I looked into this a while ago - there are no "affiliated" coaches in the Uk...and you have to, I think, go via a coach.
Did think about doing this remotely, but far to much hassle. Would be interested in VLa Max assessment, but given my strengths as a rider, I can already sort of guess with a reasonable degree of certainty. Other than that, not sure it would be worth the expense.
I looked at it for my coaching but it’s FAR too expensive for me, I’d have to pass the cost onto the athletes and I’d lose them all...
