All of us at Team Trail Monster highly recommend Sydney's Bootcamp.
Lots of trail miles in boots, lots of rocks to scramble on, and even a few trees for climbing.
We are now in training for the Team Trail Monster Big Spring Bring on Summer Hike.
40+ Miles of Hiking on the Ozark Trail followed by 35+ miles of Floating down the Current River.
Duration 7 days... give or take a day or so for fun days and side trip hikes like Rocky Falls.
Check out a few more training pictures. We even practice first aid.
