Got into running and triathlon. Started out 3 years ago with light running mostly on treadmill during the winter. Ran two half marathons and then one year later ran a full marathon. After that I spent three months preparing for half ironman distance triathlon. That was much fun, race as well. Last year was most time intensive, I've spent about 6 hours running/swimming/biking a week, which is not that big of a jump as I use to go to gym for about 3-4 times a week. Effort is interesting since I had to reduce the intensity to build up the endurance, so workouts we're not difficult at all. I prefer it over other stuff since it makes me active and I enjoy the endurance workouts.
