What's his/her theory behind this particular workout? http://www.letsrun.com/forum/flat_read.php?board=1&id=27488&thread=27488#ixzz4Ill0tHVK Anyways, ET doesn't seem to mention 40yd-60meter dashes or any sort of pure speed work for mid-distance folks. Is ET's concept that a mid-distance dude/lady doesn't necessarily need to do months of 100m style training to develop their sprint speed/skill in a way that doesn't inhibit distance ability? Let's discuss!
