I had reasonable hopes for this event - it's a nice DC course with a smooth turn at the Cambridge end. I travelled out with Katja, who's start was (as I recall) about 4 minutes after me. It was fairly breezy  on the day. In fact, when I went out to warm up it was obviously going to be quite hard on the return leg. Based in Cambourne, the F2D/10 starts on a minor road, but soon makes a sharp left turn at a roundabout to go down the slip road on the A428 in the Cambridge direction. There was a rather neat tailwind for much of the outbound leg, and it was good riding, with not too much traffic. Until, that is, when an enormous honking startled me just as I entered the slip road for the turn. It quickly became apparent that this was emanating from a correspondingly enormous truck, which came up the sliproad past me, though giving me plenty of space. Worryingly, it was followed by a line of at least 6 cars, and I feared I'd get held up at the turn. The turn is quite fast, with gentle and well-cambered curving turn to a roundabout - when I approached the roundabout, the entire train of traffic was in the left hand Cambridge-bound lane, and I had a clear run through to make my turn. As feared, the stiff headwind on return leg made things a bit difficult! On some of the rises, I was embarrassingly slow. I just grit my teeth and pressed on as best I could. The exit from the DC to finish is often a bit troublesome with traffic at the roundabout - today I had not real issues, and stamped on the pedals to record 22:32, about what I'd expect for the course and conditions.
