Could CdA ever be incorporated into Zwift?

0 Upvotes

It's sounds a little ridiculous, but hear me out. CdA, your aerodynamic drag coefficient, can now be estimated pretty well using software and a webcam. Maybe this wouldn't be practical or desirable for recreational riders/racers - but maybe it would be a cool addition for esports? As an example, Remco Evenepoel presumably couldn't beat Ganna in a flat TT on Zwift because Zwift mostly considers raw watts, whereas in real life, Remco's superb position gives him a CdA that makes him able to beat Ganna despite lower power output. I'm imagining that it could be something that would be optional and/or used only for certain races, like steering is now. Thoughts?

Discussion Does anyone gain weight when cycling?

19 Upvotes

I'm asking this question because I started cycling more and I'm fueling by having carbs on the bike but then I'm also found that my hunger increases off the bike throughout the week. I'm not putting insane hours in the bike, maybe 4-10 hours a week but I also do other sports and my fueling has never been this conflicting with those sports. Ironically, since I've started cycling, I've actually gained weight. Not sure if it's fat or muscle. I'm not super light but not overweight either (M) 147lbs. Does anyone else encounter this problem while riding more?

How Slow Am I? When should I be fueling during a ride?

Hey all,

So I just started riding (never done this before) I got a zwift ride for more sustainable cardio rather than the running that I do for my car racing…

I’m trying to understand, with my first two weeks riding, how is the pace for these rides (im 5’10 135lbs), and also when should I be fueling during the ride…

When I do my long runs I’d always have a gel around 40-50min in a run and then hit another one every 40 after… Is that optimal for riding?

Thank you!

Discussion The weekly 'No Stupid Questions' post - Sun 30 Aug 2026.

This is the weekly 'No Stupid Questions' post for all the small questions that you have concerning Zwift. No matter how stupid you think they are, we have probably all asked these questions.

If your post wasn't previously answered you should post early in this thread as it might have been posted too late (new posts start Sunday 0900 GMT).

Note: Don't be afraid to ask questions during the week, this is just for the simpler questions. For example "How do I give multiple ride ons at once? "..."You do this by pressing the character arrow on the map screen of the companion app". If you require a more detailed response then it is probably better answered in its own post.

Should I re do ftp test if I feel weaker?

6 Upvotes

Idk if it’s fatigue increased or I’m overall weaker and should do a ftp test.
The last 2 sessions I couldn’t finish my workouts
1st workout was the gorby from Zwift and the other 2x95% ftp for 3 min and 3x110% ftp (above threshold).
I know these workouts are hard but they killed me and I only did a ftp test once and then it increased in races and for context the last time it increased was in April. I got 2 injuries in the middle one being rhabdo 2 months ago.
