the short intervals did almost as well as the 4 x 4 workout.

Much better thanks.

Interesting about the four hard minutes, four times. I do something very close once a week in the pool, 100m hard freestyle alternating with 50m relaxed backstroke. Not sure about doing it three times a week but may give it a go.
