This is all good to hear (i think i was just getting paraniod)

Intend on doing the Lactate Threshold field test next week to see what that tells me.
Otherwise, I found an article on FT (functional threshold) training zones in a magazine, and results seem to sound a bit more accurate.

Here it is in case anyone would like to give it a go!

Use the formulae

For Women:
0.85 x (209-(0.9 x age))

For Men:
0.85 x (214-(0.8 x age))

Here are the training zones printed in the article also.

Easy: 69%-83% (warm-ups etc)
Steady: 84%-94% (Long rides)
Brisk: 95%-105% (Long efforts 10-20mins)
Hard: 106%+(Efforts lasting 2-8mins)
Very hard: working flat out! (Less that 2min efforts!)
