Welcome to the F501Ultra,

We all know about the Festive 500, riding 500km between Christmas and New Years eve.
In the spirit of this challenge we came up with this ultra event. We have seen 500km "parties" on Zwift last years, but with large groups.

This event is different, this is a solo ultrarace.



December 28th 9am CET
