Hi, I have noticed when joining group rides that sometimes I am having to put in almost double the effort when in the middle of the group, one minute i’m riding with the group fine the next I drop back and have to push real hard to come back! I thought this would only be the case if i was dropped off the back as the drafting effect would go but this is in the middle of everyone too? Also when i look at my w.kg compared to nearby riders mine would be at say 5 or higher where as all other riders would be say around 2.5 - 3 yet be at the same speed?
Is there a reason i’m having to push so hard for the same effort as everyone else? My trainer is the Tacx Vortex smart btw, i thought this was a very good trainer for Zwift!
