First Marathon in November – Best Training Plan After a 70.3?

Hey everyone!

I’m looking for advice on the best marathon training plan for my first marathon, which I’d like to do in mid-November.

Background:

I’ve been training for a 70.3 Ironman in mid-July since late December, following Phil Mosley’s beginner plan.

Right now, I’m training 8-10 hours per week (2 swims, 2 bikes, 2 runs).

My current running ability: I ran a 1:48 half marathon in November last year and a 1:45:56 last Sunday, but my overall training volume is balanced across three sports.

My Goal:

After the 70.3 in July, I want to shift my focus to running and train for my first marathon in mid-November.

I’d love to hear your recommendations on the best plan to follow post-70.3 to build up for a strong marathon while allowing for proper recovery. Hal Higdon, Hansons, Garmin, others...

Would a traditional 16-week marathon plan be too much after a 70.3? Should I take a break, then ramp up? Any guidance is much appreciated!

Thanks in advance!
