The time and difficulty filters on the Zwift Events page are very useful, but it still takes a lot of scrolling and reading to find an event you want to try.
A couple of suggestions:
Add a filter for Event Type: Race, Group Ride, Group Workout, etc. This would be a huge help.
If a filter is not practical, then use color or some other formatting to identify the type of event.
Condense the web page format so there are more events per page. An alternative would be downloadable event list in a table format(Excel?) that could then be sorted.
