It's been about 10 years since I last rode on a bike. My wife and I have decided that we need to get ourselves into shape, and one method we've decided on, encouraged by our daughter, is to bike back and forth to work.

According to Google Maps, I have approximately 10 km commute each way. This will take place in the morning (generally 7:30 AM start, but sometimes earlier) and the afternoon/evening (generally 3:30 finish, but sometimes later).

I already have my helmet and lights. What other accessories are recommended? Also, what kind of training should I look at before I go with the full daily commute?
