Zwift does not have wind and it compare very well with IRL when it is a windless day. Comparing apples and apples.
Feature requestā¦ add random wind and put a windvane indicator in the HUDā¦ I think the golf simulator games have this.
A few weeks back I was riding with Maria in Makuri and was at one point not paying enough attention and therefore got dropped. As an heavier rider than Maria 94kg vs 75kg I was doing almost 10 minutes around 3,0 to 3,5 w/kg and Maria only was riding further and further away at a 2,2 w/kg (165 watt) from me. How is this possible as I was doing way more w/kg and way more raw power than the Maria group and only lost more distance to the group.
BTW I was riding with another rider in the beginning trying to catch up.
u can catch up to coco with that pace easily.
were u riding a TT bike or something?
Iād say Zwift has it about right. If youāre chasing a group (pretty much always the case) thereās a leader pulling everyone else. Itās hard to track because the leaders rotate pulling. That 4-5 wkg number is in there while several other riders behind them are at 2.5-3.5.
My experience is a gap of 4+ seconds is almost impossible to overcome.
Wind would be a fun Zwift feature, but itās a non-issue as it would affect everyone equally (plus, people would hate it).

Watts and Watts/Kg is totally different on flat groundā¦the W/KG displayed isnāt the important figure as already mentionedā¦ would be cool if it displayed w/kg on inclines and on flat just power.
whos going fasterā¦
80cm 67kg rider at 4w/kg (oooh strong) ā¦(268w)
80cm 90kg rider at 3w/kg (1w less, must be slower?) ā¦(270w)
the lower w/kg rider is putting out more Power, and would be going faster or similar.
HOWEVER, How zwift deals with wind resistance of two equal height riders of different weightā¦?! that I donāt know. but would assume they would increase frontal area of a 2nd riderā¦ thus making them slower a bit.
With only 2w more than the 67kg rider I would say the 90kg rider will go a lot slower because the rolling resistance is a function of weight.

Yeah I missed that aspect of it, however doing a quick test of bike speed calculator online shows a 67 and 90kg rider going 270w on 0% gradeā¦
90kg: 35 kph
67kg: 35.6 kph
not as significant as maybe I would have thought after missing it (or as noted by āa lotā), and with just 12w more power needed to overcome the weight at those watts and weights.
I would assume when they are mentioning catching a pack, they are watching the lead rider and all riders to see if someone is āpullingā at the front at harder then the rear drafting riders. Also based on my limited zwifting experience (low race count and lvl28)ā¦ not many people put in work on the front to push a groups pace, mostly just a through and off rotation at almost all the same effortā¦ so easy to gauge a pack ahead. Most group events I have been in lately people are not even doing a 5-10sec push when they find themselves on the front.
