Here is part of a Renato post from page 2 of the giant thread where he talks about how Bungei's coach had him do 600s with the last 200 faster pace than the first 400. For Bungei (1:42 guy, so race pace is faster than 1:18) he averaged 1:21.5 for 4 x 600:
I want to describe, for example, one type of training that Gianni Ghidini (the current coach of Bungei, Yiampoy and Kamal) and me use with these guys during the last period, having the goal to IMPROVE SPECIFIC ENDURANCE, developing intensity from the Threshold to Specific Endurance.
1) 6 x 600m (rec. 4 min) in 1:28 (60/28) 1:28 (60/28) 1:27 (60/27) 1:27 (60/27) 1:26 (60/26) 1:26 (60/26)
2) (about 10 days later) 5 x 600 (rec. 5 min) in 1:26 (60/26) 1:25 (59/26) 1:25 (59/26) 1:24 (59/25) 1:24 (59/25)
3) (about 10 days later) 4 x 600 (rec. 6 min) in 1:23 (57/26) 1:22 (57/25) 1:21 (57/24) 1:20 (56/24)
4) (about 10 days later, in the case of Bungei 8 days before Zurich) 3 x 600 (rec. 8 min) in 1:19.3 (54.2/25.1) 1:19.5 (54.6/24.9) 1:17.2 (53.0/24.2)
The next workout (before OG) will be 2 x 600 (rec. 10 min) in 1:16 (52/24).
