Classic STW response: it depends on the coach and client.
Some have training groups to train with, others are all done by email/phone and only meet face to face once a year.
Some do full physiological testing at rest and on the bike, others might get you to do a test which is more specific- eg how fast you do a certain ride/loop and repeat it at full pace once every 3 months as a marker.
In general the more that they know about you the better the training will suit you.
alwillis. That’s what I thought, does it work? See to me it seems like a coach is to far detached to be dictating how you should ride on a weekly basis. Sort of do this for three months and see me, ‘ah that didn’t work’. Try this instead for the next three months and see me.
