I'm not participating, but since I got a new job back in september, I've lost just over 19 and a half pounds.. not quite the 20, but it's a pretty good success. I'm back to high school weight and quite happy about it.
Also super stoked, I'm going to need as much unnecessary weight burned off and as much endurance built as I can get, my gf and I are planning a serious trip DEEP into the Boundary Waters Canoe Area. Some of our days on the initial trip planning are going to have six portages.
When we get to our destination (as far deep as we can go in within our allotted time), I'm going to spend three days fly fishing for smallmouth bass, northern pike, and maybe muskies on relatively unfished waters on the MN/Ontario border.
