The weekly challenges provide such a rich resource for strengthening your Alteryx abilities but for new uses a lot of time is spent merely collecting the older challenges to work on them. I would suggest creating a page with all of the start files, and a page with all of the solution files so that all of the challenges can be downloaded from a single location. This would also provide an opportunity for a new weekly challenge to build a workflow that downloads challenges within a specified range, create windows folders for each week, and cleanse the pesky underscores from the front and end of many of the files.
