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!
