We originally built this system (in a very rudimentary way) to support a web development client's need for a way to display athlete PRs on their site. It was unwieldy and inelegant and a pain to keep updated, but it was better than manually keeping track of a plain HTML list on the site. So we sat down and figured out a better way that was not only easier to use, but better looking and scalable to multiple sites.
Looking forward, we will be adding additional movements and WODs, including more CrossFit Hero and CrossFit Women WODs, as well as CrossFit Open workouts. Additionally, we're working on a couple of add-ons, including a WordPress plugin that will simplify adding leaderboards to your WordPress site, and one-time-use competition leaderboards. Stay tuned, and give us a shout if you have questions or comments.
