• Something has gotta be up with either my set-up or Zwift is full of shit. I did a "race" today and it said avg speed was 28mph. My trad / dumb turbo setup is an Elite trainer with cadence and speed (set on 3) on a 48x16 track bike. Even when I was in OK shape attempting C races at herne hill I dont think races ever got that fast, no way I could have done 10 miles at this pace.

    So is it known dumb trainers are a great way to sandbag? Or is it that zwift races are so far beyond reality as to be silly? I understand the basic watts calculation on smart trainers appears accurate tho.

    Yes @BareNecessities indeed I am going through a strange time, as we all are

  • Are you using a power meter or just a speed/cadence sensor and letting zpower work it out? If it's the latter then it can wildly over-estimate how much power you're putting out. Before I got my PM I used zpower to measure my FTP and it came out as 320W or something, my real FTP when I retested with a power meter was ~240W.

  • You had me at

    Zwift is full of shit

  • Speed/distance bares absolutely no relation to real life, so just ignore it. It simply doesn’t matter.

    I often do steady 10ok group z2 rides on zwift at an average of 44kmph. It’s obviously not realistic to think I’ve ridden anything like a real 100k. I just think of it in terms of time in zone.

  • is it known dumb trainers are a great way to sandbag?

    Yeah, that's why many races limit published results to people in ZwiftPower and/or with HRMs to show the data isn't bollocks.

    ie. here's a rule snippet from a race tonight:

    RULES:

    • Heart rate monitors and Cadence compulsory for all categories
    • Power Meter and/or Smart Trainers needed; using zPower will be DQ
    • Choosing lower category than ZwiftPower says will cause DQ
    • Riding outside chosen category (95% of CP20) will cause DQ
    • Riding very unrealistically or cheating may be DQ as well

    More race details, full rules and final results, based on your category (separated for wo/men), may be found on https://www.zwiftpower.com/league.php?id=211. Remember you need to have a registered account with Zwiftpower.com and accepted their terms and conditions to be in the results of the race. Please also maintain an open Strava profile to facilitate organiser inquiry.
