400m S-L questions

[Charlie_Francis]

@John

Did you ever do / consider using running A’s for the back up on split runs? Example week 11 of S-L instead of 200+200 doing 200 @ above race pace then 25 seconds running A’s?

Would this have merit?

This concept was used by Gerrard Mach often in the GPP- ie 2 or 3 x [80m bound followed by 200m run followed by 50m running As]
