I'm 3 months into my triathlon training, all this long distance has been tougher than I thought it would be. So far the farthest I've gone swimming is 1 mile, the farthest I've biked is about 11 miles, and the farthest I've run is 9 smiles.
Although I have been keeping track of times, I'm more focused on the distance for now. I swam the mile in 36 minutes, I don't remember the bike time, and ran a 10k in 49 minutes.
I still get in the weight room and do things like upper body free weights, pull up, and other core exercises. I do the 300 workout probably once a week, swim every other week, bike once a week, and run 2-3 times a week. Once I become more accustomed to this I'll start doing more workouts.
