50 mile training plan.

I would not recommend Pftiz marathon plans for 50-miler training, unless you've raced long ultras before and plan on being very competitive. The Pfitz plans I've used include a lot of VO2 Max, Lactate Threashold, and Tempo Work. While these plans have a lot of mileage, they're designed to help you optimize your marathon performance.

I'd suggest doing a web search for 50-mile training plans and comparing them. Most 50-mile specific plans will probably be similar to or fewer miles than the Pfitz plan you referenced, but will focus on at least one (and quite often two) long run per week. Hal Higdon has a free plan on his site you can take a look at. When his mileage gets up to 70+, his plan calls for 4-5 hours on Saturday and 3-4 hours on Sunday....both usually done at very low intensity.

I'd suggest a web search for 50-mile plans, comparing them, and choosing one that fits your lifestyle and time you have available for training the best.

I think be cautious with this. I used to think that if I was doing 110km a week with speed work, like seriously, is there anything I couldn't do. Truth is I never got to the 70 mile a week phase, well I did, but then I crashed and burned after 8 weeks.

I had this theory last year training for my 100 miler that a hardcore marathon plan was all I needed. I was a bit wrong on that in retrospect. Mainly I think because a 2-3 hour long run, even at MP, while difficult in the middle of a 50-70 mile week, really does not prepare you for 10+ hours on your feet. Well, I don't know, it might. But it doesn't prepare you for 30+ hours. I tend to think, if you can handle it, a phitz type plan with some 5-10 hour grinds every other week at your ultra pace over your ultra terrain would be best, if you could handle that. But I don't know, really just spit balling here.

Thanks

I found "Relentless Forward Progress" by Bryon Powell. I like his training plan and have been using that.

I used his training plan before. It's a solid plan. Was very prepared, I thought.

I meant I used the plan in relentless forward progress.

I've also used pfitz but only for marathons
