Well shucks. I don't have any time limits but this thread has been real informative.
Last time I headed north from Springer Apr. 3rd. Outside of regular zeroes I had about 24 days off the trail completely for injury, work, trail days. I estimate 3-4 weeks of zeroes besides that. I ended up not finishing due to "time limit". With Maine cold as hell in early Oct. and Baxter park closure I ended my hike Oct. 11th before entering the 100 mi Wilderness. The time off for work really cost me. Not only the time at work but the lack of miles achieved once back on the trail due to having to rebuild Trail legs.
I was was planning on starting early March this time around to give myself plenty of time to take it slow early on, still take lots of zeroes, and finish sometime in September. After reading this thread and others since joining whiteblaze a couple weeks ago, I'm not so sure on my starting time. But I still wanna take it slow in the beggining to avoid I just and take plenty of days off. I think I'll be all right starting early April again
