This is the result from this lesson. It’s a pace calculator in metric units, with a simple validation for the entry of non numbers into the input fields.

This lesson was largely a review for me - the vast majority of the js work I’ve done up to this point in my career has been to manipulate the DOM using jQuery, so this came rather intuitively.
