To become a better runner is not only about how often or how long you run. It is important to give the ‘running’ muscles and joints a rest by doing a different aerobic activity – walking, cycling and swimming are all good alternatives.
I walk to and from work every day and try to include a session on elliptical trainer or a bike once a week as well as a dip in the pool. Swimming is my personal favourite, I just wish it was possible for me to swim outside rather than in a pool; I do feel like a wet hamster after a while. My front crawl is rapidly improving though 🙂
