ask.com unveiled its new interface this week. I played around with the maps feature and found it to be immensely better than any of the current offerings out there. You can put in a start point and add as many destinations as you want. But, that's not the best part. The most compelling feature, in my opinion, was the ability to drag and drop the pins that represent the destinations. You can drop it anywhere on the map and it will automatically calculate the new coordinates for you.
This is exactly what I'd been wanting for a long time. In the past, when I would want to map out a route using web-based maps, I had to put in the street intersections for pairs of starting and ending points and do that for all the segments that made up my intended route and finally add up all the distances to get my final mileage. Needless to say, it was a tedious task that required quite a bit of time. This makes it really easy. Very impressive.
I don't expect it will be as accurate (down to the decimal) as using a bike odometer. Nevertheless, it could be a good tool to get a general idea of how long a route is.
Off to find a few new routes to go running.
