Put these calculators on your own site
Free for running blogs, clubs, coaches and race sites. Copy a snippet, paste it into your page, done. No sign-up, no cookies, nothing you or your visitors type leaves the page.
How it works
Each snippet adds the calculator in a frame and a line that credits UltraCalcPal and links to the tool. Please keep that line: it is the only price. The frame resizes itself when the script loads, and works without the script too.

Is it really free?
Yes. There is no limit, no account and no ad. The only thing we ask is that the credit line stays under the calculator.
Does it track my visitors?
No. The calculators run on the visitor's device, set no cookies and send nothing anywhere.
Can I change how it looks?
The width follows its container. The colours follow UltraCalcPal's design, so the calculator looks the same on every site.
Can I use it in WordPress?
Yes. Add a Custom HTML block and paste the snippet.
