Looking at all these PBs, national record and even some world records this year proves Lydiard was right. What did people do this year after covid cancelled most of the races? They extended their base phase. More time building up their strength. Once they set a date for a specific race, they sharpened up and because of their extended base, they set new PBs. This year prevented people from over racing racing and deterred people from putting in too much intensity. Hopefully people remember this lesson from 2020.
