What is you favourite tempo trainer range of speed ?

[yann]

Hi all,

Today I've reached the longest distance I ever swim without interruption: 200m ! Ok that's not much, but I'm trying to improve in ladder keeping my SPL in my "optimum" range (35-42 per 50m).

Now my question, which Tempo Trainer speed or range of speed do you use for your training. For me it's pretty slow: 1.4-2.0, with a preference at about 1.5

What about yours ? Is my TT speed something I should find very slow, slow or average?

Thanks !
Yann
