Feature Requests: More descriptive names for walks/runs or better search

I just started here and it seems that it is really hard to find walks that others have created for large cities.  For example, I live in Houston, TX and when I did a search I got something like 1900 returns, and all of them have descriptions like Near My Home or 3 miles.  If everyone wrote a really good description for their route it would be nice - but if you asked for a name and a description it might help.

Either that or narrow down the search so that when I put my zip code I don't get a gazillion hits and some of them are 20 miles away.  If you could have a drop-down and have the choice to search within 1, 5, 10, 20 and 50 miles would be great.
