Sadly, this is a question that only a minority cres about, but there are always chances that someone may know.
I'm fond in iWeb and my Nike+ running kit too.
Nike+ has released a new function that allows workout graphs to be published in myspace, blogs, web ites, etc. This is based on Flash, the function provides the flash animation code for your site, I think. However, it doesn't work in iWeb.
Any ideas?
Thanks
