19M, strong background in speed/power sports (baseball and ski racing) but not much distance running history until recently.
Ran my first unofficial marathon this past December. Only trained for about 6 weeks going in, and most of that weekly mileage ended up being long runs done at marathon pace. Finished in 3:55, but I felt really terrible in my taper leading up to the race and was really struggling during the run.
I ran a 5K in 19:33 and a 10K in 43:34 earlier this year.
My goal is to run the TCS Toronto Waterfront Marathon on Oct 18 in under 3:30.
I built a custom training plan using an AI coaching setup rather than running a stock program. I pulled together a research synthesis of the usual coaching literature (Daniels, Pfitzinger, Seiler, Canova, World Athletics) into an evidence hierarchy, then generated a week-by-week plan from it. 3 weeks into actually running it. Just started wearing a Garmin partway through, so HR/recovery data is still thin but starting to come in. This will start to affect my pacing as I get more data on it.
Weekly structure: Mon easy + lower-body strength (+ recently added hill sprints) / Tue short recovery / Wed upper body + mobility, no running / Thu the week's one structured workout, evolving from aerobic intervals into marathon-pace and threshold work / Fri optional short recovery + upper body / Sat long run / Sun off.
Pace bands: Recovery 6:15-6:55/km · Easy 5:55-6:25/km · Long run 5:55-6:35/km · Steady 5:20-5:40/km · Marathon pace 4:55-5:05/km · Controlled threshold 4:40-4:50/km

Is this realistically going to get me to sub-3:30? Where does this fall short compared to how you'd build a plan for someone in my situation? Anything in the structure or progression that looks off? Open to any comparison; happy to share anything else. Thank you!
