These are the pursuits I am currently involved in:
Mountain Biking, I ride local trails, have raced a bunch of 100 mile events including the Leadville 100.
Road Biking, I ride with local groups, have done the Hotter than Hell 100, The Hell and Back 440, Numerous state/ local 100's, and 200/300K randonneur events.
Trail and Road Running, Have done a few half marathons both on and off road. Trained for a 50K trail run a few years back but got sidelined with work.
Backpacking, I have a goal of doing the Tahoe rim loop one day. Have backpacked in OK, CO, NM, AR, and would go more often if I had someone to join me. Do not believe that car camping qualifies.
Adventure Racing, I have competed in 3 hour sprints up to 3 day events. At one time was training for an Eco-Challenge but could never find 3 other locals crazy enough to join me.
Some other things I've tried... Skydiving, Race Car driving (NASCAR, and Formula 4), Bull Riding, Golf (hated it), Surfing, Mountaineering, Bungee Jumping, White Water Rafting, Sailboat Racing (mono and cats).
Things I would like to try... that list would be quite long.
