RunSignUp has the ability to search for your photos by Bib# or Name. Try it, it’s easy.

The photos can also be found by going to your results page on RSU, and clicking on the small photo icon under your name.

The bib# tagging is done automatically by google software and is not always perfect. It is being worked on by RSU, to make it better. You can also manually add missing bib#’s yourself, so don’t hesitate to help when the software missed it!
