Your first triathlon is going to be tough. Their is no way to sugar coat it. Go into it with the goal of hanvig fun and finishing it. Focus on your strengths. Running. Run 4-5 times a week and mix 2-4 days of biking in there. Make sure you do some brick workouts (ie. bike and then run workout right afterwords). Mix in some swim training when you can, and make sure your comfortable in open water (lake, ponds, river). This is prob more important than actually being good at swimming. Also, practice your transitions (taking off wetsuit, getting on bike, putting on running shoes), you can save alot of time, just by being good in between the swim, bike, and run.The training program you mentioned is decent, but it depends on what the distance of the triathlon is. Sprint Distance, Olympic Distance, other? I would personally always take one day off a week. I also don't substitute strength workout for a cardio workout, because the cardio is much more important in triathlon. The min amount of time you should spend training each time on the bike is 1hr, run 30-45min, and swim 30min.Hope this helps.
