Thanks for the input John! That was my first thought some months ago; call it whatever as long as I'm having fun!
Art; you are right-on with my observations lately. It seems to me that speedhiking involves some type of contest.
In mid of 2007, speedhiking was declared a sport by the New York Times and shortly thereafter (Aug), the first race worth 25 grand (16 miles) was held at the Sugarbush Resort in Warren, Vt.
While researching for light boots, I have seen that Merrell and Mammut have introduced boots for speedhiking and fastpacking; thus, drawing a difference.
As Art stated, fastpacking have beed defined as "running multiple days on the trail while carrying a pack with food and tent." —Ad Crable, "Running wild," Lancaster New Era, June 18, 1993.
I admire speedhikers and do follow/monitor their reports when available. There is plenty to learn from them. I do have more of a fastpacker attitude. I have a 42 mile fastpack hike coming up in Aug1 out in the eastern Sierras. Although I plan to be done in about 18 hours, I am taking enough gear to be able to change my mind in a moment's notice if I so desire (or need to!) and make it a three day hiking trip; that, I think, is an essential characteristic of a fastpacker -- flexibility.
