A share button on every page, link previews that work, one clean time format everywhere, and activities that trust their own GPS file.

Three releases went out today. Here is what you will notice.

Share it

Running is a group activity even when you run alone. Someone in the club chat asks what 4:30/km is in miles; someone else wants to know what their half marathon says about their marathon. Until today, that meant a screenshot.

There is now a share button on every public page — every calculator and guide, the race calendar, world records, and public athlete and activity pages. On a phone it opens your normal share sheet. What travels with the link is the actual answer, not just a URL: "Pace for 10 km: 5:00 min/km — calculated on Calcpace", in whichever of the fifteen languages you are reading.

Share one of your own runs and the link is always the public one, never your private address. A run you mark public is reachable on its own link even while your profile stays private — sharing one run no longer opens your whole log.

Paste a Calcpace link anywhere and it unfurls with a title, a description and a proper preview card instead of a bare URL. The front page also stopped promising "precision-backed tools" and started saying what makes this site different: a 5:30/km in 30°C heat is not the same run as a 5:30 on a cool morning.

One format, everywhere

This morning world records still read 03:51, the calculator headlined "Pace 00:05:00 min/km", and an activity page wrote the same hour two ways — 1:06:03 in the header, 66:03 in the splits table below it. Every pace and duration now reads the same way: 3:51, 5:00, 1:06:03. That started one level down, in calcpace v1.14, the open-source library this site's arithmetic runs on. A real bug came out with it: mile splits reported kilometres under an mi header, overstating every one by 61%.

Your GPS file wins

Editing an activity after uploading a GPX used to overwrite the distance and duration read from the file, while the splits below still came from it — one page claiming 10.0 km above a table that ended at 3.57 km. Distance, elevation and duration are now read-only while a file is attached. To correct them by hand, remove the file. The map also stays under the navigation bar when you scroll.

And this page

Every page that ends in a short FAQ now publishes those answers as structured data too, so a search engine reads exactly what you read.

And this section is new. From here on, changes get written up here — dated, in plain language, for runners. In English only: a dated note goes stale too fast to translate fifteen ways. There is an RSS feed if you would rather not check.
