There's probably a really interesting discussion there about identity. I still sort of struggle to identify as a runner. I'm just someone who runs. I don't have a 26.2 sticker on my car, but I do have a 46er sticker.
There's a run-bike-run duathlon here in a couple weeks. While I have no identity with duathlons, I'm intrigued. It's 2-25.3-2. I have a nice but not pro or tri bike, and I've never done a transition.
