I know that Solinsky runs 100+mpw, and I've also heard him say that a huge chunk of that mileage is run at a tempoish pace.
My question is: what do high miles AND fast pace do for Solinsky? Obviously, yes, it helps him get faster, but how exactly?
Is he getting a stronger base? Is he training himself mentally to tolerate that pace? What sorts of physiological benefits is he getting that others aren't?
Your thoughts would be appreciated.
