Just going by a few instances on Reddit reviews of Runna and to be fair my bar would be alot higher. I've been fortunate enough to do cycles with coaches that been to Olympics and Coach Bennett in person when Nike first had the run clubs. The week before I broke 3 for the first time i ran...
It uses AI and is famous for overly aggressive plans from what i seen. If the budget is decent would just get a actual coach. My past one would write my program weekly based on how i reacted to the workouts.
She had 4:04/05 if they paced 61s. Obviously that wasn't happening since the event was breaking 4. She was pressing to run 60.2 at 400 so ended up cooked by 1000m.
Wish her the best but 7 seconds is a eternity to cut. Especially since she ran 2:29.21 for that 1000m diamond league meet in April which is 4 minute pace.
it happens quicker on VF3 compared to previous models (I heel strike during easy miles). I could see visible outsole wear after my first run. Actually ended up returning them soon after since the ride wasn't as aggressive as i wanted like the OG or the 2.
Good video she just forget to mention the shoe ruling got amended and pros are allowed to wear prototypes for up to a year as long as World Athletics looks at it first.
