I think you are replying to me although you quoted Kuudere. LOL.
I didn't achieve my goal, and I believe TAO's philosophy of conducting more back-to-back training with less mileage per single run, as opposed to other plans that require a run longer than 32km during the peak phase, may be a factor. This time, TAO's longest run was only 24.5km at peak. I had a feeling that wouldn't suffice, but the TAO coach assured me it was sufficient, citing a study that lower mileage with more frequent back-to-back runs is beneficial for casual runners. Consequently, I suspect this is why my legs failed around the 32km mark. I was maintaining a good pace in zone 2/3, over 5:35, until about 27km when I started to feel leg fatigue, which worried me. True enough, at 32km, my legs reached their limit, and I had to alternate between walking and running from that point on.
But the positive part is my LT1 has improved significantly, and I noticed it during tapering. LT1 prior to training, was around 5:56 min/km. After training, it was around 5:40min/km.
Do note, that I already used TAO for last year SCSM and sees it's benefit of lesser single run mileage during peak with back to back training. I managed to run the whole course last year without the legs giving up, san the sheare bridge, But then, Tao gave me two single runs at 27km. But my pace was slower than this year, as my LT1 then was around 5:56-6min.km.
Note , both last year and this year resulted in a PB from a timing I had hovering around 4:35 prior to TAO.
So next year, I am continuing with TAO, but I will watch out for the peak phase and increase that mileage to 27km myself if TAO is not giving me that 27klm single run training.
Good luck with Runna, do let us know how the training like and how different is it with TAO.
