I follow the results of marathons. It comes from being a Christian marathon runner, I suppose.
You can read the 2009 results of the Washington DC Suntrust National Marathon.
Now, mind you, if you ran home from the race, jumped online to see where you stood, you have probably come here too soon.
It takes a bit for the link/results to become current. In the meantime, you can compare your results to previous years.
Or you can calculate your pace, take into consideration that you will really slow down and figure what your time might be for 100 miles.
I ran the Rocky Raccoon 100 miler in 23 hours and change.
