Ditto, the above, I had to provide medical certificates for some French and Italian cycling races. Just had a regular check-up with my doc in Zurich, it was pretty extensive check-up, and asked him to send me a letter that I was in good health or something basic like that which I then forwarded on with my application. The check-up should be good for a 6 to 9 months for this purpose, or I have been told.

I have heard of people getting quickie check-ups from French doctors, the day before a race.
