When searching for races I’d like to filter by distance. There are a lot of races <20km but I prefer >20km races. Showing the number of laps isn’t always helpful if I don’t know how long each lap is
Zwifthacks is a very comprehensive search facility.
An alternative, not providing quite as many search options, is ZwiftPower, which I notice you have signed up to.
Under Events tab
Choose Filter option.
Select distance option you want (probably 40km which gives you 30-40km races)
Thanks for the suggestions.
