Yeah, there are medals. But the collection of them tends to be a quiet, understated affair. Usually performed in the privacy of your own home, rather than handed out routinely at the finish line.
I got mine at the finish line. I handed my Brevett card to Frank or Jos, they turn it over, look at the tick mark, and then rummage around in a bag, pull out a medal, realise it's the wrong one, rummage again, pull the same medal out, put it back, rummage around, and then produce the right medal... Maybe this is just how the Dutch do it...
