Huh???
Non weight doped Zwift is like doping all the small riders on the flats and downhills, because they have an advantage even there which is unrealistic.
I therefore don’t blame big riders for setting their weight low. In the real world, small riders have an advantage naturally like a tall basketball player, but it is only on uphills.
I am riding on zwiftpower. It’s a group race of various distances and a range if flat and hilly. Groups are divided from a to d. All based on wpk. If you exceed the range you are bumped up. So we have guys with good of 325, who don’t want to ride a, who bump their weight up to 120kgs who win the D race with a wpk of 2.4. Usually just flat races, as weight has way less impact on the flat.
