A Zwift one of course - have you seen the weather? A 17.5km flat. It was a mixed category race, so I was towards the back obviously. Riding at a steady power, in a small group of two or three. As we edged around the course we collected in a few riders to find ourselves in a group of eight with 5k to go. I decided to have a go for a break rather than wait on a sprint. With 2.5km, on a short incline, I went for it. A couple came with me. I kept the hammer down. My heart rate was up at 171-172 and I dropped them on the next little bump, continuing to keep the power going. It was like a 4min time trial effort on the edge. The group never fell totally by the wayside, so I had to keep the effort going all the way to the line. Haven't worked that hard for a while...
