New to BT and lost about training logs

Welcome to the site!  There is a good amount of resources that are free which may work just as well for you-or to at least get your feet wet. 

First, there are the training plans, check them out per level.  If you joined a local tri club, are you following just some workouts or an actual training plan?  Also, what distance are you aiming for?  There are many free training plans at that above link that provide a good template as to the minutes you should train per each sport.  The silver/gold levels are more detailed plans where the gold lets you have unlimited questions and answers with our coaches from D3 multisport. Also the 'Choosing a Plan' article may help you evaluate your first season.

From the training details you mentioned, the 'Sprint 2x Balanced' plan, which is free, may be a good plan for you.

Likewise, a good part of the logs are free too if you just want some basic logging of workouts and some reports.  All the features of the log can be found here.  Complete instructions and articles can be found in the training log category:

Setting Up Your Triathlon Training Log

General Training Logging Procedure 

What I would do, is to start using the logs as-is now...see how you like it and get used to it.  Look at the various plans per level and see if they may work for you.  If in the future yo find you do want detailed plans and workouts or additional log functionality, you can add on later.

Good luck training!

As far as the 'minutes' programs (the free sprints and olys), the minutes increase 10% every week, with a 'rest' week the 4rth week of the month.  So it is some good, conservative building to avoid most overtraining issues.  If your rides already exceed that, there is no reason to shorten your rides to match the program-why sacrifice it as long as you have no problems doing the mileage?

As far as the short/medium/long workouts, as a rule of thumb, keep the long workouts EASY and you can alternatively build in some speedwork on the short/medium workouts.  But ONLY work on speed if you already have a decent base.  You can easily injure yourself a lot easier if you try to work on speed if you are still trying to build your base or volume-which may be the case for you in the run and swim.

I'm a little conservative so the sprint/oly minutes only programs are just that, a good template to force yourself to not overtrain by sticking with the minutes alloted - especially if you are new to the training volume.  Never push more distance/time over what ANY program calls for especially if it is uncharted territory.  Triathlon is kinda funny like that, the last thing you want to do is keep pushing yourself week after week trying to out-do the prior workout.  That will get you injured.  You need gradual build weeks coupled with rest weeks where you decrease as much as 50% in volume to keep you healthy and improving.
