No, certainly not.
If you don't have to pay a registration fee, then you won't be charged a service fee either.
By the way, if a trainer or parent registers several athletes at once for which a registration fee must be paid, then only one service fee needs to be paid.
For example: if a trainer registers 30 athletes at the same time, that trainer will pay a one-time service charge of 0.99 euros. Another example: if you register an athlete who can participate for free, either through discount schemes or because participation is free for everyone, then no service charge applies.
