Hourly Weather Hourly Point Weather forecast is a site I use almost everyday. I can't stand running in cold weather, so I try to plan my afternoon runs for the warmest part of the day. This site lets you factor in wind-chill and cloud cover, which makes a big difference when you're out in the elements. gmap-pedometer.com is another useful site that will let you map a route for distance and elevation.

Anyone else have other links to useful running tools?
