How about on the first weekend of May having an Everesting event? Have a few different start times for everyone and have everyone climbing Alpe du Zwift. Maybe go for a record for the number of people Everesting in one day. There would be plenty of support for everyone. Next year it could move to Box Hill and then the following year to Innsbruck.
I wish for this, we could use the route builder, like how the workout builder is used to plot out all the u-turnes so you can just ride and not have to worry about remembering to u-turn. The route builder feature would work just like the workout builder except with picking turns. This would be awesome at building meet-up courses specific to you and in this case, we could build Everesting courses for each major climb in Zwift and not worry about missing a turn.
