pace calculator

What do you mean, by not big enough? Seems to be pretty normal to me, but if you want to adjust the size, hold the Ctrl key, and scroll the mouse wheel. If you use a browser on a phone or a tablet, zoom up with two fingers.

If it does not look like on the screenshot below, then please post a screenshot too:

Your screen is too small and/or the resolution is too low. You can use the zoom function in the browser to make everything smaller. Then you will see the pace calculator.

You can also open a browser in full screen mode - by F11 key.

It hides browser's menu / bars, so a little more space for a website.

F11 works! thank you
