Charlie- given that Stephen Francis said Asafa ran a best of 32.8 for 300m on grass, the 37sec 300s in training would put him a little under 90% and higher for the other guys. That looks like they are putting some emphasis on longer runs especially if (as SF said) they do up to six reps of 300m. How intense do the longer runs have to be in order to “qualify” as L-S? I assume its an intensity issue since 6x300m is significantly more volume than the 24x40m hills?
