I did 18 miles this morning - my longest ride so far, and on a lovely route to work. I live about 5 miles away from work, so I did a big loop away from the city along country lanes, then headed back into town for the last few miles. It was so peaceful out there at 6am!
I've actually commuted to work on the bike every day this week and covered somewhere approaching 75 or 80 miles which is a lot more than normal (my car is broken down and the weather's been nice so I've used the bike for everything) and bought myself some pannier bags as a reward, it's so nice to be able to cycle without getting a sweaty back or sore shoulders from my rucksack!
