Downhill should be relooked into. Got dropped yesterday in the Vatternrunden, when exiting the new dessert section. Was at the back of the pack of about 33 riders, just briefly lost connection with the pack (due to I was not paying attention), and got dropped. A long 400 watt efforts did not got me back, so I road the next 60 km solo at 3,8 watts/kg. Looking only at the watts/kg results at the finish leaderboard, I should up ended 3rd or 4th. But now I got stuppely dropped into 33th place, in a way that has nothing to do with cycling. Putted beast-mode on and battle me into a 10th place overall.
The Zwift engine for downhill should be modified. For exemple, downhill the Epic climb, or tower climb. When you go downhill at 60km/h, 300watts or 400 watts is not going to add some extra speed. Mayby 400 does a tiny bit, but 300 not. Going +70km/h … doing 400w … does not give you extra speed.
