The introduction of Route Achievements on Zwift seems to be a success. A lot of people like to have goals to chase and the beauty of these achievements is that you can work them into your regular training.
So why do runners only have 10 of them, for the running-only routes in Watopia and New York? I mean, sure, some of the cycling routes are very long, but a lot of them would be perfectly reasonable for most runners to complete, and honestly some runners would probably complete them all just for the extreme challenge. Why not make all route achievements available to runners as well?
