I was thinking about this yesterday, as I was running my 5k for B210K wk 2 run 3. I still very much say and think in terms of "I love running", or "I go out for a run." or "I need to go and run even though I want to stay in bed."
I do not describe myself as a runner. I think I'm still pretty bemused that I actually want to go out for a run, that I'm beginning to plan my weeks around runs and the park run, (I've even arranged a holiday at home, so that I can go to their 100th park run!) that I'm looking for forest trails to run in.
I wonder how long it will take for the verb to become a noun?!
