I started running for the first time in years and years last December, and then ran a 10K event in mid-January.
I actually enjoyed it! I get more of a "high" when I run than when I cycle.
But then I switched my focus back to cycling again.
When Rowan had his accident, I started running again because I found it good stress relief, and signed up for a 5K. Unfortunately the 5K was postponed until the end of September because a massive storm washed away a lot of the route.
Right about that time, I started experiencing more arthritis pain than usual in my feet, so I'm seeing a podiatrist now, and hoping to be able to start running again in time to do the 5K at the end of September.
