a) thats what I mean to say – 400 not 200; and special endurance where I said speed reserve, sorry got discombobulated there
b)
But still is it necessary?
assuming top speed is the only problem I think it could be worked out inline with training for the 400.
So the special endurance in the 200 has a carryover to the 400? OR is the 200 just a great predictor of 400 speed based on other factors?
The 400m confuses and bewilders me
