That sucks for you man. To be honest, in January when it was clear sirpoc was doing the marathon I went all in on this method. I ran Manchester and ran 2:52 which is my first ever sub 3 in 12 attempts and only 10 finishes.
Never met the guy and don't know him, but read this thread to death and I figured two things. He's smart and I thought it he's running it, he pretty much knows this will work, as he isn't gonna put himself out there like that. The key for me was the long run and the time just getting used to being on ones feet that long, but still being able to do 3 workouts a week. I've tried Piftz a few times and Canova based ones scaled down, with a lot of 85% and then working up paced MP runs but I felt pretty cooked on that on hobby mileage.
If anyone is interested , all I did was basically train 2+ days behind sirpoc. I haven't spoken to him or anything. I just watched his Strava like a weirdo and scaled the distances to the time I had available. His 5x5k I had guessed was a touch faster than goal pace and I just made it into 5x15 mins for myself and so on. I think you get the idea.
Never felt so strong . It was a different experience for me yesterday. I had been training the normal sirpoc method for reference since last July, but this is my first marathon in that time. Personally I think you need a good few months probably of the original system, then that next phase and bringing in the new sub threshold distances slowly and then finally the special block, or whatever we call it? The special block for me was a huge confidence booster and the only time I really felt it was getting hard. The taper being just a week out came about the perfect time.
I didn't do anything really but easy in the final week. I think whatever method anyone uses we can all agree that's just preference and probably has zero impact on your race.
I had him down for sub 2:25. Even lexel of all people if you look at predictions pages back knew he was at least sub 2:25. I just didn't see a scenario where he would even start if it was not sub 2:30.
After about 5k yesterday I knew I was going to run sub 3 . Can't explain it just absolutely knew. Was glad to read on here today when he dust settled he absolutely crushed it. One of the many people sirpoc who owe you a beer! Cheers!
