A different type of system? Really, it's not that complex. Running is hard work and you either have the talent and drive or you don't. A different system is not going to help Jankowski, sorry. It's not like he was running 27:30 and then came over and went down. Your body doesn't know if you did a long run or repeat miles in Michigan or Utah. Work is work no matter where you do it. Yes, better weather plays a role over the winter, but that has nothing to do with Dave and his ability.
