I deleted the question for two reasons:
Its trying to compose a list, worse its asking for a list of favorite ways to find new routes. The Not Constructive close reason description reads:
This question is not a good fit to our Q&A format. We expect answers to generally involve facts, references, or specific expertise; this question will likely solicit opinion, debate, arguments, polling or extended discussion.
So instead of deleting it, I could have closed it instead, but closing could and probably should eventually lead to deletion, unless it serves as an example of questions we don't want. The reason we normally first close, wait and only then delete is so users can raise objections, edit the question to make it more constructive and have it reopened. So to do you a favor and give you a chance to fix it, I've undeleted and only closed it.
The second reason I deleted/closed it is that, in my not so humble opinion, this wasn't an example of questions we should be wanting on our site. While the first two answers (including yours) are mildly useful, the other answers were one-liners referring to some website, links to social services such as Runkeeper or simply not useful.
When I came upon this question last week I asked myself the question: does this question make a new visitor coming in from Google happy? Would that visitor, based on the quality of the question and answers, think to himself: "Geeh, this is a nice website, I think I'll browse around and see if they have more useful content." I believe the answer to that is a firm no. That's not to say a similar question, that's more focused couldn't be, just that this incarnation of the question is a bad one.
Because the question is undeleted, but closed now, you do have a chance to 'fix' the question. However, given are relatively small community of active users, most old questions are dead questions. Editing it would bring it back to the front page and might encourage someone to answer it in a better way, but its quite unlikely. Still, another problem is that making the question less broad (I mean, finding running routes all over the world? That's a bit broad isn't it?) would either invalidate a lot of answers, which would have to be updated (not going to happen) or deleted (already done in some cases).
This is related to a bigger issue, which Greg also tried raising on chat, people don't downvote enough. Heck, I'm guilty of it myself! The result is that unless a question get's a decent amount of views, there's barely a distinction between bad answers and good answers. Worse, because some answers don't get downvoted, those users might think there's nothing wrong with their answer and they keep posting similar answers (For example, users who continuously post one-liners that should have been comments or links as answers).
So honestly, I don't think this particular question was worth the trouble of saving. I'd rather encourage you to ask a new question, that's more focused and doesn't attract the same answers as the original did and we all just forget about this one. I'm sorry that it cost you rep in the process, but I think its for a greater good.
