Thank you for the replies.
I’ve been looking for beginner Olympic Tri plans and most of them have 2 to 3 runs per week at the beginner level, and 3 to 4 in the intermediate/advanced levels, with a gradual progression over the programs (adding distance to the long runs and some speed work/intervals). This is the same in the TR plan.
I’m sticking to 2 to 3 easy runs a week for now, and follow the progression of the plan. I prefer to add intensity to the bike workouts, which have a much lower chance of injury, and some cross-training benefits to running.
As for the swim, I’m watching youtube videos to learn drills and I’m trying to perfect my technique, but it’s very difficult to progress with pools being closed and with no lessons available. I guess I could try to find a coach to give some private lessons in the OW, but I don’t know if that’s even possible, and the cost would probably be too high. I guess I’ll have to continue with the youtube videos and the ocasional beach swim, at least until September.
