Hi Jonny!
I've been using Matt's 70.3 plans from the Fast Track Triathlete book now for a season and a half - really enjoying them, especially how he gives the purpose of each session and also some options depending on time and fatigue level. Planning to use the 140.6 plan for my first full-distance race in Chatty next year as my B race, and modify it for 70.3 WC in St George as my A race. (yes they're insanely close - I'm going to enjoy the process!)
I'm reading your question as to whether anyone has "uploaded" or entered the plan into a structured format like TrainingPeaks/etc/etc - and so far I haven't seen anyone that has, at least not for no-cost. From what I understand, if you join Purple Patch (Dixon's camp/team) you also get a free account to Today's Plan - and the workouts are customized for you to some degree and you get the digital structure through there on your device, enter the post-workout log into the app, etc.
Here's a post to how I've used the plans on a daily basis
https://forum.slowtwitch.com/...ost=7404518#p7404518. Essentially, I cut the pages from the book, scanned them to PDF, loaded it to my phone, and use the "Books" app on my iPhone to memorize the session and then I execute it from memory (except the swims which sometimes take an extra look or two during the session as they tend to bigger or more complex). I use Training Peaks to analyze my session afterwards, and don't sweat whether or not I hit everything to the exact second, instead focusing on the quality of my work.
Hit me up on a PM if you think the PDF would be of interest - can give you a better feel of what it looks like.
Hope this helps!
Travis
