I find it really interesting that I'm included in that, but I think I understand why.

I absolutely share your intimidation by really outdoorsy-oriented profiles. It makes me feel like the person would always want to be off doing things I didn't know how to do, wasn't fit enough for, or just wasn't interested in.

I don't place my mentions of cyclling in that category, for two reasons:

1) Bicycling as a primary mode of transportation is common among people my age in my city. Cycling isn't a hobby for me; my bike is my car. I rarely ride just for pleasure.

2) Because of the first point, dating another cyclist--or at least a bike-friendly person--is actually a practical matter for me. If I date someone who has a car and no bike, and we travel together, I'm relying on that person for transportation wherever we go, and cannot leave by myself if I want to. This is inconvenient at best, and potentially scary at worst. We could travel separately, but drastically different speeds make that a bit of a nuisance ... plus, traveling with my date is just nicer.

This is not to say that I wouldn't date someone who didn't use bikes for transportation. But it's easier, and if it's going to be an issue I'd like to establish that up front.

Besides ... it's a filter for the sorts of people who might think "Ugh, why are these stupid bicyclists riding in the road?! Don't they know it's just for cars?!" ;)
