In the evenings, usually every day. However starting out, it was more like every second or third day, until the feet became stronger and I had learned gradually to run with more finesse, exact landing, and less peak impact with each stride.

When I go out to run, there's no set goal or any pressure. I have a route in mind, but the idea is to just take it easy and bounce along at whatever speed I feel like going. It's like when I used to cross-country ski just for fun.
