In reply to greg_may_:
It would be an unwise in medicolegal matters, or inexperienced UK doctor that would sign any form of generic “fit for” form. The reason for this is that there is no reason for them apart from shifting the liability over to the person who signs them. Unfortunately it is a feature of British law (and I’m sure others) than even if you couldn’t have reasonably been expected to pick up some rare cardiac defect (for example) in the examination you perform, that you are still easily found liable for signing a statement that you shouldn’t have.
So either doctors will just refuse to get involved, which is simpler and safer ( it’s also completely unfunded work, so not covered by standard NHS funding and indemnity) or change the wording to a vague and wooly form such as “on the limited examination I performed today, I found no evidence of obvious reasons not to perform a normal level of exertion for the patients level of fitness. Responsibility for final decision, and liability, remain with the organising body”
These poorly designed “fit for” forms are gradually being weeded out in the UK, like the awful charity parachute forms, but for some reason they seem much more entrenched in France. I assume that it is much harder for a doctor who signs them there to end up in court.
This doesn’t help those who want to enter a French event, but provides some background to hopefully explain that GPs that don’t sign them are not just being awkward or obstructive.
