A unique wedding invitation

I was asked by a friend to design a wedding invitation for his friends, both runners, who were to tie knots, so to speak, this August. Yeah they already have a design in mind and I was asked to improve on it.

A runner's bib. On paper.

It's simplicity is quite a challenge, actually. What should be on a runner's bib (some call it race bib)? So we agree on this design and went on with the printing.

Runner friends are now having their invites.
