Walking to work is an easy way to hit my step goal before lunch. It's 6.75 km and 8,500 steps. At just over an hour, it takes only about 20 minutes longer than the bus or 30 minutes longer than the train.
The problem is the dewpoint. When I left my house, the temperature was a delightful 19°C...and the dewpoint was a sticky 17°C. By the time I'd gone ten blocks I was already uncomfortable.
Note to self: bring a fresh shirt when you walk to work, no matter what the weather looks like.
