The purpose of this test is to establish the extent to
which an athletes body can cope with increased levels of lactic acid within their
system.
Prior to performing this test, it would be useful, though not essential,
to find out what the athletes pure speed is like, by using the flying 30s test.
It is not essential as here we are trying to predict the drop-off in performance
over two runs where the first is run primarily as a speed endurance run - with
elevated, but not very high, levels of lactic acid.
This first run is to get as far as possible in 30 seconds.
Take a total recovery, 20 minutes should be adequate for this, and then
run a 600m time trial as fast as possible.
