I love it.I've lost 22kilos doing it and thoroughly recommend it if your running days are over.Few more kilos (I joined weight watchers to shed the remaining weight more quickly) and I'll be a very good A rider.Hope to see you there. Zwift allows you connect a bicycle via turbo trainer to a virtual world of 1000s of other cyclists and runners too via enabled treadmills.
It's just how it's been popularized.When I get the weight off I'll be 4.6w/kg and since I only trained for six months I'd expect that (hope it) would increase to 4.8. 5 is domestic pro level on zwift and you have to provide proof of real world performance at that level.
Bought a last year's caad12 105 disc on sale which will do me until dotage.Lots of races/TTs on british cycling/ctt/vtta etc.Hope to compete in 20 events this year but it will probably be ten?On course to lose the weight by march then a month for hormones and strength to return and God willing racing starts.
