Even when I was working in an office I would sometimes take 2 to 3hours bicycle rides at lunch time because it was the best moment to be doing sport outdoors in winter.

I would just make sure I had no scheduled meeting and had people in my team available. Sometimes I would do it to make up for extra time outside of office hours. This also allowed some of my coworkers to leave earlier because they knew I would stay longer to do my regular shift.
