I've heard that a lot fo people don't complete the full thru hike in one season for various reasons.

We're (the 4 of us) an experienced and hardened group of kids, looking to complete a thur-hike ending in Maine in the Spring (late March) thru Fall (early October?) of 2012

Do you guys think this is possible?? How many miles a day would a thru-hiker need to avg. to be in a kickass situation regarding the reality of linear time?

Thanks!! All the best to your late fall adventures
