1. I prefer weight lifting to running, but<p>2. I think you&#x27;re pretty off base. The gains for running are just as correlated to your training, and (IMO, obviously, it&#x27;s unquantifiable) a 10% speed improvement feels exactly as good as a 10% weight increase.<p>(For reference, I&#x27;ve been a medium good runner and lifter: at my various peaks I&#x27;ve run consistent sub-18 5ks and squatted 5x315lbs)
