I weigh 200lbs plus. I have a Kinesis Fork with a 1 inch CF steerer on my Merlin, with a few spacers under the stem. I've put 10,000 plus miles on the setup, including 50mph descents down the Col de Aubisque and lived to tell the tale.
I wouldn't worry about it. (Besides, if you're lucky they will be someone around to throw you a few tubulars strung together).
