The first of the VTTA Zwift time trial series was preceded by a 'test event' that I missed. So I came at it a bit cold, not having done a Zwift TT in nearly a year. The TT was on the nearly pan-flat Tempus Fugit course. This is really quite unrealistic as even on the flattest real life courses there are minor undulations and variations in wind resistance that make the ride a bit more variable than in a virtual world like Zwift.
Anyway, I made the most stupid error (especially given the decades of TT experience I have), and shot off at the start at a completely unsustainably power. Subsequently I was all over the place power-wise and faded really badly towards the end. I could see my average power dropping...I finished in 24:20 (I think), with an average power of 232W. Apparently this was good enough for 7th place on Age Adjusted Time (so I am told). Maybe the re weren't many VTTA members taking part!
In last year's series, I gradually improved my average power through the series. Maybe that'll happen again this year!
