There are 5 peaks in Vermont over 4000 feet: Mount Mansfield, Camel's Hump, Mount Abraham, Mount Ellen, and Killington Peak. They are all easily accessible from roads.
I plan on summit all 5 in one day, tomorrow 8/22/15, (basically as fast as i can), and using the same rules as the NH 4000ers. Meaning, the clock starts at the trailhead for the first mountain, and ends at the top of the last mountain. I know people have already done this, so treat my attempt as just a starting point for other people to post their faster times. Woohoo!
Well i got them all done yesterday. My garmin watch died after the second hike (Mansfield), so i had to use my phone for the remaining two (and three) hikes. Here's the GPS tracks. I started at 6:37am for Killington, then did Mansfield, Camel's Hump, Abraham, and Ellen, summitting Ellen at 6:37pm, so 12 hours exactly.
