Don't worry. I'm not doing any work.
I came down to the office to see how far it is from home on the bike. It's two and three quarter miles; approx 15 minutes riding, accounting for traffic lights, chains coming off and saddle-soreness.
I shall be returning to the office later in the afternoon to do some more non-working. At the moment, I'm on the outside of a can of diet coke and I'm debating which route to take to leave this place. Sadly they're all uphill!
So far so good. I can still move and breathe. Having said that, most of the downhill riding only involves holding onto the bike.
