What's your top speed?

+1 When I started to get fairly fast I would blast it everywhere and knacker myself out and probably be about 2 minutes quicker. Since then I try to flow through junctions, timing traffic lights and roundabouts.

On a similar vein, I had an off last year and took things easy for a while after a) to protect a sprained wrist and b) to regain my bottle. I did notice however that my average speed on a decent run stayed the same despite the slower riding.
