# Importing web page data

I tried importing a webpage using Import:

Import["http://ultrasignup.com/m_results_participant.aspx?fname=Troy&lname=Siemers"];

which should give some info about a runner friend of mine (he gave permission to have his name shown here). Using Import as shown above gives generic HTML information but the table containing the data I want. Using the options "Data" and "FullData" do not give anything useful, either. However, in my web browser I can see the HTML code for the table when I "View Source."

Is there an option for importing a web page in Mathematica that I am overlooking? How do I import the data from the page?

data = Import["http://ultrasignup.com/service/events.svc/history/Troy/Siemers", "JSON"];
