My potential GC battle in C category turned out to be a damp squib in the end.
The guy who I was three seconds behind was certainly in the pens (I saw his name and avatar behind me), but when the event started, he didn't. Either he got a mechanical/technical problem or he was called away from his bike and did not come back in time for the start time. All I know is that his avatar never actually crossed the official start line outside the pens, because he didn't show up on ZwiftPower LIVE at any point.
Of course I didn't know that immediately and still sprung out of the traps at high pace thinking I needed to get a big lead over him, but by the time I was halfway round the flat part and hadn't seen his name appear in the right hand side I thought something must be up. So I spent the next few minutes scrolling up and down on the companion app on my phone to see if I could see him (which may have meant a small drop in my watts as my concentration lapsed) and when he wasn't showing up, I just then tried to put in a steady effort all the way to the finish. Struggled a bit on the climb, but still got a PR, so it wasn't like I was slacking or anything.
Think I'll come 8th overall in GC, as the person who had the lead (who only inherited it after last week's race) did a stupid thing and got promoted to B after a hard race at the weekend, thereby throwing away a potential win!
Well done Steve
