Can’t speak for others but as an amateur marathoner, this didn’t happen to me. The biggest thing I noticed wasn’t even that I sped up but that it reduced pain for the next day vs practice marathons I had run in my trainers. If I get richer I’ll switch to using race shoes for all runs for health reasons, not speed ones.
