RCP, it will be like taking a screenshot of whatever is viewable on the website at the time you press the button.

In terms of changing the date, venue and race number that is something you'll have to do within the script (macro) at the moment, however it should be possible to make it so you can put these details into cells within the spreadsheet, hit the button and it will update without actually having to go within the script and risk disrupting anything.

Let me see what I can come up with and i'll post a bit later. In theory it shouldn't be too difficult but computers find a way of never making things that easy.
