Here’s a summary of notable multi-day action:
Well known ultra/adventure runners Charlie Engle and Marshall Ulrich announced plans last winter to set a new record running across the US. They had major funding, publicity, and an extremely ambitious plan: 70 miles per day.
Their May 24 start date came and went and I didn’t hear anything. A recent web search disclosed that they apparently have made the project even larger, by combining it with a National Geographic documentary, and the run appears to be still on for Aug 8.
Other than that website I know nothing; if anyone does, please post a Comment.
CONTINENTAL DIVIDE TRAIL RECORD ATTEMPT
An even better known ultra runner (one of the best actually), David Horton, set out on June 7 to set a new record on the CDT. This had obvious appeal, as David is the current supported record holder on the PCT as well as the previous speed record holder on the Appalachian Trail. The CDT would complete his Triple Crown of long trails. The plan was to cover the estimated 2,959 miles in 69 days (42.9 mpd).
However, the CDT was not to be. The effort was abandoned at the end of the first day due to dehydration and exhaustion. Yikes.
APPALACHIAN TRAIL RECORD ATTEMPT
Starting on August 5, Karl Meltzer will attempt to do the 2,175 mile Appalachian Trail in less than 47 days (46.25 mpd). Like David before him, Karl is one of the best-known and accomplished ultrarunners in the country. It’s gonna be good.
This blog will have more updates and a live “chat” with Karl in mid July. In the meantime, there is excellent info here, including interviews with David, Flyin’ Brian, and Trail Dog: http://www.mountainrunning.com/
