I just finished a 17.766km cycle that lasted about 0hh:36mm:6ss !
Yesterday was one of the hottest days in the UK so far, but it cooled down a fair bit in the evening so I spent about 30 minutes exploring a route on the 'Watopia' world. Was good fun and I definitely enjoyed the ability to just put music in and just be in the zone. It was a lot easier to push out watts when you're also not having to contend with poor road surfaces, traffic/cars and other road obstacles, and I'm definitely already a big fan of Zwift and turbo training riding. My brother did say that it was slightly odd to purchase a turbo trainer and start Zwift riding when it's the Summer and pleasurable to ride outside, but I'll be doing a mixture of both normal cycling and zwift riding in the immediate future.
I've signed up to ride a entry-level race in a couple of hours; I think it's about 16km around the Richmond UCI World Championship route, so will be a nice test to see what I can average over the distance. I'm going to aim to try and keep my watts above 200 for the entire race, but I think it's a little ambitious so will have to see if I'm capable.
