on group ride pretty much the same , if you can find and hour climb or a climbing road race that seeing you have to produce more than 300 up the climbs you might average it , indoors it should be pretty easy depending on how accurate your power meter is , it will be about 25 miles per hour .
if you are talking 325 for like 5 hours then i will be unable to understand how thats possible but its said to be done by the elites !
