I used the Pfitzinger 18 week 70 miles max week training program for marathons and it’s worked out well. I lowered my PR by 30 minutes on that program. My question is, has anybody here ever used a marathon training program for the Ironman run training? I’m doing Ironman Florida this year and am interested. I felt like I didn’t have enough miles with exact workouts for my last ironman. I was training for a 50 mile run at the same time so I was doing a few back to back workouts. Long run on Saturday followed by 10 miles on Sunday, But these were all fairly slow paced. A lot of the miles on the Pfitzinger 18/70 program are recovery miles, which I would scrap for swimming and cycling time. However, I was thinking of keeping the Mid Week long runs, for instance my max running week would be a midweek 15 mile run a Friday morning of 12 miles with 7 of those miles at half marathon pace, and a long run of 22 miles. There are 4 recovery runs that I would be skipping two 6 mile runs, a 5 mile run and a 4 mile run. But these are only recovery and are run extremely slow. Has anybody ever tried anything like this, and if so, how did it go?
