Anyone primarily a runner, cyclist, power-hiker, or otherwise mainly concentrate on endurance-related activities? (unlike all the meatheads in the Bobybuilding thread - LYMI). Right now I'm training for my first marathon which I'm running in January. I'm up to 15 miles but I know I can push further; I can pretty much run a half-marathon at this point with no problems. My half PR is something like 1hr 44mins, so I'm hoping to do the full in 4 hours flat or less. I'm also interested in speed-hiking and have a big goal in mind for that, which is an 80 mile through-hike of the longest trail in South Carolina. One of my friends has talked about doing this for a while, and I think we can get it done in about 40 hours. And as mentioned in the climbing thread, I'm big into mountaineering. My long-term goals there are considerably more lofty and are going to require a lot of time, money, and training to realize. Hopefully Denali in the summer of 2015 is the first big step.
