She is currently under management that believes nothing good can happen until she runs 120+ miles per week.
So, she dutifully makes herself build up her mileage to that level.
This effort is such that she doesn't have the luxury to focus on any kind of race-specific training at the moment. In fact, that effort is such that it might lead her to injury or overtraining...because it's not trivial to reach that kind of volume over the course of a single year.
Besides, high-mileage targets of that sort are outdated, I think. It works for some, but it's not a one-size-fits-all thing.
I would rather have her running 70-90 miles a week with 15-20 miles at target race pace, at 8,500ft, than 120 miles a week at 2 minutes slower than race pace.
All this is true and we can't forget that she is shredding her Achilles (every video has her doing exercises, caring for it, or addressing it) at just her current volume so I can't think an increase in mileage would help that
She’s defiantly overtraining at the moment. She is used to a large volume of training with triathlon but only ever hit 50 miles per week in that training. She’s doubled her mileage since switching to just running. As another poster mentioned, Jerry’s training is high volume and very hard. Despite the fact that she’s used to high volume and intensity with triathalong this is another level of difficulty for her body. At the moment she’s struggling to adapt. Most of the newbies to Jerry’s program face the same problem. Some get injured, some get fried, some thrive. Only time will tell.
