Makes sence.
He comes out of Spp3, full training, still under load and runs a few meets at great speed. As he freshens up from his comp phase and gets some more races in, then does his 10day taper, BOOM, Big Pb’s.
Spp2 Leads him into some early season races, 100’s
Spp 1 leads him into some 400’s etc
Until we hear from his coach, its only a guess??
You would have to see a graph of his race schedule for the last 12months to give you a more clearer idea
