Ok did a quick workout on MYWhoosh this morning, for comparison I use a KickR and Stages HR monitor, linked to an i7 @2.1Ghz, SSD, 16GB ram,X64 running windows 11 or 9th Gen iPad ruining A13 Bionic chip, as zwift hates my laptop also
@HarryTheDog , needed 16gig of space to run on the IPad but didn't want to delete all my daughters games so didn't try it.
All paired up with windows quickly, into the menu trying to find a MyBunch ride at my speed, these as you know run 24/7 on zwift and you can join as you want and do the miles you want at the advertised pace, not on MyWhoosh, they start at set times and nothing else so a solo ride it was.
Now I consider my laptop to be OK , its sits right in the middle of the required spec, but to get some smooth rolling graphics akin to Zwift i had to lower the graphics settings. The ride was good and I feel the statistics , HR ,power, speed , cadaence etc;, are a lot closer to the real world, in Zwift i can roll around with a bot pacer at 20mph, here i only reached that speed when I could find someone to draft, and there was quite a few on there. The inclines felt a lot harder than Zwift and at the end I was more knackered than a similar Zwift ride, and my average speed was down to normal road/real world speeds,
So its free , I would say more real world results than Zwift, its free, but the space, 16 gig, the lack of choices and the graphics let it down, but they can be improved , and its free.
