As I suggested in part I of this post, I suggest you keep a simple log of your workouts to track your progress and how you are training. When I mean simple I don’t mean something sloppy, I mean something easy to fill out every day after every workout, because if it is too complicated to fill, you will not input the information on a daily basis. So my advice is to invest initially in a good log that will be easy to fill out and then just update it every day (even on your rest days)
I will use my training log (for 1/2 ironman) and you can adapt your from my example.
The sheets I have setup are as follows:

The Plan and By Week sheets are explained in part I.
Sheet 3: Schedule
This sheet also could use a better name. I use this sheet to get an overview of the day in all the sports:

I use it also to write any comments, like “feeling sick”, “bad night”, “knee pain”, etc.
So on the first column I have dates (sat and Sunday are gray). Then I have a column for each sport (Bike, Run, Swim, Core and Rest). I don’t write on this sheet, except on the rest column and on the comments.
This sheets pulls the information from all the other sheets, with a very simple formula.
For example on the bike column, I have the formula: =IF(Bike!B151>0,Bike!B151,”N/A”).
This means in non-geek terms: If I trained my bike for that day, post the training I did, if not, then post N/A. As you can also see the days I have any activity in that sport, it changes color from white to yellow. I do this with conditional formatting in Excel. I have it setup this way:

Again the idea of this sheet is to get a clear, daily view of what you are doing (again) on a daily basis, so you can track your progress. This is not an input sheet (only comments and rest)
Sheet 4: Bike
This sheet depends a lot on your training and what you want to measure (which is key).
I have the columns Date, Description, Focus, Route, Warm up time, Total Time and Total distance.

I have it setup this way, because I want to track what I do (my focus), my time and the distance.
From Column P and Q y get the information to display on the Schedule Sheet. On this sheet I have no colors, since it only helps me to input information, not to analyze it that much.
Sheet 5: Run
This sheet is probably the most complicated sheet for me and again it depends a lot on your training and what you want to measure.

(I have spited the image to show it better)
Column A has date, column B description, columns C Laps for any speed work or track days, D is distance, E is Warm up / Rec is the warm up and recovery distance, F is target Pace.
I guess this is self explanatory. O the 5th of January I did speed work of 10×200 (SI) is my sign for the speed I had to go at. And the pace was 0:45 per 200.

So on track days, i fill out the columns of each workout (in this example it was 10×200), so I recorded all 10 200 m runs. On Q I added the total time and then on R I setup the average time of my 200 m runs. S is total distance.
Then I have a column (not shown) of the total time of the workout, this total time and the total distance is what i display on the Schedule worksheet.
Again, the idea is that i only input information from column B to P all else should be calculated automatically so I don’t have to spend too much time on my log.
Sheet 6: Swimming
This sheet is very similar to the running sheet, since I record the laps and the time for each lap.
Sheet 7: Core

This is very simple, you can list all your core exercises and just enter the sets and the time or times. For example I do the plank 2 times for 40 seconds.
You can read about core exercises here and here.
I hope these two LONG posts can help you start your own training log. From my experience the more complex information I want to fill out, the less I update it, so my best advice would be to keep the input very very simple. Around the input you can automate graphs and sheets that can give you a feedback on how you are training, but keep the input easy.
